I finally made the time to check out the problem. I changed the Holley 1920 to a Carter and accidentally switched the pcv and bowl vent lines. Doh... The vapor line to the tank was getting manifold vacuum.
It has a vapor-liquid separator (4 lines come out of the tank) and no canister. I ran the car with the original cap and a new one. They both had the vacuum hiss noise.
How much vacuum should a fuel tank encounter under idle? I recently replaced the fuel sending unit on my 71 Duster 225 and noticed the fuel cap hissing from vacuum.
I bought this setup years ago based on a recommendation. Do you think the stock coil would have performed fine? Or is a coil from later, electronic ignition a better match?
I have a 71 Duster 225ci and have converted it to electronic ignition. The following diagram came with the kit. After installing it, I was told to change the ignition coil or it would not last long with the new system. I installed a MSD Blaster 2 coil, PN 8202, and the included instructions said...
Even without the modifications, they will still help correct caster. Ideally, control arms with the adjustments built in or with additional adjustments are preferred to the bushings.
If all the starters are the same for that given time period, why is it that parts stores have different part numbers for their starters? Is it just to differentiate and there really is no difference? Also, you mentioned the wiring. Does something need to be changed for the mini conversion?
I have a 71 Duster 225ci and I noticed that after I start the engine, I can still hear the starter spinning, but I do not think it is still engaged (I'll have to double check that). I had the original rebuilt and have put a reman in and both do the same thing (the original is worse). I have also...
