Hey fellas, Brian again. Neighbor heard I been wrenchin on my X350 and asked if I'd look at his Troy Bilt Pony before winter. 17.5 Intek, bout 10 years old n 300 hrs.
Ran through everything you guys walked me through on my own stuff. Fresh battery, cleaned grounds, starter bench tests fine, strong blue spark, fresh gas, carb clean, valve lash set. Fires on starting fluid for half a sec then dies.
Heres the weird part. Plug out it spins beautiful. Plug in n the starter grunts, slows way down right before TDC on compression, sometimes kicks back hard enough you hear the bendix clack.
From what I been readin this screams sheared ACR tab on the cam. Pulled the valve cover n dont see the little pushrod bump before TDC either.
Am I readin this right before I crack it open? Whats the compression number im lookin for to confirm? TIA
