hey guys picked up a makita rst250 trimmer and apart from the shagged flywheel, bent crankshaft and re kiting the carby shes up and running great, but i do have one problem ha ha otherwise i wouldent be here when you swicth it off it leaks fuel out of the carby throat and into the cylinder you can actualy see the little puffs of smoke from each drip slowy rise from the carb throat when turned of hot on its side, wich makes it horible to try and start when its warm even fills the cylinder up enough to almost lock it when left sitting between trips. its a walbro wyc or wyl i think its the barral type with no ajustment needles and has a seperate primer bulb on the return line to the tank so when its primed it pushes a bit of fuel backwards "id say" and that primes it you see it spray into the cylinder if you look down the throat, i have rekited the carb fully and i read somewhere here that they have a purge valve but when i had the carb apart i dont think i saw anything like that just the normal stuff i dont think it could be preshure in the fuel tank either i have checked the cap could it posibly be float needle hight that is one thing i diddent check but ive done about 8 off em now and have never botherd with it and had no probs so far .. any ideas would be very much apreciated thanks guys
