912 mag drop

[gasguzzler]

I have a problem on my 80 hp 912 motor where there is a serious mag drop on the left mag which gets worse to the point of a back fire when the engine is hot. I don't know who to contact that can come to the field ( Circus near Henley on Klip ) to fix this problem. Any advise or contact no.s greatly appreciated.

Contact Gideon!!

The first place I would check would be for a loose wire on a mag switch or faulty switch.
