AnswerHI PHILIP
CHECK YOUR BATTERY 1ST - RECHARGE IT ENGINE SOUNDS LIKE ITS BASICS ARE OK
IE FUEL, AIR, COMPRESSION , TIMMING, SPARK
SET PARK BRAKE ON ,TURN KEY TO RUN MODE
TRY USING CAR JUMP WIRE SET AND JUMP BATTERY AND CONNECT HEAVY RED WIRE TO STARTER MOTOR TERMINAL AND OTHER END OF JUMP WIRE TO POSITIVE BATTERY TERMINAL ON THE JUMP BATTERY , THEN CONNECT HEAVY BLACK WIRE TO A GOOD GROUND ON ENGINE AND OTHER END OF BLACK JUMP WIRE TO JUMP BATTERY NEGATIVE TERMINAL - THE ENGINE SHOULD CRANK OVER WELL AND START
IF ITS CRANKS AND STARTS WELL LIKE THIS THEN HAVE YOUR BATTERY LOAD TESTED
IF COMES UP FAULTY REPLACE BATTERY - BUT MAKE SURE BATTERY NEGATIVE LEAD HAS A GOOD CLEAN SOUND EARTH / GROUND POINT
TRY ADJUSTING INLET AND EXHAUST VALVE CLEARANCE
WATCH INLET VALVE ( THE BOTTOM VALVE) OPEN THEN CLOSE FULLY , THEN ROTATE PISTON TDC COMPRESSION STROKE , THEN CONTINUE ROTATING PISTON DOWN UNTIL PISTON IS 1/4 INCH PAST TDC ON POWER STROKE ITS AT THIS POSITION VALVES ARE ADJUSTED
THEN RESET INLET CLEARANCE TO 0.003" AND EXHAUST CLEARANCE TO 0.005" AND TIGHTEN CENTRE LOC SCREW
NOTE MAKE SURE THAT YOU BATTERY IS FULLY CHARGED AND YOU HAVE A GOOD GROUND CONNECTION FROM ENGINE TO BATTERY NEGATIVE AND YOUR SUPPLY VOLTAGES ARE AT LEAST 12 -12.5 VOLT WITH NO EXCESSIVE VOLT DROP AND THE MACHINE IS CHARGING THE BATTERY WHEN RUNNING
MAKE SURE SOLENOID IS FUNCTIONING PROPERLY AND NO EXCESSIVE RESISTANCE ACROSS ITS HEAVY CONTACTS ( IE BUND CONTACTS )
YOU SHOULD SEE BATTERY VOLTAGE + 1.5 - 2 VOLT ABOVE BATTERY VOLTAGE IF CHARGING SYSTEM IS WORKING OK BASICALLY YOU SHOULD SEE BETWEEN 14 -15 VOLT ACROSS THE BATTERY TERMINALS
WHEN CHECKED WITH A VOLTMETER
CHEERS LET ME KNOW IF THIS HELPS
