I recently puchase the above craftmsan, I replaced the battery and cleaned the terminals and dowloaded the owners maual off the internet. I filled it 1/3 ful of fuel and started right up, ran fine in all gears, raised and lowered the deck and enganed the blades and cut fine for about 2000 sg ft of grass, I checked the belts and the tensioners and lubricated everything prior to starting it.

Went out to the garage next day and it was leaking fuel from around the spark plug and had drained all the reaming fuel from the tank. I removed the spark plug and it just drained gas from the cylinder. I let it dry out for 2 days without the spark plug in, I replaced the spark plug with a new one, and put alittle fuel in the tank. It cranks over just fine but wont start, I removed the air filter and noticed when cranking it and even after turning it off is just dumping fuel into the cylinder. I again removed the spark plug and fuel came out for the cylinder.

Any ideas here, thank

Remove, clean and install a carb kit. then change the oil and filter if it has one.

Do you have a fuel pump? Or is the fuel gravity fed? If it's gravity fed, then install a shut off valve. But, you still need to rebuild he carb. Your float is probably stuck open.

Thanks,

I am not sure if it has fuel pump or gravity feed, (Since with the key on it is pumping fuel into the carb and with key off it stops pumping fuel), I'll bet it's got a fuel pump. I'll verify today. I will rebuild the carburetor and replace the fuel line and inline filter. I will also replace the engine oil and the oil filter. and clean the spark plug an check the plug gap.

Thanks

If it's a gravity fed carb, the tank will be under the hood, higher than the carb.
