JB Weld is an epoxy and works really well. You could just leave the spike off if you are concerned about it not holding. If you end up using the P61 crank, use the main bearings that came with it as the 655 had a bearing change. You could see about getting a piston and cylinder kit for the 655, but if you don't have the ignition and flywheel it gets to be an expensive exercise. If you are looking for used parts, the 655 uses its own flywheel, # 476524. The only donor saw using that flywheel is the P65. The ignition module used by the 655 is #476339. It is a common module used by the following saws. P39 and P39+, P42, P45, P52, P52+, P62, Poulan Pro 405,455,525. Watch out for the early P39's as they used a blue coil, the same as the farmsaw series, and it will not work plus they seemed to have a high failure rate.
