Re: Big Twin 40 With No Spark
What he said. Also, when you put the puller on and tighten it to pull the flywheel, it may not come off immediately. You'll also need something to hold the flywheel while you tighten the puller's center bolt, and when retorquing it. You can make a flywheel holder from a piece of 1/4" thick flat bar, drilled to match two of the recoil mounting holes. It's the easiest thing.
If the flywheel doesn't pop off, even after really tightening down the puller bolt, go away overnight, leaving the tension on the puller. Most often, even a really recalcitrant flywheel will pop off with some time. Don't beat the crap out of the flywheel or puller bolt with a hammer. That trick can damage the flywheel or crankshaft bearings.
Finally, when you put the thing back together use a brand new key. Don't even think about using the old one to save the dollar a new one costs. And yes, an accurate torquing is absolutely essential.
