I am 15 years old and i dont really have alot of money. []

Im building an RC boat about 54" long with a 25 cc homelite weed eater engine.
Is there anything i can do to the engine to make it run better but at a small cost?

thanks

You can make a piston-cut mod, search the net for pistonmods for 2-cycle engines. That, and a tuned pipe will get you a far bit on the way...

First thing before doing any internal work , get yourself a tuned pipe and a larger venturi carb ( but do NOT go over a 12 for the venturi and also get a WALBRO . They sell them on the BAY all the time . ) Also , although not bad .... but try to avoid ones with chokes on them . To choke your engine , simply "thumb" it for a pull or two .
Then , after you have done that , THEN you can think about doing some cutting .
The easiest cuts are the intake and exhaust manifolds . Cut the upper area and sides on the exhausr and the lower and sides on the intake . Just do NOT take a LOT ...
THEN , you can cut into the transfer ports a little ....
( Dremels work GREAT for this cutting )

Yep, the pipe is of course the easiest way to go. Next step would be to cut the piston, in my opinion. If you mess up the piston, it won´t be as expensive to replace as a complete cylinder if you decide to mess up the intak/exhaust/transfers. It´s really hard to mess up to. On the intake side of the piston, right where the intake openening is, take away just 2 mm of the skirt in the piston.´If you don´t understand what I mean, just let me know, and I will show you a pic.

Take a look at www.shark-racing.com , lots of info on how to treat homelites (a.o.)
