Hey guys, this should be my last post on getting this thing dialed in, and I appreciate the help Ive got so far. Heres the situation...
I got my engine rebuilt totally, and it starts up and idles just fine. Problem is, when I took it for a test ride, it doesnt pull on the top end. I can only get about 1/2 throttle out of each gear. It'ss still rev out, just wont put power to the ground past 1/2 throttle. I adjusted my valves cold, but never adjusted them warm yet. I know I need to do that, but before I do, could that be causing the problem? I lined up the valve timing perfect, so I dont think thats the problem.
I added a 12.5:1 piston in my engine, so Im wondering if theres anything special Im supposed to do with this. I set it up with all the stock settings. Am I supposed to retard or advance any valve or ignition timing or do any other out of the ordinary setup with a high compression piston? Im hoping its just the valve lash, but PLEASE let me know what you think. Im a half step away from getting this thing dialed in finally, thanks.
