just noticed that your engine has 4 bolts holding the case halves together while mine has only three. you must have an older engine? that separate ignition coil should also work with the CH ignition kit. that's what av8tor1977 did with his little 16cc echo.

what brand of 15x8 are you getting 7400 with?? mine will turn a crappy MAS 15x10 at that speed using the stock 8.5mm carb. you might be able to gain a bit with some simple porting. the "don't forget echo" thread has the numbers.

i've flown an 8lb 60" stick with this engine and performance was great, at 6lb you should have a winner!
