what are plug chops?

..plug chops are performed when tuning a carburetor..

..their purpose is to give you an indication of what your fuel / air ratio is, at any given throttle position..

..the reason the are so important to perform is, you could be running a "lean" mix..which could do some SERIOUS damage to your engine...

..NEVER RUN LEAN!!

..btw, Tutto..I read one of your posts where you said you had white smoke from your exhaust....

..what I found to be true, is that if you have a "rich" mixture, the smoke will be black...

peace

Hey guys, I didn't see the white smoke post, but that would usually indicate coolant getting to the combustion chamber.

If the smoke is white, I was always taught oil was leaking around the ring burning with the fuel. Black smoke is lean. 8)

I have a 2-stroke, always blows a little blue smoke.  If it doesn't I have issues! ;D

..that was always my knowledge..

.. Black = Rich..
....Blue = Oil..2 strokes are a fine example..
..White = Lean..or other issues...

I've read in link from wordslinger a thing that I dont understand in my language ... maybe you could say in other way :-s :

"At the end of your full throttle run simultaneously push the kill button, chop the throttle and pull in the clutch."

what kill button ?

he refers at brake ?

I think that is in reference to doing a plug chop.  You want to push the engine shut off switch while maintaining the throttle position until the engine completely shuts off.
