If it's idling ok?? Then why adjust the air screws?
Doing the test with starting fluid will insure the air screws are set right.
Setting the screws: turn in till they bottom out(GENTLY) then out 1 and 1/8th turn.
If the motor idles good then ??? Leave it there.
Test: Run the motor at wide open...
750-800 in gear.
Trouble setting idle: start the motor, spray starting fluid around the intake side of the motor. Under the coils/packs and the base of the carbs.
If that makes a difference? then it's sucking air and the gaskets need to be replaced.
The dog just slides back and forth.
The shift rod that goes through the front of the drive can get stuck or sticky because of corrosion and crud build up.
Lube the shift rod and pull up and down all the while turning the prop shaft.
The Force carbs/seats came 2 ways.
#1 came with a solid seat and a needle with a rubber tip.
#2 came with a solid needle and a seat with a rubber o-ring in the seat.
#1 the rubber tip can deform and cause a leak.
#2 certain solvents and additives can swell the rubber and plastics shutting off...
Unhook the shift cables(yes both) then try shifting by hand.
You'll need to spin the prop as you try to shift.
Without spinning the gears and linkage can bind and cause hard shifting.
Pinch off the hose going to the primer after it's started.
Then spray starting fluid around the intake side of the motor, this includes the carb bases and all around the intake side of the motor. If that makes a difference?? Tour sucking air and need a gasket or two.
You add fluid when the T@T is in the down position.
Adding while up, can cause lots of damage.
HOW?? did you add fluid?
Only going up partially? You might need to clean the pump???
Or maybe clean the electric motor??
The hyd. pump: you can not repair the pump.
IF??? you attempt to do anything...
