When you say you block the hose from the filler cap, did you also block the manifold nipple?
Maybe a couple of pics of your setup might help.

It ran horrible for a number of reasons when I got it. The engine and trans mounts were completely gone, the break booster was whistling and sucking in air. The carb throttle shaft was worn flopping around and a carb and dripping petrol from the cold start. I used a B1CC (for 3573 carb) needle from Burlen and their rebuild kit. I fixed the cold start (choke) leak by polishing the disk surfaces and putting a small ‘o’-ring on the inside of the shaft as there was nothing in the rebuild kit for it.
By blocking the hose, I mean pulling it off the fill cap and plugging the end with my finger. There are no vac leaks on the hose or at the manifold nipple.
A smaller orifice in the breather nipple on the manifold might help, looks to be about 3mm or 4mm... maybe make a little disk with a 2mm hole and place is inside.
