The K-80 and KA-37 are the last years with the full opening for the carb. The later crankcase have a odd shape with a small hole for the idling intake. It appears it worked fine with the later ones for XR55. So any block from K-80 up would work. Hopefully you can get it going without swapping.


Thanks for the info!
I fired it up this morning using the drill again, seeing how the drill
plate was still bolted on. It seems a little touchy. At least it
required "choke" today before it fired. Of course, I couldn't
run it long enough to do any tuning.
Five minutes later, I put the rope plate back on,
and it did start via rope. It's been quite a few hours
since starting it, so I'll see what happens this evening.
If it does rope start, I'll be tempted to put it on a boat soon!

Great. Also, no gasket between carb and block, forgot to answer that, just be sure to push it all the way in. Maybe it just needed to be woken up. Probably been a long time since that one ran.

It did start up this evening via rope, but it took several pulls
and guess work on the choking. May try starting it every day
for a while to see if it gets any easier, then if it does, throw
in the test barrel. Probably won't cool in the barrel, but at
least I'll see if it will start with the prop thrashing in the water.
