Spent yesterday squeek and rattle testing in the feild, My 1500 Midegt has now put another 2 miles on its odometer (first movement it has seen in 16 years).. Found a loose shock boly, a loose wheel bearing and that I had only started the fuel pipe union into the tank and not done it up.. once it was all done it drove reaonably well.. apart form one thing, the clutch is still not working properly.. If you hold it down in 1st, the car gradually creeps off, my suspision is it fluid is leaking past the seals back... MORE
"'67...the best of years"! But the engines, Stewart.... they were sweet...just right. No emissions but a PCV system...and leaded fuel was still around so 10.0-1 or greater was NOT a problem! Ahhhh...for the good ole' days! :) Cap'n Bob '60 Frog "Robert E. Shlafer" 36373... MORE
I put a little bit of Teflon tape (like you use on gas & water pipes) on the brake line threads. Be careful not to do too much, because you do not want a pice of tape floating through your brake system. I have had no leaks yet in my system, pipe-wise. Oh, and don't over-tighten threads; they will strip. as Adam J.Kopff 36322... MORE
stewart you are correct to use 35 amp fuse.i am nearly sure the fuse in question protects indicators,fuel gauge and heater blower and operates when ignition switch is on.i had a similar problem on my 1977 1500 midget and found the problem was caused by worn wires on the indicator stalk shorting. to rectify,unscrew four screws that secure the cowls to the steering column remove lower cowl then move upper cowl in anti-clockwise direction round steering column,depress horn slip-ring contact and ease the cowl off the column.remove clip holding the switch wiring harness to the steering column and disconect...

Sure you can use a generic fuel pump. All the car parts stores sell them for about $30. I wouldn't use nylon fuel lines. What reason could there ne not to use metal ones? As far as using the cam from your 1098 - why? It's probably worn some, so why not just go for a new one, say a Kent 256 or 266. You'll get improved performance, and they aren't very expensive. Be certain to use new lifters. Why do you need new rockers? The old ones can be rebushed easily. "joe blxfstz" 36151... MORE
Well the SoCal weathermen were wrong again! It was suppose start raining again yesterday and today - but all the rain stayed north in Los Angeles County. Orange County is sunny, mid-70s. So I decided to drive the bugeye up to a client meeting today . I had just replaced the RC40 muffler (riped off on freeway) with a cheaper Thrush Cherry bomb from NAPA. I liked the sound of the RC40 (throaty but smooth) - but I like the Cherry bomb much better (slightly louder, definitely raspier). Kinda the difference between white wine and Irish Whisky. Bugeye ran... MORE
No, Ed. It's not a myth. I am an electrochemist, and I've made my living in that field since 1964. I've published articles in peer reviewed journals, and I am certified by the American Electroplater's and Surface Finisher's Society. I have served on ASTM panels writing recommended metal finishing practices, and I am certified to give legal testimony as an expert witness in this field. Here's a quickie explanation. In order to oxidize metals, a positive ion has to form, that is Fe has to convert to Fe+2 in order to form iron oxide (rust). When you impose a... MORE

Has anyone tried the modifications listed in the bl st manual? I mean adding twin hs4 SU carbs, a race distributor (part number C-27H7766), a head with 9.5:1 compression, and a free flow exhaust? The performance figures make this look tempting. Too bad I dont see anything about gas milege or emissions (in the unites staes this can be an issue. "gan5ub91179g" 36012... MORE
Well Herb, et al. The Company is a consulting engineering outfit called Ricardo . http://www.ricardo.com/investorCentre/investorCorpProfile.asp Started life pre WW1 when the founder doubled the efficiency of diesel engines in the very first WW1 tanks.(I understand the exhaust exited in the tank also , so the enemy wouldn't see them coming - the early tank crews did not last long !!! He used his experience on improving early Triumph motorcycles, on combustion chamber shape mainly and camshafts (Along with Weslake). "Alan" 35852... MORE
Dear Virgil and all, I have a block. I am not sure what it is but I am sure those on the list can tell me. It is very available in San Diego. Here is the hard part, get ready to laugh at me or yell names etc. It had been setting out in the rain for god knows how many years. There is surface rust inside and outside. The rust is not bad but it looks like hell. I am sure sand blasting or hot tanking it would make it ok. It has a pan, quite a bit... MORE
Chuck...do not be mislead by compression ratios which could be had back when leaded ("manly") octanes were available . Today's unleaded "garbage" octanes require a little more thought in this di rection, assuming a cast iron head and the ignition advance curve you're probably working with, along with a "mild" cam with relatively little duration which will favor maximum "trapping" of the combustion gases in favor of the low end of the useable rpm spectrum (torque.. as in street application). With aluminum heads you can go about a point higher than with cast iron, all else being equal. Also,... MORE
I need to replace the floor of the trunk in my 74 RWA. How difficult is this and what is the process for fitment? I know the gas tank must be dropped and I need to replace the floor and the 2 filler pieces on the sides that go between the floor and the wings. "Richard Rivenbark" 35624... MORE
Hey cap'n Bob, I saw the Nology guys at a M/C show and they had this great display which showed a nice bright spark. Much brighter than the spark in the carbon core setup next to it. But they had no Technical backup other than this will incrase your HP, Torque, Fuel Economy etc. I guess I'm just a Cynic. But Mr Vizzard...I'd trust his judgment. -Spence "spencer_baker" 35612...

Jim... most people convert their points ign. system to electronic Crane, PerTronix (Lucas/Aldon "Ignitor") to get away from the maintenance schedule which must be followed to retain the intial efficiency of the stock points system when new points are installed and concurrently, dwell and timing are accurately set. For as you know, as the points wear, dwell and timing change. Thus, every 3k miles or so, resetting these values is the only way to maintain original efficiency of the points type system. Simply converting to the foregoing electronic systems while maintaining the otherwise stock coil does away with the... MORE
The "longer" spark is supposed to lead to more complete combustion of the fuel/air mix which should be better for power and/or economy along with fewer emissions. Of course, for the "longer" spark, you need more "juice" to begin with..... :) Cap'n Bob '60 Frog "Robert E. Shlafer" 35606... MORE
Ken, If you use a catch can, and run any hoses up vertically for any distance at all, I don't think you need any baffles. Any oil that pukes out will end up on the sides of the hose and run back down into the crankcase unless there is such a rush of air out of there to carry it into the tank. I think don't worry about it. Bob "Robert D. Gardner" 35534... MORE
Mitch..IMHO.... if you are going to use the Judson, I would call APT and source the best quality valve they have to offer. Otherwise, unless you've got a hairy cam in there or are running 10.0-1 or a higher static compression ratio, standard quality/design should be fine normally aspirated. About oversized exhaust valves....many moons ago when the first 1275 Cooper S types came out, they went with a larger 1.4 intake valve and subsequently, went to a larger than stock exh.valve to "match", feeling this would give more powe r. It didn't. What it did do was lead to... MORE
Welcome aboard, Jim... You've already recieved good answers to your questions so no need to further "go there" with one exception.... 145x13's can be hard to find these days, though your local Sears probably has them. 155X13's are easier to source (Town Fair and most others stock them) and will do just as well, while giving even better grip and fuel economy all else being equal (fewer revs per mile per hour) without nearly a gnat's eye change in ride quality. :) Cap'n.

Ah....I percieve, Jens! What they've provided is basically their road "performance" curve contained in their "Y" (yellow) commercially available dizzies. The chart they included is the actual advance curve contained within the distributor. This would be in "distributor degrees" Jens, at "distributor rpm". Double the figures in each case for engine rpm and advance available at the crank. Then add in the initial static timing recommendation (4-6 degrees) to the foregoing figures and you'll know how many degrees you are getting at the crank at any rpm, per their "static" timing recommendation. Now, the above is for academic interest... MORE
Thankyou, Jens.... I am going to assume based upon the information you gave them on compression ratio, they assume you know enough to use the highest legal (unleaded) octane commercially available and in Europe, this is 98RON as far as I know. Did they include any recommendation as to total timing or set-up? Cap'n. Bob '60 :{) PilotRob@... 33609... MORE
Jens.... They recurved it based upon the information you provided them on the spec of the motor/octane used?? Cap'n. Bob '60 :{) PilotRob@... 33604... MORE
Chris... There ARE disadvantages to "in trunk" mounting, no doubt about it. In both my past and current positions I have been trained to think worst case scenarios first and foremost. And I would not personally install a pump on the "inside" myself, for in event of accident, I personally would rather have it ALL "outside" the car, whether I had a "g" cutoff switch intalled or not. However....under normal circumstances, we are not talking the pressures of fuel injection. Leakage of any sort should be detected very quickly considering only pressboard separates the trunk from the cockpit and... MORE
Jens...suggestion? Go out and purchase a simple Facet solid state electric fuel pump with it's own "incoming" filter. You want the low pressure one, around 3-4psi. Cut out a piece of rubber gasket to place between the pump/body and install it where the stock SU pump went (according to your Haynes manual or whatever you are using) in later cars. This pump will work with SU's just fine without a pressure regulator. Cap'n. Bob '60 :{) PilotRob@... 33377... MORE
