Started it up again tonight. There is no vacuum, which is likely why the brakes were not working. Seems to run really well. A bit of a bog off idle probably timing but I am not seeing a regular timing indicator marks on the crank pulley (not sure there is even a balancer on this engine?). The air cleaner hooks into the brake booster vacuum line (it look like a 3/4 or 1" hose running to it!). Not sure how exactly to seal up the air cleaner to get vacuum to build. I think the vacuum canister is next to the carb but not sure really, and it doesn't appear to be connected to the "manifold" the brake booster unit is connected to. I think If I can get the vacuum issue sorted the brakes may actually work!
Dump seems to work pretty well. There are 3 cylinders, one that does most of the work to get the box up the first couple feet, then two others that lift it faster take over.
