My dad gave my son his old XL250 that has been sitting in a garage/barn close to salt water for the last 20 years...with the head off.....:icon_mad:My boy is stoked to get it & see if the ol girl still can run. Got her all back together and she won't start. We filed and re-gapped the points (have spark), we cleaned out the carb, but two things seem off. When I kick her over, I get positive pressure out the carb and when we turn the gas on, no fuel is getting the the carb. Tried a squirt of starting fluid, nothing. Fuel shut off works (pulled the fuel line off and gas flows). I'm thinking that when the head was off, the timing chain dropped off the lower sprocket and were all jacked up with timing issues. I figure that's why the positive pressure in the carb (am I thinking correct)? Not to sure why the fuel isn't filling up the float bowl. Any help would be super cool. He's pretty bummed this bike isn't on the road yet.
