MHM-didn't they used to have an extensive engine line similar to 3w? now i only see a couple ryobi conversions on their site, shame.

i use a tach and i can move the sensor all over the place without a change in speed, even at idle, so i'm thinking that my magnets might be too strong. i also get a spark even with a really slow flip, from what i've read the 3w needs a fast flip to spark.

next engine will have a smaller magnet
