" I have a 1978 Chris Craft with Q model 350's. My book tells me to time the engines to 10 degrees. All I see on the Forward mounted Flywheel is an "R" with a Slight "dimple". I'm used to seeing degree marks on a harmonic balance. So with no degree marks, what do I do? I was told one flywheel should have the "R" and the other should have an "L". Is this true? Both of mine have "R"'s on them. Is the dimple my 10 degree mark or is it zero? Thanks for any help! I just rebuilt one of my engines and want to avoid destroying pistons like the previous owner did. Also, if that dimple is my mark, could something be wrong? I timede the port engine to the dimple and when I shut it off, it won't restart until I advance the timing. Thanks for any help!!!! "
 
I had a similar problem. My distributors on rebuilt engines were 1 tooth off. My flywheels have multiple holes drilled not just dimples. With the timing at TDC the engines would start easily but flood out at load or when they warmed up and would hit the wall at around 2,000 rpm backfiring and bucking. I found two adjacent marks barley visible together in the timing window. One is TDC and the other is the recommended advance. I confirmed this with this timing light which has a dial on the back that retards the light not the timing. When you find the TDC mark the dial tells you your advance. I have 1 Mallory electronic ignition and a newer replacment wgich noone can tell me how to adjust the advance or where it should be. Hope all that helps
