Have you got the mag timed to the camshaft gear.
Remove the pipe plug from the back side of the mag and align the "M" stamped on the magneto gear and the camshaft gear.
60psi is good compression....they seem to function even as low as 40psi.
When you get it going if the carb responds to adjustments and you don't have to run with choke applied you accomplished that task.

I rebuilt a carburetor for my D2 pony and had the same problem. It's a little tricky adjusting the mixture screws because of the linkage for the main needle. You can't tell if it's seated, and you screw it IN to adjust the mixture rich, OUT to lean. It takes some time, but you'll get it eventually.👍
Rich, I think you might be on to something. I've taken both the Idle and the main needle adjustments in all the way and then backed them out 1 turn thinking that they would be lean in. I'll have to take the main needle out tomorrow several turns and see if that helps.
Thanks for the tip.

Larry---the main jet adjustment is different depending if you have a horizontal or vertical screw adjustment. horizontal in richins the mixture and verical out richins the mixture
Even if the Carb adjustment is off, it should hit a time or two. How about if you shoot a bit of ether? or give it a drip of gas down the pipe?

Be careful with using ether on the pony motor to start it. You're better off not to use ether on the pony motor at all. Instead, use gasoline or maybe a squirt of WD 40 in the pony to start it. I once blew up my pony motor on my D8 14A by using ether. It didn't get past TDC when it fired and when it kicked back, everything got twisted up inside. The carnage wasn't pretty.That was an expensive lesson for me. It cost me over $3,500 for NC Machinery to rebuild it. Not finding all of the needed replacement parts was the biggest problem for the huge expense. Even my pony's electric starter motor bendix was destroyed in the kick back.
This is what I love about this website. The information never stops flowing. I have the horizontal adjustment and only have about a turn out on it. Based on the information, I'm giving it way too much gas. I so excited to see if this is the problem that I'm headed out there in the rain right now.
Thanks,
