Take the carb off and check the transfer slot. it should be exposed 'square' to maybe twice that (the book will explain it), if not, get it right and adjust the secondary butterflys by the amount of the front (ie 1 turn close on the front, one open on the back). Set your float height (up till it drips, down till it stops, that is max, do down from their for tuning). Set your idle mixture, adjust your accelorator pumps. Call me in the morning  |
Uhhh how about the main jets???? They are the key element of performance tuning. All this other stuff is just carburators 101.
