1300cc single port carb and dizzy combo??

[bw65vw]

My son bought a 72 super beetle and it has a 1300cc single port engine from a 66 in it. The engine has been rebuilt but has some hesitation with acceleration. The PO also had a Solex 34 PICT 3 carb paired up with a 009 dizzy. I have read on here that this combo is known to have that problem. So I'm wondering what would be better to replace the carb, dizzy or both for better and smoother performance? I have read here the Solex 34 need a vacuum advance dizzy but is this carb too big for the engine? I have an old ZV/PAU4R5 dizzy in a parts box that probably needs reworked but I understand they are vacuum advance only. Any suggestions are appreciated. Thanks!

I doubt this engine is a 1300 single port engine any more, because a 34PICT-3 will not bolt onto a 1300 single port intake manifold. What kind of intake manifold do you have here??

Here is a pic of it

You need to ash can the 009 and find the stock VW distributor that matches that cab. Make sure the heat riser on the intake is not plugged with carbon and you have proper connections on whatever exhaust is on that engine too.

Your throttle hookup looks pretty flakey too by the way. I hope the engine bay has all the right tins and seals in place ...

Show us a photo of the intake manifold. The numbers on the side of the carb. Without that information most of us are not able to give you good advice.

These are the only other 2 pics I have I can ask him to take some more. I told him that fuel line/filter situation going on there has to be fixed too.

I have come across such a manifold once or twice. I believe it is either from a 1600 sgl port industrial engine for the US market, - or from a 1 year production KG 1600 sgl port. Someone might be able to shed more light on that.
However, if the engine is really only 1300 displacement that is not the carb to use. Too "big" due to too large idle bypass etc etc. It can be made to work, but it is NOT for the average tuner.
I would take a volume measurement and figure out what the displacement really is and then work from that.

Sorry I should have given more information. We had the top end of the engine apart due to a bad cylinder head when he first got it and had a local builder rebuild the bottom end. So we do know it is a 1300. He just recently got it back in the car to try it out. Those where the carb and dizzy on it when he got the car. So we are trying to tune the engine and get it road worthy now.

It would be highly unusual for that engine to have been built back up as a 1300. Check with the builder that it's not a 1966 case built up as a 1600.

If it's truly a 1300 I would run the stock carburetor, a 30 PICT 1 Solex with the matching 113 905 205 K distributor to get the best performance. Even if it's a 1600 you could run the above pairing as long as you are not looking to race around town

Some numbers I'm interested in knowing here.

The full part number of the intake manifold.

The Modification State Number of this carburetor. It should be on the base flange of the carb on the left side. (ie... VW 377_1) The carb in the photos has way too many vacuum fittings on it.

After struggling to get my 1600 SP to run right with a 34PICT-3 and a 003 distributor I gave up on them and went with a years matching 30PICT-2 and a 205T distributor. The difference was amazing, the engine has never run this good! One tap on the gas to set the choke and it starts with no baby sitting and runs all day long with no misfire, stumble or hesitation ever.

Could I gain a HP or two with the 34PICT? Maybe but I will never miss it on a 1000lb Buggy riding the trails in the hills. You might in the heavier Super Beetle on the freeway.

Agree with all of the above except that numbers matching with a 30 PICT 2 carburetor would have been a 113 905 205 M distributor. The only real difference being that the 113 M uses the short cap and rotor as do the earlier distributors. The 113 M and T even use the same vacuum canister on a vacuum advance only distributor so it's a small correction.
