Working on a Ford 800, The tractor would not rev up when the lever was pulled back to full throttle, if the lever was worked real slow could get the tractor to rev up some, found that the gas line at the tank was like bubble gum and only had a trickle of fuel, replaced the line from the tank to the inline fuel filter and now have good fuel flow to carb. Found it would still not rev up unless pulled slowly. removed the carb bowl and found that the bowl was clean and passages were clean. installed the bowl and set adjustments on carb, found still had the same problem, tried adjusting the carb and found it was a little better but still not correct, pulled choke and found it did not make any difference while the engine running so for the heck of it pulled throttle back fastly with the choke pulled out and found that the tractor ran great, Thought of hole in intake manifold looked and cannot see one, Not sure if I am heading in the right direction or not, any help would be appreciated.
