    If the crank is only 2" long AND you found a clutch with grub screws, you would have to mount it with the sprocket on the outside. That could cause chain alignment issues. The 2" crank May not be long enough to mount it the other way around.

    Instead of a drilling a hole for the screws, you can also grind a small flat area for them to bite into.
    I may even have a 5/8" clutch with grub screws, I'll look later today.

    Best answer right here^^^.
    Also,
    I doubt that your engine has a "cast cylinder sleeve" as stated by a previous reply. It is most likely a "Koolbore" all-aluminum block, head, and cylinder wall. Are there any numbers on the recoil shroud? If so post them.

    Cutting a keyway isnt that difficult. Give it a try. I think most 5/8" clutches dont have a removable key anyway. It is definately easier on a shaft that doesnt have an engine in the way. I would buy a clutch first then you can see how far you need to go with the keyway. They dont go all the way across so itll save you some work. Keyways dont have to be perfect either. especially if you have a bolt to tighten it down with. Crankshafts also drill and tap very easy so you might consider doing that aswell
