Carb problem 2007 Honda foreman 500 4x4 es

[Ejwill]

I put a new carb on my trx500fe which I have done before on other models, but this foreman was a real pain, takes forever to get to the carb. Anyway I got the new one installed . I also changed the choke cable while I had it this far. When I turned the gas back gas started running into the air filter box. I did have trouble with the choke cable, it didn’t seem long enough to run where the old one did and the elbow that came with the new carb had more of a 90 on the angle. It didn’t feel like it was binding but I don’t know if the valve was seated on the valve seat. The choke pushed in smooth but who knows what happened in side the valve body. I don’t know if this could be the problem or not I hadn’t run the it just turned the gas back on. Appreciate any help, hint, hint Mech and GW or anybody else. Deer season is over in a little over a week. My power chair won’t make it down those muddy roads. Thanks again.

Hi. The float needle will be stuck a little open. Well unless there was some dirt in the fuel fitting before the carb went on. if it's just a stuck float needle then a tap fairly hard with a screwdriver handle, done with the end of the handle so it's got some force, and right by where the float needle seat is going to be, quite often cures that. Or you leave the tap off, wait for it to dry off a bit then start the engine, run it till it starts to sound like it's getting low on fuel in the carb bowl, then turn the tap back on and keep listening to the engine while you keep it a bit above idle revs. If it starts to run rough and belching smoke then the float needle's still leaking.. probably got a bit of fluff on it. To be real sure before pulling the carb off again I'd repeat both those things again.. Or even run it right out so the needle drops a long way down, then turn the fuel on hoping it flushes a speck of dirt out and lifts the float and needle better this time.

Thanks Mech I actually went ahead and removed it before I saw your reply. The float valve seemed to be moving freely. I wasn’t sure if I needed to do anything to it now that it off. Everything was already off so I just pulled the carb and took the float bowl off move the float and turned it so the float move the valve itself. It appeared to move freely. I guess I can just install it again and try what you said. I wish I had seen your post sooner. But it wasn’t that hard to remove at this point.

You can test them while you're holding them in your hand by blowing into the fuel fitting while you slowly tilt the carb in a way/direction that will make the float slowly swing from it's hinge at the top, towards closing the needle onto it's seat. You have to hold it so the float's hinge is going to be at the top. It should blow through freely when the floats hanging away and block off entirely when the float is hanging even just lightly against the needle.

I did like you said blowing in the intake it leaks by. I may just clean the old one and put it back on. Unless you know of something else I can do. Thanks for your help.

Mech, I took the float off the new carb and took the jet out cleaned it and blew air through the valve opening. Put it back together and tried it again like you said this time it worked. Must have been something in there like you said. So I’m going to reinstall it tomorrow sometime and will post how it did. Hopefully that got it. Thanks again for all your help back on the 350 and now. You’ve been a great help. Thanks until next time if this works. Will let you know. Jeff

If I was you I would try to clean out the old one and try it and while you do compare the two to see if they are an exact match.

[Ejwill]

Ok thanks, I may give that a try. This new choke cable is giving me a hard time. With the elbow and nut on it there’s not enough inner cable to connect the plunger to.

[AnthonyT]

Is the new choke cable OEM?

[Gwbarm]

If this is a new aftermarket carb they are not allways a perfect fit you may have to adjust the cable to get the length you need or shorten the elbow. Is this also an OEM cable or aftermarket.

[Ejwill]

Yes oem I’ve got it installed now seems to work. I thought the metal 90 had to go in the rubber one but I left it out and got it to work. Hope that was right. Working on removing the clutch housing cover to replace the clutch adjusting bolt. It had the wrong nut on it and threads were stripped. When I finally got it off the adjustment bolt was really hard to turn, I had to use channel locks on the screw driver to get it to turn either way. Got it to turn and now it turns too freely and it gone just about into the housing. Starting to remove the housing cover knowing I have to replace the bolt and possibly the lifting plate, hope everything else looks ok. Was hoping not to have problems with this one but was wrong. My wife found it and wanted to get it so I hate to keep sinking money in it, but it’s the thought that counts. I’ll keep going till it’s fixed or the money runs out. Thanks for the help, I sure need it. One other thing I’m trying to find parts and having a hard time on several sites I can’t find my atv. It’ll have a2007 trx500fm but no trx500fe are they compatible as far as parts? If not don’t know what to do. Found one site that had 2007 trx500fe but everything I look up it says will not fit your ride. A few sites have trx500feA or A2 don’t know if they are the same thing or not?

Have a look here with your frame number ready and you will be able to tell if you have an A or 2A..
