Now that I have porting done It seems like I cannot get the toomey needles dialed in.The third notch down seems to be lean and the forth notch down is to rich.I have read where a few people have had trouble with the toomey[dynojet] needles.I am at sea level running 380 main,stock pilots,two into one uni air filter,toomey t-5s, dune porting,noss head , with stock carbs. It starts and idles fine, I did a WOT plug chop last week ,looking down inside the plug it looks like I might be a little rich on the main,Its a perfect little ring at the base but it looks more brown than tan.Should I try some stock needles?Any imput is appreaciated.

 

Anyone have a set of stock needles cheap?

 

thank you

if you think the main is good and it starts and idles good, has crisp clean throttle response. don't change any think but the needle if 3rd is lean and 4th is fat try the stock needles. 340 main is to lean with a dune port, keep the 380.

I agree with that call on the main. I'm running 340 mains at sea level, 60 degrees, with the other mods in my signature on a stock port. You may be slightly fat, but I would suspect you would be lean at anything around 340. Like the others have said, I would definitely think you should bump the pilot up on, after doing that you may find that the 3rd clip is good for you. I've run the Toomey needle ever since I installed my pipes, and have had no problems getting it dialed in.
