I Have a 75 115 V4 with a new fuel tank and line. When I run at half throttle or above the primer ball sucks flat and the engine drops down to idle. I have to pull the throttle back to idle for a minute until it reinflats and then I can go again until it happens again ( every 30 sec. or so)
I have a 75 115 V4 that was running great yesterday. I went to start it today and it won't start. It is getting fuel but no spark I was wondering if there is a fuse in the ign., throttle controls or something I could check.
