Won’t start

Are you , at least a capfulscared to crank it?
If you have already splashed gas down the primaries several times, then you may have washed the gas off the rings.Time to start over.
If you suspect this; pull the plugs and squirt some oil in there, don't be shy a couple of teaspoonfuls won't hurt it.
Then screw the 3/4" reach plugs in about half way and crank the engine over several revolutions to distribute the oil, then pull the plugs, clean up the mess and wash the plugs.
Let it sit for a half hour or so, while the plugs are drying, then re-install them.Then
make sure your fuel line is fully installed all clamps are tight and nothing is leaking. Then
like said; splash some gas down the primaries, if it was me it would be a couple of capfulls,lol; then,
floor it! and crank it! 20,30,40 seconds on round 1,keep it floored, if it takes that long .Unless you have a fuel leak; keep cranking and keep it floored and cranking until it actually runs on it's own, You will not hurt the starter; it has an overrunning clutch that can take this no problem.Once the rpms start to climb past say 1200/1500 let off on the starter, and buzz it up to 2000 for say 10/15 seconds...... Then see if it will idle. By now the pump has filled the bowls, and the float level is stabilized. and unless you screwed up, on the rebuild, everything should be peachy, and she's idling again.

With 2 capfulls down the primary, you have to keep it floored, else you WILL BE FLOODED AGAIN.
You HAVE TO KEEP CRANKING, because it is the heat of compression that is gonna make it possible to ignite that stinking rich mixture. and
You HAVE to KEEP CRANKING, to blow all that oil outta there which is just gonna get in the way of the fireballs. But you gotta have that oil in there to seal the rings to make the pressure, to build the heat so you got at least some of that gas willing to burn. So keep on cranking, until it hits on 4 or 5 or 6 cylinders, and the rpm is scooting up past 1500, cuz if you stop, crapp!
