Ok guys looking for some help! I recently traded my honda civic for a honda 4trax 350. I know the guy I traded he bought it new. It sat up for a bit but before I got it from him he put on a new carb and fuel pump changed oil put a new battery. I got it and it ran ok for a couple of days woke up and it wouldn't crank so I cleaned carb checked everything I could think of and it ended up being the spark plug I tuned up the carb and it's running great sounds like a new quad. The problem is it seems as though it lost some power. Before in first gear of u hit the gas the front end would pop up and in second and third if u let off and hit the gas you could feel the torque. Now it seems to be significantly less but it sounds a lot better. Any ideas??

fuel pump oem ?, if not..is it working like it should ?. never seen the front come up on these models , unless your opening throttle wide open, and putting it in gear ?..if so ?..not smart !. these are not a sport atv by a long shot !.

I don’t think these have a fuel pump, but they do have two oil holes:?

Ethan try downloading the service manual for your model; that will be a good start

Sorry for being a little vague guys I've only had the quad for 5 days havent really had the time to take it all apart. Its is a 2002 honda 4trax. It came with the original book I was told all of the routine maintenance was done as well as the fuel system was all cleaned out and a new carb. I just assumed it had a fuel pump because my Polaris does and that's the only quad I've ever owned. I know this is not a sport atv I got it for hunting. And no I didn't mean i was popping it into gear to make it pop up. Sitting in first gear at a stop it would pop up because of the torque (there's also a very sturdy welded rack on the back which may play a role and I was on pavement with brand new back tires) but after taking it out today it has definitely lost power somewhere I couldn't get it over 20 mph going up a very small hill or even spin a tire in first gear on sand. The only thing I changed was a spark plug (the same exact one)also has new air filter any ideas? its definantly not pulling a deer out of the swamp the way it sits

 

[shadetree]

then you have a trx350 rancher. they dont have fuel pumps .

 

[shadetree]

is the carb oem ?, or some china junk from ebay or amazon ?. if its china junk ?, then thats where you start !, put the correct carb on it ( oem ), and then we'll see what we got.

HONDA TRX350TE/FOURTRAX RANCHER 2002* is what it says when u type vin on google but the book just says trx350te fourtrax so that's where the mix up was but anyways not sure on the carb probably a amazon special from the looks but like I said its clean as a whistle and the power was fine the day before. I was told the choke didn't work. the boot going into the carb is stripped and spring isint much of a spring anymore I'm thinking this might have something to do with it? Considering that's the only other thing I touched besides the carb and spark plug.

Alright now we’re getting closer. Take a look at your carb; there should be a number on the side VE94ACxx maybe. If so then this is the OEM carb.

Use my links to find your carb and parts. If it needs a starter valve that could be a good improvement

 

[shadetree]

prob a china carb ?, yep..choke enrichment valve is not working...so this will cause all kinds of problems .

The throttle and choke cables don’t fit an aftermarket carb very well.

I hope his carb is OEM because that problem would be easier to fix.
