Roscoe,

There was a decent piece of baffle needed in the front left, which I think helped. It went from hard to keep the temps down, to more just watch and manage them. Yesterday on a fairly hot day, 1/2 were in the 360s, 3 was in the 380’s and 4 was just short of 400. But it had an occasional sputter at high rpms, and ran rough in mid rpm, making it seem like it wanted to be leaned. I did lean it to smooth, but went back richer to avoid a heat increase.

I’m not even sure if the LASAR mags are bad. I need to find someone who can troubleshoot them, or time them if they are out (this was a hunch by Keith Hetrick, he thinks timing might need tweaking). If it was just the overheating, I would be redoing all my baffling just to make sure its perfect, but I don’t understand why it runs rough in the mid RPM range, any ideas? Carb?

Do you know of anyone in the Kansas area, or around Kansas who knows how to work LASAR Mags? I really would like to check them out and eliminate them as the possible issue.

Who in this area would really know baffling for Grummans?

I’ll keep you in mind for if one of the parts is bad! Better than replacing the whole thing.

Thank you,
-Clay
