running either too rich or too lean?

Im assuming its too rich.

Turn your HSN about 1/4 turn clockwise (make it go in). That will decrease the amount of fuel going into the engine. Your carb might be putting a little too much fuel and thats why its bogging out at 3/4 throttle.

Maybe its still running too rich? did you check the glowplug? It could be that.

try going another 1/4 turn closed, if that works, try another 1/8 closed, and keep going from there until your engine hits its prime. Be cafeful not to go too lean though, it can/will damage your engine, thats why its nice to have a temp gun to make sure you aernt too lean.

new problem, same p.o.s runs great,good response, temp never gets higher than 225. when I use the brakes it kills the motor. I know it's closing the carb off but I adjusted all the set screws little at a time. and I need advice...

Had one. Went nuts till I changed the clutch. And your going to need better diff. gears soon. But it's a good ride to learn the ropes with. Check the OFNA forums for the other stuff you might need.

If your low speed needle is at flush then you need to go in a 1/4 lean, it's loading up too much if you keep turning in the idle screw, but it should not go more than a 1/2 a turn in from flush.
