No steam in any cylinders on mine.
..yet.:p

That's good jonesg but keep checking your plugs but especially the #1 and it would look like mud or salt just packed onto the spark plug but I heard only some were bad so you might be one of the lucky ones. Cool and thanks.

Thanks, yes I will try another tester to verify and this was immediately after a decarb with 1 can of engine tuner which I treated one evening, left it overnight to sit then ran it on the hose for 15 mins @ 1,500 rpms then put it in the water and did about 10 wide open throttle runs and it has been 4 days now and no draining from the foot end exhaust port. I hope the 1 can of engine tuner worked or do you think I should do another one?

what kind of decarb ? and how do you do it , i am a newbe at repair stuff. i have 2 engines that have compression that is 10 to 12 % off and it runs kinda choppy

Cityboy, I think you might want to start your own post as this one is a little old. And you'll get better replies.
