>>I have a VW 1600 Dual port engine that does not have a mechanical
fuel pump, but is not fuel injectd??? The engine code is AJ 023946,
which I am informed is a 75 vintage or later engine, which should be
injected. The heads are not FI heads though, so I am thinking that
it was coverted to use a carb. Any information that you can give me
would be greatly appreciated. Also, if you can sugest a good engine
book/manual that would be helpful.<<

First off, I would like to apologize for keeping you waiting for
your post to go on the board (I was on vacation and went to San
Francisco. It is very nice there and there are loads of air-cooled
VW's there). Now to your post. AJ engines were produced in late '74
for The '75 model year (so there shouldn't be a provision for a
mechanical fuel pump). It is also possible that the previous owner
replaced the heads when converting to carb (though it would not be
necessary). With F.I. heads, there are provisions for sensors cast
into the head (I would rather machine a F.I. head for bigger valves
so I could keep the sensor provisions or get Type III heads). Some
good books out there, there's of course The Bentley Manual,
also "How To rebuild Your Air-Cooled Volkswagen Engine" by Tom
Wilson, and there's Rick Higgins' "Bug Me Video" series (volume II
deals with engine rebuilds). Hope that helps.
