Ok Here's where I'm at. We reset the timing to 12 deg. BTC. at 900 rpms. The part that seems strange to me is the closer I get to TDC the worse the engine runs. This motor will not run at all at TDC. It like it around 22deg BTC.at 900 rpms. Is it possible when they rebuilt it that they are one tooth off on the timing chain. All temps at the exhaust are in the 300 to 350 range at idle. I will also try the tach. Any ideas? Jack
