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!
