So after about 50+ hours of working on my shop project, my L2850 GST suddenly is extremely hard to start. It had been running great and always started with ease up to this point. I pulled the fuel line off the lift pump, and it seems to be pumping ok, not a lot of volume or pressure, but it is pumping. So is my main pump shot? How do I check the main pump? Is there a rebuild kit out there for the main pump?

I figured it out. The guy I hired to move some dirt around had shut it off with the fuel cutoff lever. I cycled the lever at the pump several times and now she starts fine. Must have been stuck partially open. Starts great again. Guess I need to pull the shutoff cover, and clean and lube the lever.

Gotta like an easy fix!
My old L2850 only has manual cutoff for shutting down. I should go through my cutoff-I’ve been plagued with it not restarting hot, but haven’t found anything amiss in the fuel delivery, but am now wondering if it could be the cutoff.
