From what I have read the exhaust effects the carb.Im trying not to buy a bunch of different sizes of jets and where do I get he plastic washer?
Some backfiring is normal, so you may not have any problem there.
Is it running bad now ?,....you never did say. If not, why are you just itching to hack the carb,.......probably for no reason ? Do a plug read, and go from there. You said the idling improved when you adjusted the air/fuel mixture,....thats good.
You better have a dial calipers when you start playing w/ the white spacer. It is a critical adjustment,....and also one that may not be needed.......unless you have a lean spot in the low to intermedieate throttle range.
