Color Tune?
 

Can I use a color tune on my rotary engine?

I'm thinking about buying one anyway, but I just wanted to know if it was possible to use it on my 7.

Seems like the leading hole is big enough to look through. I know the thread depth is adjustable (and I'd turn the engine over the first time slowly so I'd know if it was gonna hit apexs), but would the color tune plug end provide enough ignition to fire the engine properly?


Also, I don't know if I have enough room between the frame rails and the engine to fit the device.

I'm not sure how accurate it that would be on a rotary. The design is inherently rich in terms of unburnt fuel, hence the need for secondary spark. If the color tune is measuring before the 2nd spark, will it be accurate?

Not only that but if you read the reviews after googling around, it sounds like its not that good
of a product and may damage the sprak plug threads in the housings, since our housing are
AL like motorcycle heads.
