Hi
one week ago,last Sunday I make my firsts flights with my Weedeater, nice engine, 3 flights with more than 35 minutes accumulated.
Diablo is right , no interferences, but for extra care I added a coax shield twisted over the High tension lead, my spark plug is RCJ6Y, this came with the engine.
I am reading your posts and learning, very useful.
Many Thanks Diablo and Rysium

Diablo
Do you think to dremel the wall between both transfers to make only one big transfer?
I have seen a transfer like it in a Zenoah G26 and I believe from photos the only one transfer have near 25 to 30 mm wide.
Many thanks for your time
Jose
