I didn’t know you washed trucks @Patriotspwashing

No throttle lever?

@Innocentbystander Looks like this

The governor is a little plastic paddle wheel looking thing deep in the bowels of the motor

If you have work and are pressed for time stick a new motor on it for $1,800 and rebuild that one when you get a chance

Yeah that’s the problem. I have fleet work scheduled tomorrow and almost every day next week, with one of those days being the first for a new client. Every shop I’ve called is telling me 2-3 weeks out even though one of the techs I spoke to said it’s a 2-hour repair job. Also both units are mounted to the same trailer so I can’t just drop one off and work with the other.

I also have no idea how to replace an engine or if I can even get it out. Space is tight:

4 bolts holding engine down. Disconnect battery, pull of pulley sheeve, put on new engine, 1.5 hours max. Northern Tool or most any lawn mower shop should have them sitting in the shelf

If you do and have questions just call me. Fuel lines will be the hardest thing. And even that is simple. They are choke happy. Each time it’s shut off it will want the choke pulled to start. But it starts instantly. Make sure shaft size is the same as your current machine.

I’ve called every small engine store and repair shop that’s open in a 2 hour radius and no one has one in stock. Gotta do what I gotta do. Northern Tool doesn’t seem to carry them in store either. They have a gx630 in store in Memphis but all the gx690s have to be ordered.

Can you rent a unit to get you by?

The engine is stuck on the pulley sheave. Anything particular I can do to get it off?

A pully puller from autozone? @Innocentbystander would know that one.

I mean I can’t even get the engine out because it’s stuck. I guess I could loosen the belts all the way and pull the sheave out and then try and pry that off.

Yea I would pull the belts off and pull the motor with the pully attached.

Take the belts off by loosening the pump. Take two bolts of the pulley and run them in evenly on the two inner threaded holes. They will push the pulley off
