85 LT 125 fuel pump issue
Hey everyone...I seem to be having a fuel pump issue and looking for some recommendations. I recently bought this machine cause it wasn't running right.
Before I start, let me say I know this is a fuel pump issue cause I can use another tank that's gravity fed and the thing runs fine, so I know it's not a jet or float issue.
I can use the prime bulb to get fuel to the carb, but it will only idle. It will bog/kill the motor if I give it gas. I can take compressed air and a rag and prime the system through the gas cap opening and it will run fine for about 10 seconds, then only idle. I know the vacuum line is sucking from the intake and have taken the fuel pump apart, cleaned, and everything appears to be fine. The only thing I am uncertain is a ball bearing and spring unit in the pump. I would think this is some type of check valve.
I'm uncertain if this pump has been taken apart before, so I ordered a clymer manual hoping it has a break down of the pump so I can reassure it was pieced together properly. I'm thinking it looks line cause if the ends were reversed, the fuel lines would be ran a little funky.
Has anyone ran into any related issues like this?
Thanks in advance!
