This engine is an HO in a 67 convertible. Doesn’t look like many others I have seen, notable oil bath. Thoughts?

H0 is a '67 case. The correct air cleaner has two small heat risers, same size as '66 except '66 had only one. There should be two small holes in the tin to connect the air cleaner heat risers to the small ducts that lurk below.
'67 often had a "one year only" generator with two spade lugs, no ring terminals. And of course your motor has the ubiquitous (and "incorrect") centrifugal advance distributor.
Be that as it may, it's still a '67 motor.

You have a much later carb, what you have is rubber plugs in the ports that would have gone to the thermostat controlled aircleaner warm up valve, and perhaps for distributor vacuum. The stock 67 has a vacuum distributor and smaller carb. The fuel pump is aftermarket. The generator has the remote regulator (under the rear seat?) and is 12 volt
The 67 has a long aircleaner dual snout, with warm up air tube to both sides of the exhaust. The rear tin piece appears to NOT have the two holes needed for the warm up air hoses between the air cleaner and the exhaust.
You may have a 1967 engine case, which would be a 1500cc BUT perhaps the engine upon rebuild has big bore pistons.
You maybe a bit over carbed if that carb is indeed a late carb from a 1600 cc motor, it would be 30 mm venturi for the stock 1967 motor. (30 PICT-1) later ones were 34 mm venturi look on the side of the float bowl for the stamping that gives the size.

It looks like a November 1966 1500cc engine, so a fairly early production 1967 engine. Model year production started August 1st of the prior year to allow time for shipping from Germany to across the United States.

Just about everything on that engine is from years other than 1967 which is very common. Your 34 PICT carburetor a that uh oh 9 distributor do not play well together.

True that, even my 1986 Vanagon has a July of 1985 build date sticker on the B pillar. It turned forty last month. It is a very early build 1986 model. It was originally purchased around New Year 85/86. Built five months before sale.

He means that if you were to get the proper carb with correct jetting for your size of engine and correct distributor to work with the carb, that your driving experience would be so much nicer. Especially while doing around town driving with taking off from a stop.
Tried for years to convince a local fellow to try a vacuum advance distributor. When he finally did, he was like "Holy Bleep" surprised that it made such a difference.

Do you have a bit of a flat spot or hesitation just off idle as you are taking off? That's a common consequence of later carburetors 009 distributor. What carb do you have now?
Correct for a 1967 Bug would be a 1500 single port engine with a 30 PICT carb and a vacuum advance only distributor. The 009 you have on the engine now is very common, an inexpensive replacement that has been available for decades, but was not used by VW on any Bug engine.

Is this because it's cheaper and easier to manufacture the 009 as opposed to vacuum advanced? |

In part, yes. The 009 was a later aftermarket product. You could buy it new and since it was marketed heavily as a “ high performance upgrade” it was a successful sales pitch. So much so, that it was later manufactured in Brazil, Mexico and now China. The correct vacuum advance only distributors have not been available new since the late 1970’s and then only at dealership parts counters with added costs built in.
Pretty much the same story for the fuel pump, coil, and probably the clone PICT 34 carburetor on that engine. Sorry for the bad news.

It is a fifty-seven year old vehicle and parts do wear or START TO LOOK OLD. The other route that could have been taken would have been to replace the parts with NOS or original re-manufactured parts. Going that way requires more research work, time and definitely money. It’s definitely doable but not the easier way to get it done.
Not mine- from the gallery. This hobbiest took the time to research and find correct parts. It cost them more too.

Generally speaking, a centrifical advance distributor (like the 009 is) is set-up so the advance curve is for WOT.
But, at part-throttle, a motor likes more advance and makes more power w/more advance, which comes from the vacuum part of the distributor. |

A strong clue that proves the 009 was never factory installed is that you will never see one with a VW part number. 0 231 178 009 is a Bosch number only. Actually the 009 wasn’t intended for industrial engines either. It was marketed as a cheap replacement distributor for VW engines. The 0 231 178. 003 was the VW industrial engine distributor. It does have a VW part number on it= 126 905 205.
