Please note similar question from kiv and reply from heliair on 10/15/03.
(Looking thru the index-log, I notice some questions are repeated by new
members.) Neat job of trimming crank-case.

Has anyone tried adding a shake-brace from cylinder head to magneto bracket?

Also, I wonder if the magneto and a large muffler would block the exhaust
side of the cooling fins. The flywheel blower and shroud might have forced
air behind the magneto better than the blast from the propeller?

Keep on convert'n!
