32 pdsit on a 1300

[Voiden]

I have a 1971 1302 with 1300 dual port engine.
The engine is in good condition, but the carburetor is worn out.

I have 2x sets of 32 pdsit, so I thought to install a kit on my engine together with 1:25 rockers and 009 with Ignitor.

How will this be?
I'm not looking for a racing engine, more high MPG engine.
It's my daily driver.

Someone who has done this?

It will be very good, if you jet and tune it correctly.

The twin PDSIT series carbs works well on the late 1300 dual port engine.
I have tried both the 24mm venturies (from the 1600 type3) and the 23mm (from the 1500 type 3) on the 1300. The 23mm has better low rpm performance and uses less fuel. They obviously have to be re-jetted.

If fuel consumption is of any concern to you, DO NOT use the 009. The svda distributor that came with your engine is much better. On mine, i have recurved the centrifugal advance by adding a little weight to the mechanism.
This means that advance is now in at slightly lower rpms, like the 009, and it still has vacuum advance.

What about the linkage???

OK, then I buy a new svda distributor.
My engine has dual vacuum.

What jets should I start with and have as a starting point.
Here in Sweden fuel jets is available in sizes 112,5 to 170.
Idle is available in sizes 45-65.
They cost $ 10 each, and I do not buy too many sizes.

Picture of linkage is not clear, but if it is meant for 2 identical carbs, it may not work for the symmetrical PDSIT carbs. Maybe you can modify the type 3 linkage. If you can find some of the taller aftermarket manifolds it will be better, if not the short type 3 ones should do. PDSIT carbs are very sensitive to the length of piping to the aircleaner. If you plan to use small twin aircleaners directly on top of carbs, then for a start air correction jets will have to come down drastically to compensate. Probably to around 130. If it's still lean at the top end, even try go as low as 110 on your air-correction jet.

If you use the 23mm venturies from the 1500, main jet could be around 112.5 or 115. If 24mm (from 1600 type 3), then 115 to 117.5

Your original dual vacuum advance distributor can he used as well. Just leave the retard side disconnected. You can even use a vacuum advance canister from a different vehicle on your standard distributor. In some countries the early 80's Golf 1800 GTI (called "Rabbit" in the US), had a single vacuum canister which has more advance which comes in earlier. This fits the standard Bosch distributor.

The best distributor to use (my humble opinion) is from the 1900 wasserboxer engine. Use this complete with it's electronic module, wiring harness and ignition coil. Far more reliable than Pertronics conversion types, and much higher spark output than aftermarket types which lacks variable dwell control and are limited to high impedance coils like the blue coil. The wasseboxer distributor (like your original one), can be recurved and a different vacuum canister fitted.

Remember that the 1300 dual port was never sold in the USA, therefore advice may be limited.
