Small Engines (Lawn Mowers, etc.): Bolens riding mower, battery cables, power stroke

Question
I have a 17 hp, 42 in. cut.  Model #13AN683G163, Serial #1LO32B40256.  Purchased in 2003.  Have replaced starter, battery, battery cables, fuel filter, fuel, and cleaned negative battery connection to the frame, cleaned pos. and neg connections at battery and are tight.  Cranked 3 days ago, ran for 2 hours, no missing noted, but not able to crank again since turned off that day.  Flywheel will not turn complete revolutions.  Positive battery cable that connects to starter becomes very warm after repeated starting attempts.  Can you help?

Answer
HI DIANE

CAN YOU LET ME KNOW MODEL - TYPE NUMBER OF ENGINE  

I SUSPECT  BRIGGS OHV  MODEL /

IF SO SOUNDS LIKE YOU MAY HAVE DECOMPRESSION PROBLEM  

TRY RESETTING INLET  VALVE CLEARANCE TO 0.003"  AND EXHAUST TO 0.005'

@ 1/4 INCH PAST TDC  ON POWER STROKE   THIS REMOVES DECOMPRESSOR LIFT FROM VALVE CLEARANCE ADJUSTMENT

MAKE SURE PUSH RODS ARE STRAIGHT ,   BOTTOM VALVE IS INTAKE   AS VIEWD FRONT OF ENGINE WITH BONNET AND ROCKER COVER OFF   AND THE TOP VALVE  IS THE EXHAUST

INLET PUSH ROD ROD IS ALLOY AND EXHUAST  PUSH ROD IS STEEL

ARE YOU SURE YOU HAVE A GOOD GROUND CONNECTION FOR ENGINE  AND CABLE BACK TO BATTERY ?

POOR GROUNDING CAN CAUSE EXCESSIVE  CURRENT DRAW TOO



TRY ADJUSTING VALVES 1ST


LET ME KNOW
