Questions Regarding Older Zenoah Engine
 

Hi guys, I need some help with figuring out modification on a Zenoah 3.70 cu in Quartz I got from someone who didn't know what type modification it was, anyway here are some photos of the engine, can somebody explain what the modification is, Kill switch or ignition?;)

Whats that red plug for???;)

That is a Ralph Cunningham G62 light conversion, you will not find a better engine anywhere than that one.

The plug on the side of the cup mount is for the power to the ignition.

Can I get an after market Ignition for it BadAzzMaxx? I think I struck gold here, this engine has so much compression it wants to wring my wrist whenever I turn the prop shaft, very good engine, yes sir.

RE: Questions Regarding Older Zenoah Engine
 

Yes, But is the ignition on it not working.

I did not get one with the engine.

Ralph is called Antique here on the forums, If you have a problem with that engine I would contact him, He knows that engine inside out.

I do replacement carry ignitions if you want to go that route.

That is it you are looking at in the cup mount, Just get a connecter that fits the red plug on the side and it should work.

Is CH ignitions still in business, where can I find one???

RE: Questions Regarding Older Zenoah Engine
 

Ok I got that, if I get the plug where would I attach it or what would I attach it to??

RE: Questions Regarding Older Zenoah Engine
 

No CH has closed for now, But again, Hook up a battery to the red connector on the side of the cup.

The ignition uses the existing Zenoah coil and the electronic board in the cup mount is what fires it.

I see that you sell replacement Ignitions, cool, do you sell any for this engine??

RE: Questions Regarding Older Zenoah Engine
 

Ok BadAzzMaxx, this is very helpful information, I will try what you've just recommended.

RE: Questions Regarding Older Zenoah Engine
 

??????

Why do you want to buy a ignition when you have one that should work.

To use my ignitions you have to remove the one in the cup mount, Remove the existing coil and then install a connector to the sensor lead wire.

Pardon me BadAzz Maxx, I wasn't sure what the circuit was, but I will hook up a battery pak, is 4.8v pack fine to use??

RE: Questions Regarding Older Zenoah Engine
 

Yes

RE: Questions Regarding Older Zenoah Engine
 

Unless I'm badly mistaken that's the ignition inside the cup mount at the rear of the engine.

First time seeing such a setup Karol.

RE: Questions Regarding Older Zenoah Engine
 

Back then it was one of the best setups you could ever get. Still is too, including the engine conversion.

Karol

RE: Questions Regarding Older Zenoah Engine
 

It's one of my old conversions...If the ightion doesn't work send it to me, it's guaranteed...

RE: Questions Regarding Older Zenoah Engine

RE: Questions Regarding Older Zenoah Engine
 

Ralph is de best.

Karol

RE: Questions Regarding Older Zenoah Engine

RE: Questions Regarding Older Zenoah Engine

Very neat idea, when I first got the engiine I was uncertain what the heck the setup was, was it a kill switch or ignition, found out all about here on RCU, thanks alot guys, all inputs were quite helpful.
