Hey there guys, i am new to this forum so i dont know how to make a perfect post yet but i have a quick performance question. I own a Nitro Amax Cheetah and i have a new sort of exuast muffler (not new but got it from another engine) abit like this and when i run it my truggy seems to be slugish but when i unplug the pressure tube coming from the exaust the performance dramitcly improvse, is it bad for the engine or not to do this and how could i fix this?

P.S: sorry for the bad spelling

Sounds like your running rich. Some tuning is in order.

will do high or low needle?

Get the hsn dialed first. Go for good performance, while still getting a nice stream of smoke. Then adjust the lsn for good take off. Leaning the hsn may require richening the lsn, but not necessarily.

If you have the factory settings for the needles start there. As Matt said always do the hsn first then lsn.

+1. That pipe looks like it's off of an airplane. If the engine ran fine before, I'd install the original pipe asap.
