Stock Distributor vacuum can questions

I did the same thing with a single vacuum can from Aircooled.net but it wasn't a direct replacement. I had to put an S-bend in the arm to get it to line up when it was mounted and there was a gap at the top. I filled the gap with silicone sealer and the distributor is working fine on my bug.

If I had to do it again, I would have drilled a new pair of mounting holes to give the part the proper orientation. If there's any chance the distributor has problems, a whole new one from Aircooled.net would be the way to go.

Your 30 pic carb delivers a completely different vacuum signal. The 113T dist is the correct one for a 30 carb. It is vacuum ONLY advance. It has no centrifugal advance. Beetle 1970 * 1600 Manual Trans

11-17deg @ 2000 rpm, 21-25deg @ 3600 rpm There is no way a 30 pic carb will put out enough vacuum to give you any vacuum advance. The 30 pic puts out a max of about 3.5 inches.

Years ago, when the vacuum unit died, the dist had zero advance. So some brainchild came out with the 'Screamer Kit'. It contained a 009 dist and the blue coil. The engine screamed because it now had advance!

I do not advocate a 009 whatsoever, but in your case: If the 113T dist is totally not usable then you will either need to use the 009 or shop around for a good used 113T.

The above dist specs come from here:

Someone else mentioned a SVDA dist. But using a 30 pic carb means the SV part will not work. Go to this link and scroll down: You will see that 3.5 inches of HG gives you 1 degree of advance using the Bruck and none using the OEM dist.

The SVDA works on the 34 pic carbs on DP engines. The vacumm signal map is correct for it.
