My 300 fourtrax is having to be choked to start and choked to stay running, and once I push the throttle it dies almost every time, and when it doesn't die it seems to be quite delayed in its response, like I let off of the gas and it is still obviously getting gas for a few seconds.
I just installed a carb rebuild kit, drained the gas, put an inline fuel filter on and a new air filter and I am getting the exact same results.
after searching through the forum I've come across two things that caught my attention. @ http://www.hondaatvforums.net/forums...uote=1&p=71158
shadetree talks about the premier being torn up on the carb can cause a vacuum leak.

yes..rebuild that..it will not only cause a fuel leak ( just done one of those )..but it will cause a vaccum leak..in other words..your carb won't draw fuel from your bowl right..lol.][/QUOTE]
I'm pretty sure (not at home right now) that the rubber part on mine does have a small hole in it, and I recall the premier not really having any sponginess to it when I pushed it. Can I somehow rig this to test it? like wrap it tight with electrical tape just to test before I buy the $90
replacement kit for the premier
Another thing that caught my eye was the 2 1/2 counter-clockwise turns from being tight on the idle jet, I need to adjust mine because I know mine is not adjusted this precisely, could this cause the atv to die when not choked?
