Try a new sparkplug first (weakest link in the system) ....could have water in the carb .....start there and we'll go from here ,Jim

If everything checks out, that is it's getting spark and there is fuel in the tank, check one more thing, is the fuel actually getting to the carb. The reason I say this is on mine I'm having a problem drawing fuel out of the tank. The fuel pump is fine but there is an air leak at the fitting at the tank, black hose outside the tank is ok but inside the tank where the clear hose connects the hose has gotten soft and the clamp will not seal well enough to permit the fuel to be drawn out. Last season I epoxyed the joint and finished the season , but I am having the same problem this season. I am open for other ideas. I plan on calling the dealer Monday to see if they have a permanent fix for this. The newwer Models have relocated the tank to allow gravity feed.

I got mine running today. i used a different style hose clamp and left the fitting outside the tank.
