Just set the timing at the spec'd 8-BTDC. It was set previously at 8 ATDC.
I lowered the idle back down to 700 and it seems to run smooth in the driveway. It seemed smooth before but would only run about 37 mph (GPS)
at 4200 or 4400rpm and would take forever to get on plane, always had to ease the throttle to WOT. maybe 10-15 seconds. I hope this fixes it. Anyway, anybody think I should worry when I shove off? because I am wondering why the timing was so retarded. sorry if I ramble, but my first time with a timing light.
