Choke cover leak - help!
Posted: Thu Nov 21, 2019 11:25 pm
So after 3 years of chasing an idle and low RPM issue, I got to the conclusion that it was related to a lack of fuel at that rpm range. Lack of fuel meant no power/stall until rpms reach 1300-1400, then all normal.
I managed to eliminate the stall by pulling out the idle mixture screws way out of range, about 2 to 2.25 turns out, and increase my idle fuel jets to 60 and decreasing the air restrictors (jets) to lowest.. I believe 110.
But winter came and symptoms started to show just a little, and I hate the smell of such a rich mixture. So I went again on the chase for a vacuum leak. Spraying all type of combustible gases and fluids did not help. RPMs never changed enough to recognize a leak.
So finally today I went with the other leak detector, the smoker. And... surprise! First, I thought my carb shaft/bushings were ok, well all except one that likes to smoke. But the real surprise was the smoke coming out of my choke covers. I changed the paper gaskets recently but obviously this must be an uneven base or cover.
Anyone with experience with this problem and what is the best solution?
