I have a 1987 Honda 250 Four Trax 4 cycle.
It acts like its getting too much gas and flooding out. It leaves the plugs Black and fouls them out.
Where can I buy a replacement carb?
I need to take to Honda place and get it rebuilt.
They said it probaly needs needlw replaced....
What do you think?

 

storm5, why dont you buy the kit from Dynojet and do it yourself, they give full instructions, and it takes about a half hour to do. Or so they say.

 

Just check your fuel mixture screw. The dynojet carb kit is NOT a rebuild kit.It is a performance kit with a bigger jet and float neddle which means you would get more gas flow with it than you are getting now which would cause more plugs to foul.

 

Bigbear, Your suggestion could be right, but the jet kit comes with fatter AND leaner jets, so that it can tuned according to the specific altitude, and or any modifications that haver been done.

 

R34 since i have got a dynojet kit i have had problems myself with fouling plugs and runnin way to rich. I have cut my fuel mix way back and stuck it in all kinds of levels but nothin has seemed to work so its gonna just come out. Also u said it can be tuned...you have to put in a seperate main each time u want to "tune" it to a specific elevation and that is why u get THREE different main jets in each dyno jet kit.

BigBear, Wow.. did you contact those guys at Dynojet and ask them why its burning so rich??

 

R34...no i didnt and im not gonna cause im takin it out this comin sat. Besides a bunch of people i have talked to that i have riden with say that the same thing has happened to them they said they just couldnt get the mixture right with it.So no other quad i buy will ever get a dynojet kit put it tha carb!

 

BigBear, For the what you spent on it, don't you think its worth a phone call ? It might be better than throwing your money away. They might have a simple alternative or method that could solve the problem.

 

BigBear, I just thought about somthing else. When Quads come out of the factory, they are jetted at sea level, and you are at sea level in Texas, so maybe there is'nt a way to improve the fuel mixture any better than the factory could do it whether or not you have a Dynojet kit or any other kit. Where I live, the elevation is 4400 FT above sea level, so it was running richer than it should before I took it out of the showroom. After 60 miles on my new machine, I checked the plug and it was black. So re-jetting can only improve in my particular application.

 

Maybe so R34....im not really an expert on this but the claim dynojet has is that the more fuel the more power and i guess that is what suckered me in.
