No I have changed gas and blew out lines.I havent opened carbs however....any way water could become trapped inside and causing this?? thanx for your help.

have you tried cranking it with no plugs in to blow out whats in the cases?

yes several times.........nothing really came out except a bit of oil.

well then if it starts, idles. .. you've checked the reeds, cleared the tank and lines, cleared the motor, geting plenty of spark.... then next id say take those carbs apart, the water may be making the N&S stick..

I went thru carbs and found evidence and tiny bit of water in 1 of them, put them back togethr and it ran perfect on trailer.Got to the water and rite back to same problem.Went home ,thought about it...next day tried it...still fuct....unplugged the 1way vent on the tank and BINGO!!!!!Ran perfect............apparently th line from vent to tank was a bit pinched.....sometimes the simplest things.....Thanx to all who contributed!!
