Gas leak in Toro CCR 3650 Snowthrower

jlaak5January 16, 2008

Hello all,

I know this is a lawn mower forum, however I was hoping that I could find someone with small engine knowledge.

I have a Toro CCR3650 Snow thrower that is leaking gas. It appears to be leaking right below the choke switch. Does anybody have any idea as to what the problem may be? I would like to fix it myself if possible.

Thanks,

Jim

Likely either a bad fuel line or the float is sticking causing it to flood.

This engine and carb is based on the lawn boy 2 cycle engine. The needle valve and seat is known to leak on those carbs and leak out the air intake. Remove the lower engine cover, remove 4 screws holding carb bowl on, remove float,replace needle and seat that threads in, reinstall float with correct side up, clean inside of float bowl, reinstall float bowl and engine cover. This repair is if the fuel leaks only when the snowblower is not in use. If it also leaks while runnining check fuel lines or even tank fitting.

Eric,

thanks for the info...............now for my next question. Is this a job for an inexperienced mechanic such as myself?? or should I be bringing this to a repair shop?

fuel leaking below the choke switch which he indicated is the oposite side of the snowblower as the fuel tank fitting where the recall was intended for. As far as mechanical ability doing a basic rebuild on the carb is not dificult. if you can replace a cord on a lamp without a short you can do this. Like i said take off the lower shroud to get access or maybe even be able to do it though the acess hole in the shroud. replace needle and seat, make sure float isnt leaking, check bowl gasket and reasemble. Theres no reason to even remove the carb from the engine block. Other trick is if the tank is less then half full tilt the snow blower forward so the weight is on the chute and front end while working on carb and this will stop fuel flow other then the fuel in the line and carb so you dont need to drain the tank. You got nothing to loose since even if somehow you brought the machine to a dealer with a bag full of carb parts they shouldnt charge you more labor then if everything was fully assembled

The fuel fitting leak recall was for the 4 stroke 2 stage Tecumseh powered blowers.The CCR model in question is a two stroke covered by the recall I referenced.The recall had to do with splitting gas tanks but since leaking gas can "run" along parts it is not inconceivable that it could drip from the choke switch.
