<div><br></div><div>But researching down the type 3 rabbit hole, 1965 "1500 S" models and 1966-1967 1600 models (manual and automatics) all use the same distributor, even though they are marked differently. This is because they all have the same exact replacement called out by VW, the "231-137-033". The 231-137-033 needs a 10 degree BTDC at idle, very similar to the "034". So it would work much better at burning fuel when used in a carbureted car than a using a distributor from a fuel injected car.<div>
<br></div><div>I would say the "033" may be a very close cousin to the "034", but with more initial advance. I can't say how close the total combined advance would compare to the "034" because it isn't listed. I would be cautious because I also don't know how much Hg the 32mm PDSIT carbs pull and how much Hg the vacuum can on the "033" needs and how far it advances.<div>
<br></div><div>From what I have gathered, the "best all-around" stoichiometric ratio is reached at idle approximately 7.5 degrees BTDC with most volkswagen dual port engines with stock cams and most Type 4 engines with stock cams. This is general number making the "034" fit nearly any carbureted dual port motor (with some specific carburetor exceptions like a Solex 30/31).</div>
</div><div><br></div><div>I have swapped in many "034" distributors on Type 4 motors equipped with 32/34 Solex's and the results are nothing short of amazing. Also with dual Kadrons on Type 1 motors. It just seems VW worked some real voodoo with the "034" making it a "one size fits all" distributor.</div>

Yes. The 034 would still be the correct dizzy since the<br>
advance curve would<br>
be identical from a manual transmission and standard<br>
transmission using<br>
carburetors. The idle needs to be set approximately 100RPM<br>
higher at idle<br>
to compensate for gear-engaged-at-idle.<br>
<br>
-If I Remember Correctly- VW used different distributors for<br>
standard<br>
transmissions and automatics in two instances. The first,<br>
when fuel<br>
injection was used and the second when emissions were a<br>
concern (California<br>
cars). -If I Remember Correctly-<br>
