UPDATE !
Okay, she is all back together again. It took a little more time than expected. Heres why.
As I said. Ordered new heads, coils, starter, seals, yadda yadda. I had also ordered a new kill wire assy. I installed everything, double checks clearances, air gap etc. The engine fired right up..ok great I thought. Well, still no power. First thing I thought of was "oh crap! Lew asked me about the cam" but I measured it and I had both cylinders the first time I put the new push rod in it. The pto ran and all. So, I started checking spark. Had good spark. I pulled plugs. Uh oh! One wet one dry. What could this be??? Pulled then engine again. Took off blower housing. Air gap still good. Not sure why I thought to do this but I pulled the kill wire and ohmed it out. One side "while connected to coils" showed open. The other side. Closed. Brand new kill wire from briggs with one defective diode. So anyway. I got her all back together. Fired up! BOTH CYLINDERS! YAY. So I cut the front grass hood still off just in case. Ran terrific. Lots of power. Very very happy!

PS, I should add. the thing that brought me to the kill wire was that when I shut off the key the tractor hesitated to shut down. The fuel solenoid is what was shutting it down. The kill wire had worked before all the work was done.
