Olif..... ..because the N-Tractor carb system is gravity fed, fuel will flow anytime the float operated fuel-valve is open. Inspect it carefully. Your float hingpin could have jumped its locating sockets. Your float could be full of gas and won't float. (tip: submerge your float in glass jar full of HOT WATER and watch for fine trickle of air bubbles) Your fuelvalve pin could be sticking open. Learn to adjust yer carb. Both Ford and Marvel/Schebler say to open BOTH the downpoint mainjet and the sidepointing idlemixture to 1-turn as a starting point. I set my mainjet to 1-1/2 turns and LEAVITT!!! I then adjust the sidepointing idlemixture for maximum idle rpms; not smoothest running, MAX RPM's, understand? The N-Idle is a SLOOOoooww 400 rpms and is set by the behind the carb throttle setscrew. Remember the idlemixture is BASSACKWARDS, out for lean, IN for INRICH. ok? My Idlemixture usually is about 3/8 turn. You replaced yer OLD driedout sparkie wires with soft limp coppercore wires, 1,2,4,3 CCW, didn't you? That means: Sparkie #1 is connected to nipple #1 at 10 o'clock Sparkie #2 is connected to nipple #2 at 8 o'clock simple, eh? now PAY ATTENTION 'cuz it gitts trickey here Sparkie #4 is connected to nipple #3 at 4 o'clock Sparkie #3 is connected to nipple #4 at 2 o'clock therefore firing order is 1,2,4,3...isn't that amazing?
