os vspec engine owners
so any of you all mind sharing your needle settings??? I know no 2 engines are alike even if it's the same model. But it will help me know if i am in the right ballpark. I read the tunnings article that is stickied and it was VERY informative. However it will be raining for a couple days here and won't be able to troubleshoot. My engine totally cuts out at mid to full throtle. I am pretty sure my top end it too lean and the bottom is to rich. My bottom is three quaters in from flush and my top is one and three quaters out. It was running great at the track now the tune is off. I have been making small adjustments and i am pretty close just don't want to get to far off in any one direction. I think my idle gap is 1 mil but i can't figure out a good way to measure it. Might be a bit more or a bit less. Even though all engines are different, letting me here what your settings are would let me know if i am in the right ball park.
tunning is not easy. but i am learning and getting a knack for it.

V spec's tune differently than Italian engines..they prefer a richer bottom and a leaner top, so Ron's tuning tips dont work as well. I am not in front of my engine so I cant tell you my settings right now. I dont keep track I just tune till its good (or someone tunes it for me) Dont tune in the rain. The moisture in the air will give you totally different settings than on a clear day

I know. I am sorry. My biggest shortcomming is patience. Or lack of. But 4 am comes very soon. Just want people to see my tune (vs hear it) and maybe that will help. i really want to learn it myself. I cannot go to the track everytime i need it tuned. It's like 50 miles away.

You need to tune it where you plan on running. Racing on the track is much different than 1/4 mile balls-out runs down the street or doing donuts in a parking lot. There are no "magical" needle settings. I had it setup well for you at the track with it just a little rich on top. You should never have to go far from that.

he is not a employee. he is on the race team. He is on this board and he corrected me. I misunderstood. He made a couple turns (one 30 degree lean on the mid range) and a good 3 quater turn on the high end. It helped alot that day on the track. But back home it stalls at mid to top. I am scared of the mid range needle. And when he leaned it out, it helped alot then but i think my high end is too lean now to compensate for it. Just wondering what you guys have your engines set at is all.

yes.
tell me if my symtoms sound like loss of compression. You heard how my engine was strugling at times. Well its a bit worse now. I still have compression when i turn the engine with the plug in. But can't really feel anything at all with the plug out. I know that could be normal. I also took the P/S out and pushed it up into the sleeve it seems ok. Stop less then a quater inch from the top. It still has some pinch but that does not mean air isn't flowing by the piston correct???. My break in was ok. but it got sumerged in water then i cleaned it. Then it had a air leak found that after i put it back together. I just hope i don';t need a new P/S. It seems no matter how i tune it this is what happens. Wouldn't that be a sign of a shot P/S??
