Finally got my sr running today but it quit after about 5 seconds... tried starting it again but didnt start. After messing with it a while later i tried starting it again an ran for a couple seconds and quit again. I have Fuel and spark...but then it seems like its not geting much fuel, b/c it wants to start but wont... also im not sure if my MAFS is bad or not ill have to get another probably... if anybody might know what is wrong or have any questions to help me figure out what it is please ask or let me know... ThanksI know i posted this in RWD SR also.. sorry but wanted to post it here.
