Tuned up a 901 Ford with new plugs, points, rotor, condenser, cap, & wires. Runs OK except for a momentary hesitation when I open the throttle. Owner tells me it wasn"t present before. The carb is a TSX 662 Marvel Schebler. I"m not familiar with this particular carb but would expect this to be normal since there is no accelerator pump. Is it?
The power needle initial setting is 1- 1 1/4 turns but the tractor couldn"t pull itself up a small grade set at 1 1/4 and doesn"t reach max power until it"s about 2 turns. Again is this normal?
Finally, I can"t seem to get a rich idle mixture by turning the idle screw in. My tach/dwell meter fluctuates wildly at both the dwell and RPM settings so I"m not sure what RPM it"s idling at. Is the 400-450 RPM spec critical?
Points set at .025 and timing is on the mark although again I'm not sure of the RPM.
I"d appreciate any help from you Ford experts.
