They are supposed to have the largest collection of Soviet hardware outside of Moscow and the largest collection of US hardware outside of the Smithsonian. I don't know if that is true or ever was. They do have an impressive collection of both.

China has probably sent spies to photograph everything. LOL

That SR-71 is impressive.

For fuel filters look at the auto parts store or even hardware stores where they sell all the lawnmower parts. Get the biggest filter that will fit your line.

The space race fueled our technology and standard of living.

We should have never left the Moon. There should be a large colony there by now with a large spaceflight infrastructure built up.

Intermittent problems are the most challenging.

Did you charge the battery before using it?

Is the large red wire from the battery to the starter solidly connected on both ends? Are the crimped ends good?

Yeah, when the choke is closed it actually decreases the pressure in the venturi so the atmospheric pressure in the float bowls pushes more fuel through the jets. It can't close completely and differential air pressure 'pulls' it open. Carbs are always fun to play with. They are little mechanical marvels. The end result of a real choke or an enricher is a richer mixture entering the combustion chamber.

With this little scoot carb it is going to be interesting to see if I can just cover the air intake snorkle with my fingers to 'choke' it if necessary. I haven't studied out all the passageways and actions in that carb to see if the fuel bowl is vented externally so it sees atmospheric pressure from outside of the airstream. It may be vented by that drain tube. The pressure fluctuations may be enough to enrich the mixture anyway with the spring above the fuel needle.

Peering through passageways and tracking vents is just no fun anymore with my failing eyesight and no short term memory. I can't even carry on a verbal conversation. According to the doctors my brain was 88 years old in 2010, that makes it 92 now. It has not improved with the passing years. Dementia is very real.

That Holley carb does not have atmospheric bowl vents. The bowls vent to the intake airstream through those angle cut brass tubes into the air filter flange. Holley carbs were super tunable and adaptable to varying conditions.
