83 ytm 225dx problem

[tallon]

I just bought a 83 ytm dx and it will start but only runs for a minute before bogging down and smokes a lot. I cleaned the carb and it didn't do anything. I'm thinking top end rings. But it will run wide open before bogging down and dieing.

how old is the gas?

put some gas in a clear glass and look at it . . if it is yellow, it is bad.

you can put an 8" long piece of clear plastic line on the float bowl drain fitting

tape it to the carburetor so the end of the line is near the top of the carb.

turn the gas on at the gas tank.

loosen the screw on the float bowl.

gas will enter the clear line.

the level of the gas should be around 1/8" - 3/16" below the main carb body where it meets the float boewl . . if it is above the bottom if the main body, it is definitely too high and might be flooding it.

..................here's an example of it a little too high . . it should be just below the solid black line in your case.

check your fuel cap, and see if you can blow through the vent hole, if not you are vacuum locking, after that wash out your fuel tank, and pull and clean the petcock valve. Otherwise you are experiencing a flooding issue from the float needle seat o-ring.
