John Deere 12 & 14 Series Common Problems This Manual Covers
John Deere 12SB two-cycle engine cranks but will not start or starts hard after winter storage
Check spark plug condition and gap first, then work through the troubleshooting chart starting on page 438: cylinder compression, muffler, crankcase seals, carburetor, and air filter. If the flywheel was pulled during ignition service, verify the flywheel key is intact and torque the flywheel nut to 41 N·m before retesting for spark.
Manual Section: Engine Operation Tests and Adjustments - Briggs & Stratton 2-Cycle p. 438Four-cycle engine runs rough, misses at full throttle, will not stay running when warm
Check the diagnosis procedures for the four-cycle Briggs engine beginning on page 455. Drain stale fuel, clean or replace the air filter, and inspect the carburetor. On 14PZ and 14SZ engines, measure valve clearance cold and set intake to 0.12-0.18 mm and exhaust to 0.18-0.23 mm per the specs on page 421.
Manual Section: Engine Operation Tests and Adjustments - Briggs & Stratton 4-Cycle p. 455Blue smoke at startup and oil soaking the air filter after tipping mower on its side
Drain the crankcase through the cover drain plug and reinstall it torqued to 21 N·m on Kawasaki engines (page 29). Refill with fresh oil; 14PB, 14PT, and 14SB crankcases hold 0.60 L (page 20). Clean oil out of the air cleaner housing and replace a soaked filter element before restarting.
Manual Section: Engine Operation Tests and Adjustments - Kawasaki p. 495Self-propelled drive slips under load, wheels barely pull in tall grass or uphill
Inspect the drive belt for glazing, cracks, and correct routing, then verify shift cable adjustment using the power train diagnosis procedures beginning on page 631. If the transaxle gets opened during repair, repack it with 70 g of grease on 12SB, 14SB, 14SC, 14SX, and 14SE units (page 20) before reassembly.
Manual Section: Power Train Operation Tests and Adjustments p. 631Blade brake clutch slips or blade keeps spinning after operator releases the bail
