Checked spark? Spark should jump at least 1/4" in an open air spark tester. What is the compression?

Sorry about my smart a** comment. The guy just joined the group today. Maybe he's struggling to navigate his way to the responses to his post.
Sorry new guy!

Compression, Spark, and Fuel are all needed at the proper time, and the correct quantity for the engine to run.
Does it have a Spark that can jump a 5/16" gap?
Is Fuel getting to the Carb? Is the Float set correctly?
Have you done a Compression Test? If yes, what are Numbers. If No, why Not?

if you have spark, shot of ether in the carb, brrr for a second you can nail it down to fuel not getting to carb then backtrack. fuel filter, gas tank vent valve, etc etc.

It will pop and that's it. Choke wide open after the squirt
imo, dont try to overchoke it, maybe just let it sit, pull plugs, clean and try without choking like i do when i talk to my wife. seems to work most of the time.

If no fuel is getting to the Carb, plugged Lines, plugged pickup in the tank, Fuel Pump defective, or Hoses reversed. Air Leaks in Fuel Line.
Inlet Valve not opening, due to Improper Float Adjustment, or Installation

Does the Primer Bulb firm up?

I've pulled the plugs 50 times hoping to see a wet one. Dry as a popcorn fart

Bulb is hard. Took carb feed off a couple times and squeezed the bulb. Gas everywhere.!!!!

Should the tank be almost the same height as the carb? Like maybe it's too much to pull fuel uphill?

No, tanks are usually a few feet lower than the Carb.

If you have fuel at the carb but not through it it’s time to revisit the carb. IMO
Still doesn’t explain why you’re not at least getting some life when squirting a bit of fuel in the carb.
Did you torque the flywheel when you put it back on? Could have sheared the key if not.

Current update, found the half moon key sheared about a week ago. It's been replaced.
I am getting a couple of grunts when spraying 3 to 4 large squirts. It ran for about 1 to 2 seconds.
