I have quite a lot of old SU literature here, courtesy of an old 'motor-racing' friend of mine who many years ago had a tuning shop, but as many of us do, never threw anything out! He's now passed most of that information onto me now, I have a whole host of information relating to Solex carbs! If I do come across anything else that may be... MORE
the AUD328 is a 'ventilated' type ie has the angled ports coming off the side to connect to the crankcase ventilation system and also has a bias sprung needle (no centering required). The other two are non-ventilated and use the original style needle. I'm not sure of the detail differences between AUD136 and AUD266, but I'm pretty sure they will be functionally interchangeable.(Incidentally, for a given size of SU, the jets will be the same diameter across the whole range) Regards David 27446...

Duncan I'm not really sure either, but I think it's by 'application' ie what car they were fitted to. eg AUD136 was fitted to the Midget MkII, 1098, 1964 and AH Sprite MKIII 1963/4 and MKIII, 1968/9 Needle sizes were RICH H6, STD AN, Weak GG Blue Spring Colour AUD266 was fitted to the Midget MkIII, 1275 USA spec 1968 Needle sizes were STD AN, Blue Spring AUD328 was fitted to the Midget MKIII, 1275 USA spec, 1968/9 Needle sizes were STD AAC, Blue Spring From what I can tell all the HS2 throttle sizes were 1/1/4.

Jim... Since you've gone with an Ignitor (PerTronix?) why not go with the same (PerTronix) wires. Assume (ass-u-me) you are using one of their coils as well? Otherwise, Accel, NGK, Magnecor, etc. are available at performance speed shops. Go with a metal conductor type like the original Lucas "Bumblebee" performance wire more or less, in 7 or 8mm depending upon whether you choose to use the stock Lucas resistor tips. If you really want to go crazy with wires and want something really wild and very well insulated (and "built")....go Nology Hot Wires. Vizard dynoed these and found they... MORE
Before I install the wrong spark plugs and poke a hole in the top of a piston or two, I thought I better get some professional help from the group. I've installed the Ignitor and a 40K coil, now I don't know what range plug to install. I'm equally unsure about the plug wires. The other up-grades to this engine are a Kent 266 cam, bored 20 over and fully balanced with an aluminum flywheel. What combination of spark plugs and wires would be best suited to this engine.

Thanks to Pilot Rob, Duncan, and David C. for responses. To answer collectively, fuel is being fed to the carb. Last time running wasn't too long ago. I removed the brake MC for resleeving/rebuild at the time, and decided then to address the pedal box area corrosion. I have not yet tried, as Duncan suggested, to hold No1 wire close to the block (3/8") and check for a spark. Since I haven't mucked with anything near the plugs/dizzy/carb, suspect lack of juice to the plugs is not the issue. I'm going to swap out the coil to see if... MORE
Hmmm... Too bad. Khumo and Yoko make some pretty good tires!! The foregoing having been said: ...T/A's provide excellent performance and ride, whether Comp or Touring. Prices are very reasonable. Cap'n. Bob '60 :{) PilotRob@... 27420... MORE

Hi, I have a question relating to SU HS2 carbs. Is there a way to tell what the differences between the model numbers are by the numbers themselves. For example how can you tell the difference between the AUD136,AUD266 and ADU328? They are all HS2 after all Is it just needle size and spec, jet size that differ? Any advice appreciated TIA Duncan "Duncan Sinclair" 27417... MORE
Hello all, I'm sure someone out there can help, and would greatly appreciate any or all feedback regarding this one. The engine is turning, but not starting. I have a spark at the coil, and the dizzy has not been touched since last start. The coil is the ballast type with resistor, and the wires were moved, in order to address a bit of corrosion in the pedal box area, but all wires were returned to their original position. Thanks in advance for any words of advice regarding a fix. Pete 78 midget Granville, OH "Pete Skalski" 27356... MORE
Peter... You got spark to the plugs? You got fuel to the plugs? Cap'n. Bob '60 :{) PilotRob@... 27357... MORE
Yep..you got it all, and you got it right. However....while I personally like running well vented, there is nothing wrong with the simple pre-'68 intake manifold mounted, diaphragm equipped PCV valve fed from the timing case cover. This is a good KISS (keep-it-simple- stupid) PCV system teamed with the filtered oil filler cap. There is virtually no maintenance to this system besides renewing the cap once a year and the rubber diaphragm when it becomes porous (the engine begins smoking out the exhaust and using oil like crazy when this occurs...so you'll know "when"!:). If you have decided to... MORE
Got the dashboard out the other day as its getting now to that stage in the rebuild,but had forgot about all the extra holes that had been put in it over the years from the last owners,like the extrta two 2" holes and four switch holes oh well,so had a ring round no new units at presant but we can supply you with a recondioned unit,well the price was not bad so said send it,well it came today and in my mind had it fitted by tea time clocks and all,out of the box it came and back in...

Jim... OK...you want to run "vented" instead of "closed loop" but wish to retain the charcoal cannister and use it as a catch can either in it's present position or possibly elsewhere in the engine compartment. Fine...but you MUST promise to read the last paragraph! :) I am strictly a layman in the post '67 emissions systems which were strapped to our engines as "add on" devici, providing for a "closed loop" system to ensure crankcase/fuel tank vapor evacuation into the combustion process. Ripped it out myself, and never used one. I took a look at it under the... MORE
try swapping the plug leads round to suit the correct firing order then (1,3,4,2?) - a bit easier than ending up with the distributor pointing somewhere inaccessible. David "David Jacobs" 27261... MORE
My friends, Please excuse the NO LBC CONTENT. As many of you know, my son Alex in in Iraq. He is in an area north of Baghdad with the US Army's 4th Infantry Division. Last Sunday they were in a big ambush, firefight where 6 of their men were wounded and 46 enemy were killed. He is in a dangerous place and has 3 little kids at home who won't see their dad for Christmas. He won't be home until April. It would be a huge favor to his mom and I if, when you are sending Holiday cards... MORE
Might seem a bit noddy.... 1. I have a +ve earth Sprite, can you jump start with a -ve earth Car? If so is it straight forward + to + and - to - ? 2. What's the name of the engine tuning house, sounds like Oliseti, or Oseti? Max "Max" 27248... MORE
"Speed" Agree with your take on this, Bob. I love Corvettes but, unless you live out in the midwest or something like that, where you gonna use the speed? Would much rather be drivin' a "go kart" like a Spridget at much less expense, any day. :) IMHO, "less" is most certainly "more" in this case! :) Cap'n. Bob '60 :{) PilotRob@... 27244... MORE
Duncan... First choice: pick up the later timing case cover and utilize the intended stock simple PCV system. It works very well. You see, the Series A motor has a scroll (oil thrower) affair back by the main bearing which depends upon tight metal (block) clearances for "oil tightness". The motor does not have a "regular" rear main oil seal, Duncan. Without the stock PCV system, these motors have a real tendency to leak oil out of this area, most especially as they build miles on the crankshaft. The stock PCV system will draw out crankcase PRESSURE along with... MORE
I take some offense when they slight our speed. Perhaps not top speed but a warmed up 1275 and a numerically higher diff will embarrass many Porsches and 'Vetts and other expensive and highly respected "sports cars" in the international STOPLIGHT GRAND PRIX. All that and at 1/10th the cost and 10 times the grins!!!!!!! Cheers, Bob in San Diego "Robert D. Gardner" 27234... MORE
Ah, Duncan... You've got an "early" timing chain cover on a "later" engine. Cap'n. Bob '60 :{) PilotRob@... 27200... MORE
Nigel, I may have asked before but where in the UK are you located. If you're in London (which I doubt) you can see what it's like to drive my Frogeye (1275 with Datsun/Rivergate 5 speed) to get you in the mood for your next (vehicular) project. Gary L "Gary Lazarus" 27149... MORE
Hi, Duncan.... The "open" port on the normal stock intake manifold on the '67 is for the rubber diaphragm equipped PCV valve which is fed via a rubber hose from the "flame arrester" (can) fabricated into the timing chain cover at the front of the motor. The "intake air" for crankcase gases drawn out from the crankcase into the intake manifold via the PCV valve is the plastic "filtered" oil cap containing a "graduated orifice" (designed "hole" of a specific diameter.
