To pull the bell housing you need to pull the flywheel. And then you've got a "while I'm in there" problem. Sure, they come apart almost easily, putting it all back together is one of the hardest jobs on a LandCruiser.
You can do a heck of a masking job in the time it would take you to stab the...
The first person I would recommend is the owner/driver of the rig. It's not that hard, there are videos of the whole thing and there is much useful knowledge to be gained.
Barring that, Jim C. does know what he's doing.
Some people seem to think that Mark A. can rebuild one as well...
I tried a 4 row core in my 2F powered FJ55 for 10 years or so. Not impressed. The tubes were smaller, thinner walled with thinner fragiler fins.
Went back to a 3 row core a couple years ago. Seems sturdier, more LandCruiserish. Cools just as well, though that's rarely a problem.
That looks like a stock carb, which has a little port hole window that lets you look at the fuel level in the float bowl. Fuel should be halfway up that porthole. Clean yours off and see if you can see the fuel level (probably not).
I just went out and tried to start mine with no choke and no pumps. It's 80*F here now. Engine caught a little on first crank, but died. Tried again with one smooth press of accelerator while cranking and it started nicely but still wanted choke to warm up.
Perhaps we could agree that each...
Pumping (the accelerator peddle I assume) is common but not necessarily normal. What carburetor do you have? Pics of engine please.
A well tuned 2F (like mine) usually takes full choke and 2 pumps to start when temps are above freezing, more pumps when below.
