well i am not sure where to turn i have been trying to get a hold of someone at bme. i have been calling and emailing now for over three weeks with zero return call or email. all i need is a hall sensor which makes number three on this motor in like 2 years. i would sell it if it did not run so well. can anyone tell me where else i might be able to find parts for this.
thanks

C&H Ignitions sells the pulse switch if it has a C&H ignition. You will have to JB weld it to the bracket. Just bought 2 for my BME 102s

outside of the obvious how do i know if it is a ch ignition?

Most of Keith's BME engines used C&H...There were some with Falkon...If the 3 sensor wires are red, black, and white, it's a C&H....
And the box should have the name on it....Old C&H, brown box, yellow letting...Later C&H, aluminum box....VERY 0ld C&H, brown box with pop rivets holding it together..Replace it, the igntion is not syncro spark...

I've got a BME 44 and 50. Both have a C&H ignition. They are clearly marked on the ignition.
