hey folks... just finished building up my prairie and is running
pretty good... it smokes so i think it is going to need a rebuild
pretty soon... in any case it starts right up on the first time but then
if it is shut off it is really hard to start back up?? it kicks over easy
but doesn't start... i already cleaned the carb but think it could be the
spark plug. any other suggestions... oh and the gear shift is hard to put
in high gear... any help would be appreciated.. thanks..

Generally speaking if there is enough cold compression to start, there will be sufficient compression when warm or hot to also start as long as the valves are properly adjusted.

Warm starting problems are nearly always too tight of valve clearance and the engine leaking compression when the valve stem expands and the valve will no longer close, or it is the ignition coil starting to fail, or a bad spark plug. Any of these problems are a snap to correct.

Oil burning on the 400 is almost always a case of worn valve guides from running with too tight of clearance which overheats the exhaust valves and chews out the valve guides. A wet and dry compression test will tell you if it is rings or the valve guides.

I see a lot of farm used 400's that have thousands and thousands of hours on the engines, and the piston and rings are still like new. But, if the valves are not adjusted correctly they start hard and burn oil after the guides are knocked.

Gear shifting problems are nearly always shift linkage or torque converter related. Check the tolerances and keep them in spec.

Fix the CV slide first. That is your likely culprit right there. If you are sure you don't have a limp mode then the belt check should be done for peace of mind as opposed to fixing the current problem.
