even though I squeeze the primer bulb, all
this does is compress air and pushes fuel near the fuel pump.

Nope...When you squeeze the bulb, does it ever get impossible to squeeze
further....Does it squeeze up hard?

The bulb pumps gas through the chinzy pulse rubber diaphram fuel pump into
the float bowls. Once the bowls get full, the point where it's time to
crank, the float valves all close and the bulb is impossible to pump
further...you simply can't squeeze it together further.

If you cannot get it to pump up hard, two possibilities exist. You have a
fuel system leak between the bulb and the carbs...probably a hole in the
aforementioned chinzy fuel pump diaphram caused by a backfire blowing the
diaphram in the pulse-supplying cylinder or old age in the diaphram
itself....or you have a stuck float valve and gas is pouring into the reed
valve body from your pumping flooding that cylinder/cylinders it feeds into
the crankcase.

This latter, of course, is why it's hard to start as it's either flooded
from your pumping or is fuel starved because the pulse pump is sucking air
through its diaphram...or the hole in the hose....never filling the float
bowls in the beast.

If it won't pump up hard, take the screws out of the pulse fuel pump and
inspect the rubber diaphram. If the diaphram looks all wrinkled like that
condom you used to use when you were a teen and had no money for a new one,
replace it, anyways, as it won't pump good and will soon fail.

Of course, if you smell gas pumping the bulb, take the cover off the engine
and look where it's coming from....that tiny hose, buried under all that
other crap, that connects the fuel pump to some other stupidity you can't
identify and will have to disassemble half the engine to change and get the
hose clamps back on straight. It's the only hose that can fail.
