Guys I collect orange tractors. Not use to the red ones. I"m working on one for my dad. It runs great, but I can"t seem to get the rpms up high enough at full throttle. It looks like the governor Is adjustable. Is it? How can I increase the rpms. At full throttle it is just alittle above an idle.

sounds like you may have a stuck govener.
If you move be hand the linkage that goes to the carb. can you rev it up? oldiron29

After you check the linkage by hand as oldiron says, check the governor spring. If its weak or sprung, it will not allow for high RPMs.
