G1800 injector pump issue i think

[philkent]

My mower fired up then stopped. No fuel coming out of the injector pump but plenty coming out of the fuel filter.This has happened before and i fiddled around with the stop solenoid but dont think i really did anything and suddenly fuel spurted out of the pump..This time not so lucky..Any thoughts?

Where the stop solenoid pulls the rack lever. If you manually actuate the lever you should feel a springy resistance. If you don't the rack is stuck at fuel cutoff. To fix you must remove and free the stuck components.

Does the stop solenoid move when you turn the key on or off?

No it doesnt but i dont feel like it ever has..ive never really understood how it works but its stopped and started normally for 20 plus years.In fact when you pull the stop lever the solenoid doesnt move.

Plenty of springy resistance I dont feel like the solenoid pulls anything, the lever moves and the solenoid shaft doesnt do anything or so it appears to me

The stop solenoid can be broken, as long as its not retracted.

If i disconect the throttle cable and stop cable and undo the 4 bolts holding it down the rack lever part will slip straight out and i might see something inside?

No it doesnt Update Ive had a look at another g1800 and it has more tension on the rack lever than my problem one does Do you think the injector pump has to come3 out to free up the shutoff?

Pull the speed control plate first to see if that is causing the issue.
there might be a spring attached to one of the levers when you pull it out.

Yup rack is stuck, be sure to note orientation of parts. They can be installed 180’ out. No need to remove throttle lever just pump.
