Nice plane Lockie, good work! I like the 3 blade prop adds a nice touch.

Thanks guys

Jody I have taken out the choke butterfy and rod because I can choke it from the out side , should I plug the holes on the carb where the rod was are there any issues I should know about pluging them before I do ? I was going to just plug the holes with epoxy so it will only suck air from the stack outlet and not from the upper and lower choke rod holes as well , let me know , Oh and have just spent the last 2 hrs doing the cowl with the dremel still 1/2 way to go ,

cheers

Lockie,

I don't usually use the choke either but I do not remove it. You will have to plug the holes, if you don't it will suck in air through them while you are choking it with your finger and it will be like having the choke only half closed. Would probably be very hard to start cold that way. You could also just put the shaft back in without the plate.

i use this without removing the choke butterfly, and i can still choke the carb with my finger...don't know if it affects performance, but works for me...ken

If you have a CRRC 26 it should have a Torch CMR7H plug from the factory. They are good plugs and give good peformance. The NGK equivalent is the same number as the Torch, CMR7H.

Either one will work fine. NGK plugs have the same number.

C&H and RC EXL ignitions will fire a .050 gap very well, use the TLAR method...
Not sure about the other ignitions, I HAVE run both of the above ignitions at .050, even took the side electrode clean off a BPMR6F, the engine started and ran but missed at high rpm....
I guess if you wanna use the "accepted" gap use .025 to .035....Anyone thinks a few thousandths difference in the gap makes any measureable difference is WRONG...Unless it's on the fine line of being too close....

Ralph is right, the plug gap is not that critical, .020"-.030" is in the neighborhood. I eyeball them all the time and whenever I check the calibration of my eye it's usually around .24".028".

The difference is the heat range, the CMR5H is a hotter plug.
