Hi - the '75 DJet car has a stumble that happens at a couple points in the rev range and at certain RPMs when the throttle is held constant. It rarely happens when the throttle is being exercised up/down the RPM range (like accelerating through turns etc).
I'm thinking worn throttle body "fingers" or the trace pad they travel against (yeah, wrong terms I know) but I believe this could also (maybe) be a sticky advance weight in the distributor. Any why to test the spare throttle body so I don't swap out the wrong thing? OR Should I just pull and open the plastic cover on the one I have to see what is up? Doesn't look that hard to remove it. What say you gentlemen, and please do liberally apply terminology dope slaps. Thanks! |

Thanks! @Tdskip the stumble is either just loss of contact due to dirty contacts or wear. you might just have to clean off the contacts and the board, the board will clean off with an eraser, it will look like its worn but might not be. But if a new board is needed replacements are available, Dave Sprinkle makes them and 914rubber carries them. then setting the alignment of it is pretty simple. Phil |
