EX200-2 Manual Pump Conversion Pro/con’s?

Hey guys. Another Ex200-2 here with to many issues with the hydraulics to mention. I bought the machine last year and put two new solenoids, and a new angle sensor in it. Had a deere tech set the pressures and make it right at the time. It ran great for about 10 months and then yesterday it started to stall on me. The pump is stuck at full stroke and won’t let the engine rev past L.

for some reason I can get it to rev up by activating my hydraulic thumb?? Every other function will...
