No customers. These are my machines. I am too cheap to buy good running machines. I tend to buy non-runners or running and very beat-up and then fix up for my family.
There fuel pumps are $80 if buy the one made specific for this machine. I already bought a new one from China for $15 and found out it cannot work. It was sold as a "vacuum fuel pump" but looks to be for impulse-hookup only.
I have another Suzuki in my shop that pumps fuel very well. Near the same machine as my non-runner. So I took the pump off of that and put it on this one - and it does not work. So I guess that pretty much proves the fuel-pump is not the issue.
I have NO idea what the theory of operation is. The vacuum source for the pump is a tap on the front of the carburetor by the intake-manifold. So maybe - somehow some part of the carb takes steady vacuum and turns it into a pulse? If so, mine is not doing that since I get a pretty steady 5-6" vacuum reading.
One possibility that is messing with my "cause and effect" diagnosis it this. Maybe the level of gas in the tank was higher last Fall when it ran. If so, maybe the fuel pump never worked and it ran because the tank was fuller. Once the tank is over half-full. gas can gravity feed to the carb. I wish the tank was a little higher and I'd just forget having any fuel pump.
I am usually pretty stubborn and like complex problems. NOT this one. I spend near the entire day on this thing and got nowhere. Unless I wake up tomorrow with a better brain - I think I am going to opt for an electric fuel pump. It is that or mount a gravity-feed tank on the handlebars?
