Re: ignition problem
OK, today i tried pumping the bulb why it was running. it still stalled after about five seconds. I disconnected the line from the fuel filter to the carbs, at the filter outlet side. pumped the bulb again and fuel shoots a steady stream out. while the fuel line was still disconnected we put the filter in a bottle to catch the fuel coming out, to see if the pump was pumping, and tried turning over the engine. the engine started and ran, didn't shut off after five seconds. so we connected the lines back up and started it again and it stayed running. Well i guess i couldn't leave things alone at that. i took the top carb's bowl off to see if it had any gummy stuff in it and it was clean, but i had to take it off and put it back on about four time till i could get the bowl to seal. went to start it up again, and it started all over again. it runs for about five seconds then stalls. i tried disconnecting the fuel filter again doing the same thing i did the first time . and still it wont stay running. I noticed when i squeeze the bulb steady stream of fuel comes out and just when the engine starts the pump shoots steady stream then it goes to a fast sputter of fuel all most in tune with the ruff idle. when it was running it would start off with a kinda smooth idle then it would go to a ruff idle is this how a two stroke runs at idle or is there a problem. one more thing how exactly do you test the fuel pump with vacuum gage or the mity vac, cause i have them both.
