need carb or other adjustment?

Mine runs rough and seems to run rich, which could be from normal wear on carb. Are there adjustments to be made? What about compression? What do I need to do to get maximum power and minimum wear on engine? She's going to stay at high altitude.

You should change jets in carburator
there are jets for high altitudes
not expensive but may be hard to find
it will run smoother with appropriate jets.

For compression: if it has good compression
at sea level it will be OK if has poor compression at sea level (under 100 PSI)
you will have to fix it. I saw a compression
chart sea level/different altitudes on this board
may be somebody will remember where it is.

You may check air pressure in tires should be
too high..with care if rear calcium filled.

Good luck

At folowing address you will fin different charts for Ford Tractors there is a compression chart Athmospheric pressure vs altitude vs compression. It is for ford but you can extrapolate for yours.
