Well, it fired up by hand after getting it choked properly. What started this is a bad stock magneto set up, so I have only got it started once before. Today I got it started half a dozen times by hand which is what I was hoping for. A big thanks to CH Ignitions. They were friendly as can be on the phone and actually helped me trouble shoot the bad one. They could have just said it was bad and tried to sell me a new one.

Idle appears to be a little rough and too fast. It gets down to about 2400 with a Zinger 16x8 before it dies. Top end is at about 6400 with same prop. Carb is at factory settings. I have an 18x6 Xoar for after a little break in. Running Pennszoil air cooled at 40:1.

How do you really know that you have the timing set just right?? I ask this before I go and start tuning the carb. I checked the thing 4 or 5 times and followed the procedure w8ye suggested. I feel pretty confident I got it right but just curious. I assume you chase the carb all over the place and can't get a good tune.

Thanks
