The points pin where the spring sits on is short and shouldn't be tall enough to touch the cover. The points spring needs to be in contact with the pin as that's the transfer of the connection to the pin and the condenser. Make sure that connection is clean. Clean the post and the spring. 
 
A cause of running erratic is typically the case seals. Leaking seals will affect the vacuum/pressure pulse pressure of the carb diaphragm and that's how the diaphragm moves to pump fuel. When fuel is pumped erratically it will run erratically and no adjustment to the carb is going to fix that.
 
Clean ALL the points connections
Add a few drops of DOT3 brake fluid (Not synthetic ) to each of the crankshaft seals with them still in place on the engine. Let it sit at least over night. Brake fluid swells the rubber and most times will be enough to seal the crank. There are other  little O ring seals at the points push rod and the one screw for the carb. If they are missing it will cause a big leak
Bent or damaged carb to case gaskets can do the same thing

Didn't have time to really set up the display so they ended up scattered on the trailer. There was still a couple left in the van.
 

SUCCESS...!!
 
Another TT300 comes back to life. Wallfish, without you this would have been just another one of those non-running display models. I cannot thank you enough...

Next Saturday is a smaller get together up in Maine so figured I'd bring up some of the stuff that doesn't go to the big shows. They haven't seen the light of day in a LONG time so it'll be nice for people to see them. They're too small and expensive to leave unattended at the big shows although I have never heard of any stealing of anything at any of them.
Just a small sample and will probably bring about 20-25 tools or so depending on available time to get them out. Pictures of the entire display all together next week

 
NOS PC3 Fogger
LA Fire Dept's Fan
Bridge's Drill from UK
Grass trimmer from UK
Petro Drill
Lapadary saw
NOS green Amp Champ
Orline Cut Off saw

This WAS a nice NOS chicken power unit in the original box too
It's been packed way in the back and has been there for a very long time. 2012 maybe?  Pulled it out today and discovered the ruined unit. Mice made a home in the box and the urine covered thing now needs a complete overhaul and paint.

I know just the hardware store to go visit. Thanks again...!!

There were 2 different sizes but I "believe" yours would be the smaller of the 2 . They are 1/16 and 3/32 ball bearings. They can be found at old school type hardware stores with all the little parts in the drawers.

The little steel ball bearing in the carb is not sealing. You can see the bearing in the carb pic above. That ball bearing sitting in the hole is the check valve. If fuel is pushing back past the ball, you can see it travel towards the tank. If the ball is sealing well, the fuel will travel through the carb to the engine.
Getting that ball to seal better will help with performance of the engine.

I thought we had see this one before, found the other post…

Nice find! You are carb heavy now
I'd be interested in these!
Well, actually I'd be interested in all of it but let me know if you're willing to part with those boots and cable. I don't know what the black boots were used for as an O&R application but I have a tractor project that needs boots for 3/4" rod

Here is what I got this weekend at a show. All NOS parts. Still not sure what some of them are for. A friend got them at a show for me and I picked them up this week.
 
 

Post some pics right here so we know exactly what you have and need

I have seals but no way to ACCURATELY measure them, other than a ruler. Webhead should be able to hook you up with new seals and gaskets.
 
You shouldn't need a puller to remove the clutch. Should be a bolt or screw which holds the center clutch part to the shaft. Some shafts are D shaped, some are tapered shaft. You'll need to look down inside the center, under the clutch springs. Think the blowers used the bolt with a 5/16 head. I can open one up and get pics if needed. The clutch pictured from the winch is an old style cork lined clutch, I believe yours should be steel with 2 flat springs spanning the center hole. Pretty sure this is a drawing of your gearbox.

Sorry about that!! Click on the link above (I fixed it!) and scroll down to you see the rod bearings. And yes, there should be a cage. I'll see what I can find for parts

Found some photos on eBay.  Looks like maybe a one-off version of the Aquabug made by Italian scooter/moped and bicycle company, Doniselli.

Thanks for the info , I was told it was for building log cabins but I don’t know anything about that … Time to disassemble it an run it through the vapor blaster an get it ready to restore ,,

That's a JB Power chipper saw. I have one but have no idea what it was actually designed for. It does cut nice 3/4 wide dado joint slots.
Mine didn't have that little bar guide on the bottom so that adds to the mystery. Pretty rare O&R tool as I thought I had the only one! LoL Just haven't seen another until now, even on the web
 

Checked out that old video and I think I can out run you now. We need to have a go of this again

Found some smaller lights and put on the dual light set up. Looks more "factory" with them
