That 3 wheeled BMW engined thing
Original pump failed, my x boss got a new one and got it running, rough though. Called me in to see what I could do and the new pump wouldn't go. He sent it back and got another and away it went again. I go out there a few days later and the new pump has stopped working. I bring it home and get it going after slapping it around and refit although the pump sounds rough it fires up.
Went and stuck some new plugs in this afternoon and sure enough the pump won't work again.
Gonna suck some fuel as a sample to be sure but I suspect chinesium shit.
