It there a replacement for 3w single cyclinder motors. I have trouble the the 200.00 price tag. John

i believe CH ignitions makes one...from what ive read.... they produce a hotter spark than stock 3W ignitions and are reasonably priced

Spark is about the same. The big difference is they always work.

True(BCCHI).

I've converted both of my 3w-50i's to RC Excel ignitions. The ignitions even come with a bracket and sensor that should work. My engines have the newer two magnet setup so if it's an older engine you might want to go with a "universal" mount from CH. I've got two working 3w ignitions I'd let go for a good price!

If you have the two magnet 3W it is a plug and play conversion, Just set your polarity to the gray magnet and time it. Only tool needed is a screw driver.

If you need help timing your engine, go to the link below and click on the link for timing you engine

Some people have said that the 3w has more power with the timing set at about 32 deg before top dead center.

If you have the older style you will have to drill and retap threads to relocate the sensor, Secound picture

You need to use sensor braket number 3 in the picture below

I have the new style 3w-28.. This is great news!!!! Thanks John

Anyone know if these ignition will work on my 3W80XI. and if so what one do i order.

The one for the CM6 spark plug...The RC EXL ignitions are otherwise the same..
