bike problems

Hey guys
Im new to the site and so i havn't really put up any posts. i have a 2003 TE250 that wont run. it only has an electric start but it wont stay charged and wont start the bike. i have had the valves checked by a local mechanic and not a husky guy and he also put a new starter gear on it. he has also put a 65 leak jet in the carb. after all that it just keeps getting worse and worse. i dont know what to do and am at the end of my rope i dont know what to do. if you have any info that might help please reply.
thank you

Not to sound condescending, but you have to follow a simple process of checking things one at a time. Have you checked for spark? Have you checked the carb for clogged jets or a sticking float? Does the motor have good compression? Is fuel getting to the carb? If the valves are way off, it won't start either.
Depending on your mechanical skills, these are relatively easy things to check.
If this sounds overwhelming, then maybe someone here can suggest a good Husky mechanic in your area.

I think the Carb was a Mikuni ??? I thought they went to the Keihn in 2004...

The battery could be beat. It must an '-04 because none were imported in '03.
Can you source another battery? Even one that doesn't fit so you an test that the starter works properly? I have seen the starter gear go bad but the starter itself I've heard no complaints about.

Have you tried jump starting it?
