Just did the top end rebuild and thanks again for all your help!!

I have a question though.

compression test: re-rung drive side=120lbs, fan side w/.020 oversize piston=130 (you guys are good). I started the sled and it seems to run fine. But after letting it run for 5 min at idle and took it for a short spin, I put a temp gauge on each of the cylinders, the fan head=80-90 deg and the drive wheel head = 160-180 deg. Does the fan cool that well? Are these temps normal?

the temp gauge is a professional laser thermometer used in heating and air (thanks to my bro), so those are the temps.

I do have spark on both wires as far as the inline tester can show. What little snow we had this morning, I was able to run it around the yard a few times. Snow is gone in chi-town area now. Seemed like there was enough power, but I cant rev it up yet until snow comes back and break-in is over.

I know I sound like a mother hen, but I don't want to do this all over again. :(

Thanks

Base your worries on what the plugs look like. Are they a dry dark brown or are they black and oily? Or maybe even a light tan to white? You want the brown on both sides. Judging by the name you are the resident computer Guru?
