Hi Bob, The restrictor inserted in the hose from the oil separator is a modification and not a stock part rather a jerry rig piece of a standard plumbing compression fitting he used to restrict the line, so it was not an official California set up. All I know to do is return it to the direct hose and see how it runs. Although curiosity leads me to wonder why he did it. If I recall correctly in 74 model year the pancake looking PVC valve on top the intake manifold was deleted and the Y connector to the... MORE

Morning Bob, So the collected fumes in the charcoal canister are fed back into the system via the hose to the head cover. It appears there is no collection ports from the fuel bowls on the carburetors. So that would explain their being no hose from them to the canister. That leaves why the PO felt an additional restrictor was necessary, or desirable, in the oil separator to carburetors hose. It was my understanding that as you say "The input fittings within the carbs are in themselves graduated orifices." Think I will take the additional restrictor he inserted out... MORE

Hi, Don May... 1. The missing hose from the carb. to the charcoal cannister MAY be for the fuel bowls with respect to an "anti- runon" valve feature. This is a guess on my part. What this did was create a vacuum at the fuel bowls when oil pressure fell to zero through a solenoid switch when the ignition was switched off. The fuel bowls were vented to the charcoal cannister as part of the closed loop fuel system. The solenoid switch was wired "hot" which is why the PO MAY have disconnected this. 2. The line off your... MORE

I very much doubt if twin HIF 1 carbs were ever fitted to a production car as the philosophy of extra performance using twin carbs had been replaced by using a big single one, by the time HIFs were being used on performance A series engines.This being so, you'd need to find left and right handed individual carbs to make up a set. (was the HIF carb even made in this size?!) You'd do better swapping to twin 1s and modifying the backplate of your filter case to suit, if you're desperate to keep it. David "David Jacobs" 22773...

Once again faced with mystery PO modifications. These have to do with the emission controls. First, particularly on California cars, one must find a proper diagram of the system, something the weak of heart should not attempt from a Haynes Manual. The car in question is a 74 Midget I assume with a stock 1275 First discrepancy . . . The manual, if correct, shows a hose from the valve cover to one of three hose connections on top of the evaporation canister, check . . . that is there. Another hose goes to the gas tank vapor collection... MORE

Nelson... Easier job basically but.... the new Unipart and K&N spin-on filters (and I am sure, others as well) also have an anti-drainback feature which makes cold starts less "oil-less" for those very important initial few seconds after the engine fires....IOW, more immediate lubrication to the parts. Since it is advertised that 50% of engine wear over time ocurrs during the intial few seconds after a cold star...this alone makes the conversion worth consideration. As a matter of fact, this factor is normally one of the priorities for those who decide to convert to synthetic oils, as well.... Cap'n.... MORE

I'm considering getting a spin on oil filter adapter for my 948 Sprite engine. My question is - Is this simply a matter of making the future filter changes less messy and inconvenient or do the cartridge filters do a more efficient job of cleaning the oil than the felt or paper filters?

is it possible to replace the hs 1 1/4 twin carb setup directly for hif twin 1 1/4 and get a slight increase in performance? i already have the marque k&n filter and so want to utilize it thanks Rob "R.Eades" 22761... MORE

"Thanks Bob & Allen for the education" (You owe me big time, Don May!!:):) Assuming it's a stock 1275 you are looking at Don, the correct model of the 45DCOE for the set-up is 45DCOE13. The DCOE is my favorite performance carb. I got mine initially when the shafts of the stock SU's my PO'd '74 started leaking air and needed rebuilding. I figured what the hell and sprung for the 45DCOE tuned for the stock 1275, instead. Glad I did. Worked just fine right out of the box, with the addition of a "deep" K&N filter. Subsequently, the...

I've just cleaned up my '68 midget engine parts prior to putting it back together. I checked the oil separator to see what it comprised. It is packed with very coarse steel wool. I did not note any deterioration after probably 60k miles and I just flushed it to get it ready to go back on Jim Lundgren gztracker@... 22741... MORE

Ketil.. Fires a couple of times: Does this occur more in wet rather than dry weather? Fr'instance, when was the last time you renewed ignition wires, etc. If it is not humidity related but rather temperature related, then amount of "choke" may require adjustment. Consider: Not continuing to run for the initial start can often be a blessing in disguise with respect to initial oil pressure, whether the filter you are using is equipped with an anti-drainback valve or not. Rate of turnover: There is a certain amount of drag associated with starting with the clutch disengaged in the... MORE

First gear is really noisy. The smoothcase uses 20-50 oil only, which is also more noisy. Bob, Troutdale, OR "Robert Webb" 22709... MORE

Has anyone done a diff oil seal change in situ? The haynes makes it sound like a doddle. I figure it will be easier in a way because if you have the rear wheels on ramps then the diff will be kept nice and still to assist undoing the flange nut. What do you think? J. jeremy.cogman@... 22703... MORE
