Only takes a tiny piece of crud in the needle and seat, and it will keep pouring gas in the engine. Start the engine and look down the carb, for dripping gas at idle from the boosters or even vent tube

Dose it have a mechanical fuel pump, with the plastic vent line goins to carb?
Bad fuel pump flooding the carb.?

I'd say needle and seat dumping raw gas too. Had this issue once. It was a build up of that wonderful ethanol gas that I ran.

Make sure you change the oil after you fix the issue.
If your dumping all that fuel down the carburetor you are diluting the oil with fuel and washing down the cylinder walls and bearings etc.

You guys are very helpful. Carb was dumping way to much fuel fouling my plugs and causing the engine to run so terribly. Thanks for the input

Do the carbs have chokes on them? If so, and the chokes/choke is stuck closed will cause a overly rich/flooding condition as well.

Just something easy that noone else said yet.

now see why it was.....like if it was needle and seat like I had once, there was a small peice of fuel line sticking it, replace fuel line to carb..... it will happen again, because if it clogs good you can lean it out and burn it up....

just rebuilt carbs. don't get stuck in the mindset-"i just fixed that. it has to be something else." you could have missed a detail, or a new power valve had a very short life or something like that.

My point was, do the basic stuff first before someone had him chasing down a faulty kill switch or some other nonsense.

You just can't expect this level of quality advice to come out this fast all the time.

I would put a good inline fuel filter before the fuel pump.
