Not Ranked
I am a little disapointed in the whole dyno tune experience. When I talked to Eric he indicated that the process usually took about an hour. In TWO hours of dyno time the only thing that was accomplished was to rejet the carb and set the timing. Played a bit with the accelorator pump but did not have the parts to get it right. I have to finish the job myself.
Since I have been there the car will now backfire through the carb abit, I think it blew the power valve plus I suspect the timing was not locked down and has slipped. So tomorrow I am going to go through it all again and if what I suspect is correct, then Eric will be hearing from me.
No adjustment at all on power valve, idle mixture, transfer curcuits, secondary springs, NOTHING. Usually takes an hour 'eh?
They did get the fuel curve at full throttle right. Car picked up a bit of power from the first run. Of course they backed the timing off SO far that it lost power from the start.
Not pissed yet. We will see what I find tomorrow.
