Throttle / butterfly shaft vacuum leak
Posted November 28, 2011 - 10:26 AM
I found a vacuum leak on 1-2 & 3-4 throttle shafts.
I found the felt seals and replaced them:
The 1-2 leak disappeared, however the 3-4 is still there.
First off, the throttle shaft rides directly on carb body, no bronze bushings what so ever. Also, I think these felt seals are a joke. The body & shafts seems tight with no major play.
I'll try to open the idle mix screws on problem carb one turn.
I also may try to ditch the felt seal and put in some o-rings.
Anyone else have this issue?
