Hello, I'm a newbie to the group and the n series tractors and have a unique issue. Also, I apologize for the long post.
While bush hogging in low range 2nd gear 3/4 throttle my 9n will plug along just fine and never miss a bit when I'm going thru heavy grass or uphill causing a load on the engine and the governor will add fuel and hold it if need be to if it starts to bog down. When I'm free wheeling going down grade or short grass it will act like it's starving for fuel at times slightly missing. I've checked fuel flow, cleaned fuel tank, cleaned sediment bowl and screen, cleaned carb and adjusted it lean/rich/just right, made sure I've got good spark, set plugs to proper gap, replaced intake gaskets, checked compression, made sure all my lifters and valves are set and working correctly and done everything I can think of. Anyone else ever had this issue? One thing I have noticed is I can see it blowing compression around plugs by spraying a little wd 40 around them before starting it up. I'm afraid to over tighten but they are definitely snug.
-1941 9n Ford Tractor Sherman Step Up
-MID 90's PSI Compression all cylinders
-Holds Great Oil Pressure
-12 Volt Conversion with Dragon Fire Electronic Ignition,Dragon Fire Plug Wires and Dragon Fire Coil. Autolite 437's and tried Autolite 216's
- New Zenith Carburetor (I also have a new TSX 33 in box does same thing)
-Replaced Starter Switch, Resistor Assembly, Ignition Switch, New Battery, New Wiring Harness to everything
-Added the spin on oil filter adapter
- New Governor (Off Ebay though for around $250)
- Vertical Exhaust no muffler[/u]
