Denny,The timing is off got to put the timing tape on to check the advance. The initial timing is set on 10 degrees. I've made a few pictures but can't figure how to down load or paste to this site. I don't know if it makes a difference but I run Evans coolant with flowkooler water pump and march high flow pulleys. It take the engine about 15 minutes for thermostat to open on 80 degree day. Thanks Leon
