Title: 48 IDF Fuel leak Post by: Ovalboy on May 18, 2008, 21:21:48 pm >:(
Hi guys can anybody out there help me. I'm running 48 IDF's on my Oval and seem to have developed a fuel leak, this is what happens: Start up no problem, run no problem no fuel leak and then when I turn the engine off (and fuel pump) after about 1-2 minutes I get a fuel seapage through the mixture screw and then through the throttle shaft underthe carbs. Today I installed a service kit including the o ring on the outside of the mixture screw, needle valve, fuel inlet filter but I've still got a leak. Just wondered if anybody could help. Cheers Dave Title: Re: 48 IDF Fuel leak Post by: nicolas on May 18, 2008, 21:29:58 pm i had also fuel leaking in the carbs and that would cause a hiss of the hot fuel dripping in the hot manifolds. the O rings were cracked and i cured it with new ones. but i managed to twist one when installing it and the problem stayed with that barrel. so make sure the o-rings don't twist and are good.
and maybe clean the block off balls inside the carb... if the fuelchambers are dirty. |
