They may be thicker, but what is the quality of the steal?

Check a shop manual for proper valve adjustment. I think valves aren't supposed to be tdc when adjusted. I think there is a compression relief that holds the exhaust valve open a bit.

Did you try NAPA?

Sounds like there may be a collapsing fuel line or something in the gas tank blocking the fuel port, causing it to starve for fuel.

If you have the deck off, engage the pto and see if you can spin the drive pulley. If you can spin it, it's a faulty pto clutch.

Didn't understand what you did with the fuel solenoid. So, I'll just say, remove the solenoid.

I have 2 Hydro-Gear pumps on a Ferris Z 3100. Drove into garage to work on motor and now it won't move. Changed the hydro filter and fluid. The bypass valves are closed. Is there a need to bleed these pumps before they will pump? If so,how is it done? thanks, gregjo1948

Had no luck bleeding air from the system. Didn't help.

I have it jacked up and the wheels do turn in both directions but with no power. I can easily stop the motion with my hand. I'm going to try bleeding air from the system.

the bypasses are both closed.

The pumps are both turning as they should. They are not running the drive motors.

It would need to be a trick belt to get between the pulley and the fans. It is under the pump mounting deck.

The belt is fine. It's easy to see both cooling fans spinning.

working on an older IS3100 That I had to do some engine work on. Engine is repaired and running fine, but the machine won't move. It's been sitting since July 2022. Has the correct fluid in the pump reservoir and the releases are in the right position. It was driven to where it is sitting now...

I'd guess you aren't setting the valve lash correctly. Most small engines have a compression relief built into the cam. It opens the exhaust valve slightly and you may be adjusting the lash wrong.
