A 28PCI Carb is stock for the 36 HP Use Stock Solex #120 or #122.5 main jet ( the original might be 117.5). There is a spring to put into the fuel pump. I guess at high speeds the fuel pump must not have kept upwith the stock spring. This blower is usually stamped VWI and has the double belt pulley. Belt tension is adjusted by the number of gaskets placed between the blower and intake. Front view of a 36 HP Judson Supercharger. Installed on my 56 Karmann Ghia engine. Note the Judson electronic magneto.The Generator Pulley half is a reproduction. 
I never put the belts onto the blower yet. I also have to flare the end of the gas line, any ideas? Front view with the Judson and Magneto, compare the hieght of the Judson air cleaner to the stock air cleaner below. Here I put the stock air cleaner on, the standard Bosch coil, standard fuel line, and standard distributor (I had a Bosch 010 distributor on in the Judson photos, no vacuum advance). On my restored Judson here is what the tag looks like. On it is stamped VWI. Sown here is a 36 HP Judons air cleaner on the left with a 40 HP air cleaner on the right. The 40 hp air cleaner used part of the original VW air cleaner. The original air cleaner snout was cut off and attached to the Judson air cleaner to provide preheat to the carb. Also, the 40 hp unit has a pipe (not shown here) to connect the engine oil breather pipe from the oil filler stand. 36 HP linkage on the left with 40 HP linkage on the right NOS 40 hp Judson belt with Judson Logo on it!!!! The Judson Belt is a "Gates 8210" for 36 and 40 HP. I have not verified this so if someone else knows different please let me know. The old oilers had a Judson red decal placed on them. Shown on the left is the NOS oiler from the 40 HP kit. The original Marvel decal was a water transfer decal where the new ones (on the right) is a paper decal. New oilers are available from Marvel for about $90 USD. Note that the original oiler had a safty wire that ran down under the bottle and the pickup tube was longer with a mesh screen on the bottom of it.
