Well, my “banjo” bolt seem to work great, but I did have a slow drip.
A worse problem was gas bubbling out around the poppet valve cover.
Looking back in my records, I see that I ended up installing different pistons,
rods, new rings, etc., as the original pistons had a lot of pin slop.
It might take a while to get the new rings to set in, but the compression seems
good.
It wouldn’t stay running in the video so I put the camera away.
Came back to it a few minutes later, started on the first pull,
and stayed running, but it quit pumping water after a couple
of minutes so I shut it down. 🙁
It stayed running with the carb needle about 1/8th turn open.
Took the motor back to the workbench and took the carb back off
to address the fuel leaks. The Poppet valve “Stop” (cork) was a good
5/16″ above the valve stem when closed. It seem like way too big
a gap, so I made a new stop out of Derlin rod, and the gap is now
1/8″. Any idea if there’s a general rule as far as “gap” on these poppet valve
carbs? Does the gap even matter as long as the valve can open a little way?
I didn’t see much of anything for sea weed plugging the pump screens,
and while my test barrel is pretty murky, there shouldn’t be much sea weed!
I blew into the tell-tale outlet with my air hose, and there didn’t seem to be
any obstruction. Not sure if the metal impeller sheared a pin, or if it’s just
time to clean the test barrel.
I didn’t get to re-try the motor afterward, as it decided to rain the rest of the afternoon.
