wet plug!!!

[denhartogsd]

Okay sitting on the bike the back cylinder on the right side keeps fouling out by being wet, checked all the plugs other 3 are dry but black. I seem to have good spark on the cylinder that has the wet plug is it the carb or is it something else? I know I have come to the right place for help! Thanks in advance!:confused2:

Check resistance measuring from plug boot to engine ground. Check plug gap too. It's possible an air jet in that carb is dirty/blocked too.

Checked the things you mentioned seemed to all be ok. Took off both air filters from that side of bike, the cylinder i am having problems with the carb has gas running from where the jet needle seats that is the problem correct? What do I do now. Thanks. Another question with the air filters off I start the bike and rev it shouldnt the slides all work the same? Thanks again!

You may want to ck n see if the needle, w/ the diaphragm, is set the same as the others, that the E clips are on the same notches. On one of my carbs, this winter, the jet nozzle that works with this needle, came loose. It was hitting the back carb cover. I could see the difference in spacing by looking down the throats of the carbs. As I'm a firm believer, dump a 1/4 can of Sea Foam in the tank.
