74 Harley Carb Adjustment
I just picked up a 74 harley 3 wheeled machine and I am trying to tune it up a bit. I had the carb off to give it a cleaning and cannot find any information on how many turns the T handle adjustment should turned out. It was about 8 turns out when I took it apart. Any help would be appreciated.
Thanks |

T handle? Are you talking about the pilot air screw? Pic?

Yes I assume it is that. It is the brass looking adjustment screw.

Re: 74 Harley Carb Adjustment
My ran best somewhere between 1-1.5 turns and you find it is very touchy to get just right. One trick I use to use if it ran better with a little choke it was lean. BUT do make sure the muffler is not plugged BEFORE you start tuning the carb. I had a thin washer cut with slot into the center hole that would slip under the choke knob that I used as a tuning aid. There is an excellent sticky above called "muffler surgery" that shows what can build up in the exhaust system.

You can on page 4 of my 82 HD thread (which I bumped) what one member got out of his muffler
