gasoline !

I'll check on the tightness problem when I can.

Either your mains are too tight or they are worn enough that the helical
gears that drive the sideshaft are binding. Very common problem, can be
properly repaired by jacking up the shaft and repouring the lower mains,
or sometimes you can drop the sideshaft a bit by removing the studs that
fasten the rear bearing to the base and turning the unthreaded portion of
the stud down a little, allowing the bearing to drop down and increase the
clearance between the gears. While not a text book perfect solution, most
engines have enough slop in them to allow you to get away with it. when
all is right, there will be just a little backlash in the helical gearing.
How much do you have now? 
You said that the engine has recast main caps, perhaps the babbitt it a
bit tight in the cap, try shimming it first and then run it a while and
see if the bearing caps get warm.
Those are nice engines, they can run really sweet with a little tinkering.
Get some propane hooked up to it, play with the timing and you should be
able to get it to run so gently that you will never hear it fire.
Christensens are right up there with Foos for engines that are tweakable.
