An answer may have come in but I haven"t seen it. Will ask question again. Giving gas to my Super A the tractor will not speed up.
Have check all linkage . While it is in idle the linkage at carb moves back and forth like
governor is working. Linkage carb moves when you push it to speed up. It cranks on first turn of starter . What is my problem?
 
Disconnect the gas line at the carburetor and see if there's a full stream on gas from the tank. Use a clean container to catch the gas. Hal
 
Throttle plate not opening up like it should. Or maybe the linkage is slipping on the throttle shaft. I have seen both happen. Or some other shaft and linkage is slipping so the throttle is not being pushed open. So answer this can you speed it up by grabbing the throttle link with your hand and have it spin up????? Knowing that will help us help you and it does of you try that
 
Take ahold of the linkage rod and work it by hand like old says. If the governor is working like it should,you should feel it fighting against you.
 
then I'd say you have a severe carb problem if the engine does not speed up when you manually open the carb butterfly.

id's guess the butterfly is NOT moving.
 
New filter as in an in line type??? That could well be where you problem is since most in line filters are made to be on system that have a fuel pump and they need 7 plus PSI to push the fuel threw them. I have thrown many in line filters away just because of this type of problem. Gravity flow systems and in line filters do not mix well and cause lack of fuel to carb
 
The throttle link moves the throttle plate when
I move it at the carb. ,but no change in idle speed.
What next? Also when running it runs rich but runs
not flooding out.
 
How do you know if the throttle plate is moving did you take the carb off and have a look see. And if you had a look see did not try to hold the throttle plate in place and move it at the same time. I have seen where the throttle plate will move when carb if off but not when running due to the linkage slipping on the shaft. Why do you say it runs rich?? Black smoke?? What happens if you unhook the air cleaner??
 
There should in fact be ate least one filter in that system if not 2 or 3 but all are screen set ups. 1 should be in the tank at the top of the sediment bowl one in the top of the sediment bowl which is a screen then maybe an elbow one. Had a neighbor that had a B that did the same thing and he had the in line filter. I took it off and threw it in the back of my truck and he never had a problem with fuel again. A few years later he moves and I buy the tractor and it is now in the land down under. Yep sold it to a guy who shipped it all that way
 
something. rebuild or replace.

if you manuall turn the rod the butterfly is on and NO engine speed increase and she doesn't stall. then your carb is crippled badly... and not working in any fashion as designed. IE. the butterfly must not be on the throttle shaft.

this assumes you did the test correctly and correctly reported the results
