I have finally gotten my trx 2.5 to beable to run through a full tank without overheating 2 times not. Unfortunately it takes till almost 1/2 tank before I get it adjusted where I have great pwer and it doesn't bog or stall. Both times I thought I had it tuned perfect I would try to start it the next day and it would flood and not turn over. After I get it started it is so rich that it spits fuel and stalls when I give it any throttle. I have to lean it out on the HSN when it is 1st started then after a few minutes richen it back up. Does this sound like typical worn piston and sleeve symptoms? I bought it used with a suposed new piston and sleeve and I did the traxxas break in and I have about 1-11/2 quarts through it.

Sounds like u need to ajust your LSN and idle screw

Thanks do you think I need to lean the LSN? and raise the idle? Or lean both? All help would be appreciated!

U need to lean the HSN, LSN, then the idle screw in that order.

make sure when u adjust the idle; that u adjust it so that there is about a 1.25mm opening when u look down into the carb barrel when its at the idle position. Or about the thickness of a credit card.

and after every adjustment make a ferw high speed passes to clear out the carb and to see what the adjustment did to the performance.....thats the best way to learn tuning.
