Having trouble starting my fire evacuation saw. This is a high reving old saw. When I try to start it seems to grab the starter and refuse to fire. Suspect fuel blockage or ignition problem. Does it help to remove rust around magneto fields on two stroke solid state ignitions. Is there a carby clean product that helps unblock fuel obstructions, eg. fuel gel, blocked fuel screen, jets etc. Is it safe to use ether, propane or butane to start these small machines?
Regards, Gomower.
