OT carb question. Honda 4 wheeler

Paul Shuler · Aug 31, 2011

I have a late 90s Honda two wheel drive atv that came to me when my dad passed. I use it almost daily for chores and take it on long trail rides 3 or 4 times a year. It has never given me a bit of trouble. It seems the needle valve is sticking cause when I turn on gas it just pours out at a very fast rate. I have tapped on the carb but has not helped at all. I have never been into a carb newer than my old H or a weed eater from time to time. Is this something a novice like myself can rip into and fix or would I be smarter to look up the local cycle shop and get an est. I Will not go the Honda dealership here. Long story but they are a bunch of crooks.
Thanks,

im guessing it is an old fourtrax. i sold mine because of a cdi box not long ago a 98. those motors will slat forever. the needle maybe sticking because it needs a cleaning most likely. it is probably all full of junk and stuff thats gone through it over the years. it probably just needs cleaning.

I've been into a few of those, but it's been awhile, so I don't remember any specific details, but if you can work on an H Farmall carb, or a weedeater carb, you should be able to fix that 4 wheeler carb. One thing I do remember is that it can be a bit tricky getting that sliding throttle barrel back in correctly, and if you get it wrong it will hang up in the wide open position the first time you blip the throttle.

I think if you get it off and get comfortable and undisturbed with it, a brush, and some carb cleaner, you can take care of it. May even be able to get a carb kit with instructions off ebay.....

A lot does depend on which model you have as to if it is one of the simple ones or one of the pain in the back side ones. Most have a carb drain on the bottom a lot like old tractors and if your problem is from say rust/dirt you might be able to open that drain and then let it flow for a few minutes to clean it out. If that does not do it you will probably have to remove the seat, then the gas tank so as to be able to get to the carb but again it depends on what you have. I do a lot of that type of work off and on all the time on the motorcycles we have up here at the Lake of the Ozarks. Ya not all that far from you

Just got a yamaha grizzly, same carb setup as honda put back togather this afternoon. Neighbor said gas was running out the overflow tube when parked. Pulled the carb, carb was clean, needle valve was good, pulled the seat and the 0 ring was bad. Put in a new needle and seat, $19.98 from yamaha, no more leaks, runs great. Carbs are pretty simple, some will try your patchence getting them off and back on.

I hate to tell you that the carb is likely to be needing replaced. If it is just sticky from setting, you can remove the carb, clean it, and put it back on. If the seat is bad and it won't seal, even if it looks good, even if you buy a new needle if available,you need a new carb as the seat is non-replace-able.

I bought a new carb for mine once, Dad just turns the petcock off when it sets around for more than a little while while shut off. You will be taking chances with another used carb but maybe you can find one cheap. That was on a TRX300 many years ago. Dad still has his.

The tip of the needle is probably rubber and with the new gas its most likely shot. If you want to bench test before re-installing blow into the fuel line and turn carb upside down, the needle and seat should seal and not allow you to blow air into the bowl. They are faily easy to service once you get the airbox out of the way.

If you have to get another carb, measure your two throats and get on ebay. I replaced my 350 + buck yamaha carb with the fancy choke stuff with a new 50 buck manual choke carb. Maybe china work, but is still going strong after 2 years of almost daily use.

Soak your carb with Pine-Sol cleaner after disassembly. Use Brasso and a Q-Tip to clean the brass seat for the needle. That's what we use on 750 Honda carbs.

If you can work on a H carb you can handle the 4 wheeler carb. If I had to guess, its probably got some dirt in it causing the needle valve to stick. Take it apart and clean it, and see where your at.

DeltaRed · Aug 31, 2011

The guys are right,its probably just dirt.Those carbs are simple enough-you can do it!Those old Hondas are bulletproof!I've got two atc 200 (3wheelers)-run the wheels off them-wide open most of the time.they both smoke,but never fail!
