Warmer weather

[twgranger]

With the weather being warmer now do i have to rejet my tri-z? Smaller jet? I was told that when it gets warmer out that it will run richer. It already ran alittle rich when it was cold in the winter. Do i do anything?

You would most likely need to rejet for warmer weather if you want the "Z" to run correctly. Do a pass at wide open and see how the plug looks. it it is black it is too rich. I will usually drop i size at a time till i get a dark tan color. Usually you shouldn't have to mess with the piliot jet too much. Tweak the air screw to get the bog out of the bottom end.
Good luck,
Steve
