Description:
SPARK PLUG WHEN INDEXED HELPS THIS MOTOR BE MORE EFFICIENT. RESULTS FOUND 9whp/8ftlbs peak numbers with as much as 10-12ftlbs in the midrange. we found the 6 o'clock position on the plug gap to be a great starting point, when the numbers came out, there was no reason at that time to try another clocking of the plug. my hypothesis was that pointed towards the intake valve in the direction the engine spins would show &# power. I did it, it worked then verified it on a series of hot dyno runs. quest
