02 350 warrior hard start

[Fiach73]

I am new to the ATV world. I have a 02 350 Warrior that i recently bought. It is hard to start. it has a Mikuni carb which i bought a rebuild kit for and rebuilt it. when you do finally get it to start it runs great, does not bog down or nothing. also it will start easily there after till you let it sit awhile then it is a pain to get started again. can anyone give me any leads? it has a after market exhaust the fmf is only aftermarket part on it that i know of.

Check your compression. Probably low. BTW, welcome to the site and the atv world.
