I do have two vacuums exactly as you describe. Power brakes work fine.
I connected my vacuum gauge to the rear carb, and the vacuum gauge never moved when I opened the throttle.
I used my existing vacuum hose (which doesn’t leak when I blow into it and hold my finger on the other end, I will replace that hose this afternoon and make sure the hose is ok.
The car is a “standard” 300H with 2x4 carbs on a manifold ex factory. (No rams).
Yes, my vacuum line comes from the rear carb.

Remember there are two "vacuum" take offs on the cab(usually). One is metered and the other is direct. meaning One only sees vacuum when the throttle opens; the other has vacuum constantly. I can't say why you don't have any vacuum, but something is not correct. Check the manual to see just what the 300 distributor requires. Does your 300H have the in line 2x4 setup or a Ram? On the inline the distributor vacuum comes from the rear carb, assuming your running progressive linkage; the Ram probably "T'd" to each carb, then to the distributor. Sorry I can't help more. Good Luck.

I have been intermittently working on my 300H the last few years in my spare time to make it roadworthy. I keep coming back to the crummy engine performance. Past test drives have diverted me to doing a 100% brake job, front torsion bar rebuild and steering box rebuild.
The car just doesn;t have as much power as I would expect, even considering the awful gasoline. I finally recalled the car sometimes ran prety poorly when the vacuum line to the distributor was left disconnected. I checked that this morning, even disconnected it while it was running. The vacuum hose is clear, but when I connect my vacuum guage to the line I find no vacuum, Zero at any engine speed.
Do any of our experts have any suggestions before I start digging in?
Thanks, MIke Moore
