I just put a new carb on my 8n.i set the idle mixture screw & it idles fine. tried to set the power mixture screw,ran it up to max rpms,backed the screw out ,couldnt feel any loss of power.did have a lot of backfiring though.backfired while running the throttle up. and backing it off.adjusted the scew until i got most of the backfiring out ,put it under load & got the same thing,backfiring n no power. went through the whole procedure 4 times ,same results. I have changed the plugs,wires,points& condensor,rotor&cap.is there a chance that the governor is bad n causing my problem. anby help would be appreciated.

Your govenor may be bad but sounds like you got timming/ignition issues. Your new carb should be easy to tune. Just set the idle at 1 1/2 turns out and the other at 2 turns. That will get you in the ball park. Also, it is really easy and cheap to check/replace the balls in the govenor.

I'm with Zane, most new carbs if thats what you have instead of a rebuild carb are junk. What does it do if you choke it?? Does it stop backfireing?? If so you have either a fuel flow problem or a junk/clogged carb. What happens if you remove the main jet and run the tractor?? Ya I know doing that may not be good but it will tell you a story if it runs with the main jet out. If it runs with the main jet out you have a clogged up carb or a poorly made carb.

No not the governor.

Could still have carburetor problem if there is any water or foreign material still getting into the carburetor.

Another thing is you said you have a "new" carburetor. The only new carburetors that I am aware of are reproductions of a look alike. Not a Marvel Schrebler original. The reproductions have a plastic venturi and are made and assembled by people who work for a bowl of rice a day. That too may be part of the trouble with your carburetor.

In my learned opinion you are much better off to fix the original equipment carburetor.
