Acquired a plane with a ST engine...a 2300, I believe. Have not taken it out yet. It was converted to CH Ignition back late 80's. Owner did not have the ignition module. Can I buy a generic module to replace? This spark plug is much smaller. Help! What are my choices if I want to use this engine?

Thanks,
JJ

edit/ I see that you have a gas carb on it

pe reivers

Rcexl has 1/8" spark plugs and ignitions to match.

bcchi

I believe it would have a 1/4x32 spark plug.

I used to chuckle when you said that once you converted an engine, you had to babysit it for life. Guess you were right.

Yes they have. My typing error.

Thanks all. I took the engine out of the plane, and it is actually a ST 3000 with a Walbro Carb and what looks like a 1/4 inch thread spark plug. The aluminum prop drive disk magnet actually bumps the sensor when you turn around by hand after I took the prop off. Not sure why. Is that a problem?

Have not checked on a new ignition unit yet. With this type conversion, can I use my regular 40:1 gas oil mixture as fuel? Any other advice to be aware of?

Thanks guys,

JJ

The sensor needs to be moved back so the magnet doesn't hit it.

Without needle bearings on the rod you are going to need to run 20:1 oil.

bcchi

At least 20x1 10x1 would be better

And I still baby setting some of them at our field.
I still have some ST parts I need to sent to you. Do you want them?
Still same address.

You can not no how little I really care.

Does your ST engine have Throttle coupled timing control?.Does the timing wheel move when you open the throttle.Most all of the RCEXL ignitions have electronic timing. These will work with your engine but you would have to lock the timing plate and remove linkage to throttle.
Adrian at C&H can build you a ignition with out electric timing control.

No it is not throttle coupled. Sensor disk does not move.
