So about 6 months ago i bought a 1978 dt175 and fixed it up a bit and has been running pretty good. I go to take it for a ride the other day and its running terrible for about ten minutes then dies and wouldnt start again. the only way it would stay running for a bit was with the choke in. I took apart the carb it seemed fine, checked fuel line, it was gettin fuel, checked spark and bought a new plug, fine, and still wont run. i kicked it probably 100 times with no start up and a weird sounding fart noiseoutta the exhaust about every ten kicks. What do i do?
also it appears to have some soft of fluid wetness where the head meets the block. could this have something to do with it? thanks
