fixed float level, but still have problems
I found that someone had screwed in the float level screw way to tight. This deformed the little bent metal piece that adjusts the pivot point for the float. Fixing that, and an hour of idle mix adjustments, removed 90% of the carb-popping.
I have had no luck removing my remaining small carb-popping problems, and a backfire from the tailpipe in throttle transition (up and down).
I find when I screw #1,2&3 mix screws all the way in, one at a time, the idle speed slows as that throat gets no fuel.
Screwing #4 all the way in, however, has no affect on the 1000rpm idle speed. How can this be?? Where is #4 throat getting fuel? The idle screw is undamaged and the main jet is clear.
Has anyone had a problem like this?
