okay, I am new to PHBG, so be gentle. I've read the wki and done a search, but I can't totally find what I am looking for.
19 DELL Racing Carb, 90-92 main jet (been testing, 91 in there right now), 7 needle second clip, 60 choke, and not sure what the idle jet is. I have a 42 idle down at Treats that I need to pick up and put in. This is on a K-star case matched, high comp head, race clutch, etc. Pinto.
The bike seemed to run great with the 92, but I would come to a stop sign and the engine would rev way down, like it was gonna die, but it didn't. I screwed the idle in all the way and that didn't help, so I started messing with the air screw and ... that's when things went wrong. And it hasn't been the same since. Basically, it drives awesome when I first start it up and starts right up from being cold, but once it is warmed up, I have problems. The revs go way down at a stop and if I stop revving the motor, it will die. And then it is REALLY hard to get it started again. (no pedal chain, so I have to push, so without a hill it is super impossible to start again).
I am gonna try to go down on the idle jet, but I am wondering if there is a stock setting for the air screw (like turned in all the way and approx how many turns out)??? Just so I can get it back to stock.
The bike is running a bit rich and the plug is getting fouled, which I imagine is why it is hard to start. I am going to try going back down to the 90 (went down to the 91 today, but that didn't help much). And, yeah, I need to get that idle screw changed. It just is not running well enough for me to feel good about driving down to Treats. Thanks for any help and sorry if I am missing easy to spot tuning stuff for the PHBG. I am a total noob. I was fine with the SHA, but this is definitely breaking me in.
