OK so I know it's most likely my over torquing of the arc rod bolts, but the engine is in great running condition and as soon as i hit the gas the engine stopped and i went to pull-start it again. After going to pull-start it rotates the rear wheel and crankshaft... I am thinking its because I over-torqued the arc rod bolts and they may have over tightened. I took out the spark-plug and the piston moves freely, however even with the spark-plug hole open when I pull on the pull-start it still moves the back wheels. Just want to make sure its the symptoms of over tightened arc rod bolts. I will remove and assemble them with 170 inch pounds of torque this time. Any point towards the right solution and symptoms are greatly appreciated. :thumbsup:
