Help with new distributor for stock 6-volt 1966 Beetle

[Pruneman99]

Your distributor should be set at idle, with the vacuum advance disconnected and plugged at the carb side.

SVA distributors use vacuum to advance the carb. The signal will not be correct to check max advance without load.

Wait a minute... You have a 111 905 205 M distributor? Are you sure that isn't a 113 905 205 M distributor? The first one (111 905 205 M) is a late 40 horse distributor designed to be used with a 28 PICT-1 carburetor. The second one (113 905 205 M) is a 1968 distributor for a 1500cc single port and would be a better match to a 30 PICT-1 carburetor. Timing advance may be quite delayed if you are using a 40 horse distributor with a later carburetor. That would negatively impact performance.

Stock for 1966 and 1967 Bugs would be the 113-905-205K distributor with a 30 PICT-1 carburetor. The details of the carb are slightly different between the 1300 ('66) and 1500 ('67). If yours has been bored out to a 1600 I would likely try to set up the carburetor and distributor to the 1967 specs, except 6 volt. Timing should be set at idle with the vacuum line disconnected and plugged. What it should be set to will be determined by what distributor you are using.

The only difference is the K uses 2 piece points and the M uses 1 piece. Otherwise they are basically the same.
