I have an Int'l H4 magneto that someone long ago shoehorned onto a Continental F162 (Lincoln SA200 Shorthood welder). I've overhauled the mag, new points and condenser, it is an "L" (CCW) and I timed the rotor shaft and points cam according to the service manual. The magneto sparks like crazy on the bench, and turned at high RPM's (More than 60, counting from the rotor spindle). However, at starting RPM's, which are about 60, there is no spark. Is the reason a weak coil? The impulse spring and counterweights all seem fine, and moving properly. The actual engine timing and all the other timing (governor timing, rotor timing) is correct as far as I can tell and have triple checked.
Thanks for the help!
