Went to the local track for some T&T today.
It was bad.
I wanted to try to once and for all banish the off-the-line bog I have when I try to leave at anything over 1500 RPM. So I changed the secondary spring in the carb from the 2nd lightest back to the stock size, and worked from there.
1st run. Couldn't get a decent burnout, but I made the run anyway.
.043 RT, 1.983 60', 12.976 @ 105.41. A little off from what I usually run, but it didn't bog as bad as it had been. So I went to the next size spring and made another run.
.037 RT, 1.875 60', 13.032 @ 103.72. It was better than the 1st run from 60 feet out to the 1/8 mile, but fell off from there.
3rd run. I hop in the car, hit the start button. Whhhiiirrrrrlllll. No motor spinning, just the starter. So I yank off the hood and have a look. The starter had somehow seperated itself from the block. Jack it up, bolt the starter back on.
.009 RT, 1.979 60', 13.850 @ 96.99. It's slowing down. So I go the other way, put in a smaller spring and make another run.
.093 RT, 2.2024 60', 13.951 @ 96.82. The motor was making some really funky noises, when I got back my friend and I were scratching our heads to try to figure out what was wrong. Pulled off the driver's side valve cover and found that one of the pushrods was all bashed up. I guess one of the rockers worked itself loose and was smashing the top of the pushrod. That's bad. So I was only running on 7 cylinders.
I have no idea when that happened, so pretty much my testing & tuning results are void.
Now I need to figure out what kind of pushrods I have, and see I can can buy just one. And I'm hoping the rocker is still in good shape, I didn't really look at it too good.
