This engine on my TroyBilt TB200 mower is suddenly fouling plugs and doubling fuel consumption. Was previously mowing whole lawn in 1/2 tank fuel. Now it uses more than 1 tank to complete the job. RPM'S cycle up and down more now vs. before. Oil level remains fine, possibly slight overfill but has been this level for more than 1 year h
I will check Compression and also Spark (using adjustable gap tester). What should values for each of these be? Also as I disassemble and do visual inspection for "smoking gun" what should I look for? Stuck or partially stuck Intake Valve, etc?
Thanks in advance. Brand new plug after only 1 hour runtime is very black.
