Well, we went out saturday and my guy was going for the pass to win the feature but the guy seen his nose and pushed him down and spun him out...guess we should have gone by him faster.
I did find a problem though. I checked the timing at 3000 and it was right on 34 (proven at dyno) I then reved it up to 3800 and the thing advanced to 48! Its a brand new DUI installed at the first of the season. I swapped it out with another new DUI from another build and the thing held its total timing at 34. It had total timing at 2700 and held it there even at 3800. I though great1 Theres our problem. Too much timing after 3000 (since thats the RPM I always set my timing at).
We fixed the fuel filter backwards problem and I cleaned the 4412 carb and also installed a new Stage 3 stewart pump along with the new distributer.
I kept an eye on that stupid yellow overheat light as he went by and at lap 15 it was on! He came off the track after the race was done a little over 230. Damn thing.
A new symptom though. At mid to end of track the engine had a miss in it and it was popping now and then. We didnt lose any water.
Im thinking we are running out of fuel which is causing a lean condition. I also jetted his carb up 4 points! 76's turned into 80's. For last nights race. We always ran cool with 76's
I checked the plugs after the race and we are still lean in the back or getting too hot.
Im going to try checking the timing with another light before changing out the fuel pump. (Thanks to Dave at Propower)
