Had one recently that almost made me change careers, customer
brought it in saying it bogged down when you gave it gas. Also
said he put a new carb kit in it, which with a Bing carb, is very
expensive. I took the bait, figuring I could easily figure it out.
I went through the carb, all looked good, except for some
boogering at the high speed jet, which was from a failed attempt
at removing it, so I replaced the jet, which did nothing. Full
teardown and crankcase pressure test revealed nothing. Saw
started and idled perfectly, just bogged down when the throttle
was applied, no matter where the high speed jet was set at.
The inside of the carb was clean, perfect. I was ready to throw
in the towel, which is not easy for me to do.
I took the carb apart one last time, grasping for anything.
I looked at the area under the circuit plate, and noticed that the
gasket holes did not totally match the plate, and that was it!
I got out another kit{the correct one} and the gasket was
different from the one in the carb. The customer bought the kit
from another dealer, and he must have sold him the wrong kit,
so I was left to figure it out. Why Bing would have 2 different
kits that were identical except for a tiny variation in the size of
a hole in the circuit plate gasket is hard to guess, but I wasted
a lot of time figuring it out. Bing is an obscure carb maker
anyway, so it is by no means a common problem.
