Tex..... .you've got WEAK ELECTRICS caused by ....are you ready for this?.... RUSTY sheetmetal joints in the battery tray. Get rid of that 5"-flatbraid positive ground strap and replace it with an 11"-long flatbraid ground strap bolted to one of your CASTIRON steering gearbox attach bolts. Understand? (this will also improve yer weak sparkies too) Then unbolt yer 8"-long starter motor bolts and slide yer starter out about 1/4", now WIRE-BRUSH the starter endplate GAP. Now yer 6-volt starter will just ZING. Understand, the 3-terminal starter solenoid little middle terminal is GROUNDED by the BIG thumb button by the tranny shifter. Sometimes, it doesn't always make a good ground when you push on it, but that is the least of your worries. (tip: you can also use a screwdriver to ground that 1-ground wire at either end for starting) MAKE CERTAIN YOUR TRANNY IS IN NEUTRAL!!! And surprizingly enuff, with old non-running 6-volt engines, a 12-volt JUMPER DIRECT to the starter motor STUD (flat copper strap) doesn't hurt the starter motor and really spins the engine for better "first-starts". Starter motor don't care 12-volt battery polarity. Many times, OLD non-running engines need rings re-sealed for MORE COMPRESSION. Squirt about 1-oz regular engine oil (or automatic tranny fluid) to re-seal the oilrings. Crank yer engine a couple of times NO SPARKPLUGS to redistribute the oil. Now NEW AutoLite AL-437 sparkies, gapped 0.025". tip: ALWAYS have a spare dry clean set of sparkies to REPLACE anytime you have starting troubles 'cuz you've FLOODED yer engine with INVISABLE no-lead gasoline. no argue, replace. After you get your tractor running, you can replace 1-sparkie at a time, and let the HOT ENGINE clean and dry the contaminated flooded sparkie. You need to gently stretch yer squarecan ignition coil danglin' springy-thingy for more certain contact with the hollow-head condenser attach screw. You need to make a CALIBRATED sparkie tester by taking any old sparkie and bending the side electrode out for FULL 3/16" gap. Clamp the tester metal shell to enny convenient ground and plug enny sparkie wire to top of tester. Now ignition ON, crank yer starter motor and watch yer calibrated tester. Do the sparkies jump the gap with "blue-snott" authority? or are they a yellowish-orangish wimpy excuse? (n.b....my eazy starting 6-volt 8N sparkies will jump a full 3/8" gap) Iff'n you been muckin' with them handy-dandy carb tweek'ems, DON'T!!! Iff'n ya did, bad boy (grin) Try resetting the side-pointing idlemix to 3/8-turn and the down-pointing mainjet to 1-1/2 turn to gittcha started. Final adjustment is MAXIMUM idle-rpms, not smoothest idle. Iff'n you need more carb tips, ask..... ...HTH, Dell
