[QUOTE="Trikky2, post: 127800, member: 240"] On a bay, when theres a reasonable amount of fuel in the tank, the level is higher than the carb. Even more so if the vehicle is parked facing up hill. Hence it is possible for the fuel to enter the engine. Its not siphoning - its simply flowing. Most likely cause is the needle valve in the carb. Either worn, or a bit of dirt jamming it open, or the float not closing it fully because the float is jamming or partially filled with petrol (they can get pinhole leaks in them - just give it a shake and if its got a bit of fuel in it you can tell). Easy enough to fix. :) Once i had one where the owner had re-assembled the carb and left out the washer under the needle valve which caused a similar problem. [/QUOTE]
