Hey FlipFlop,
Are you running the syncro spark? or Fixed timing version?

I just got my 42 outta my saw this morning and ignition on the way from CH tomorrow.

CH hasn't tested the 42 yet...so they are sending me the 33cc version full conversion kit prop hub, igntion, sensor mount. I can use on my 34cc motor if it doesn't work on the 42).

Is the 42 a different cylinder than the 33/34cc?

I may need to somehow make a sensor attachment bracket like yours... Do you think I can do it without a bunch of machining tools? Basic dremel, drill press and hack saw?

Thanks,
CrazyHerb
