The 400 is up and running again. I took it back to the shop that replaced the choke and they fixed it again for me, at least they gave me same day service. It cost another 80.00, but at least now it runs.

They were not real sure of the problem. Here is a list of things they told me.

Bad gas
Fouled Plug
Carb Problems

It is running fine now, a whole lot better than when I first got it.

They did say that if this happens again I may be looking at getting a new carb??????

From what they said this carb sat with gas in it so long that they think maybe the air chambers??? in the carb could be slightly clogged with dried gas????

Hopefully this is not the case. B/C from what I gather a new carb would be rather expensive.

thanks

 

Glad to hear that you are up and going again! Hopefully that'll be it for you. I'm not sure if anyone mentioned it before, but it might be a good idea to run some Seafoam through your tank. If your problems were do to old gas, the Seafoam will really clean things out. I use a little on every tank of gas, seems to really work well.
Enjoy your Cat.

 

Yes, try some seafoam. I use Marvel Mystery Oil, I think about the same results and you can get it at Wal-Mart. Also, you could put some carb/fuelinjector cleaner in the gas.

Glad to hear that it is running now.

 

I would suggest running sea foam through it frequently. Gummed up carbs are funny, because once they gum up they tend to gum up quicker from that point on. I learned this with my snowmobile. It was great year after year, then it blew up. The carbs got all crapped up and now every winter before I ride, the carbs are just loaded with crap, compared to almost perfect every year.

Seafoam baby, seafoam.

If they cleaned it good, it shouldn't still be clogged anywhere.


Seafoam baby, seafoam.

 

there you go ,another helped ATVer

 

You may be able to get some carb/injector cleaner in a spray can. Remove the hose from your carb air intake and start your machine and rev it up some and spray directly into the carb air intake. White smoke will come out the exhaust and stink like crazy but that is normal. This may help clean out any gunk in your air passages. (If your engine is not rev'd up enough it may stall).

 

ok back to the issue. ther is a problem with the auto choke cats that is getting very common. they need 12 volts to operate, if they don't get it they don't work. the stater that is involved in the process is the problem,..they are failing left and right not allowing the choke all the volts. hope this helps you and your dealer fix that problem.
so basicall have the dealer check voltage at the choke,..that will get them on the right track.

dont feel too bad, mine has been in the shop for most of the time i've owned it,(1 year)..but im givin them this one last chance to get it right.

 

While your atv has a problem, it is obviously nothing compared to the problem you have with your dealer. I've read your other posts and its really too bad you have no alternative dealer you can get to easily.

 

For starters, I'm sorry to hear you are having problems. My suggestion would be to try a different board, this board seems to me to be more novice oriented. arcticchat.com and highlifter.com both have some very knowledgeable and helpfull people. Oh and usually less bashing (usually)! Typically engines need 3 things to run: gas, air, spark. It sounds like you have spark. Have you tried some seafoam in the gas to absorb any water? Not having an ATV yet i can't answer to the air gate you are talking about... I'd look deeper into the air / gas issue. Oh and it is always a good idea to repalce the plug. Even if you get a spark sometimes replacing the plug will do the trick. On that note, what color is the plug? That can help diagnose the problem too....

 

Even being NOVICE'S, I believe that most of your suggestions have already been mentioned. But we would like to thank you for your input and sharing and come back anytime. "You would be supprised what you can learn from a dummy." If it were not for dummies we would not have seatbelts would we. lol.
