| I'm building a 1600 dual port with a stock crank , scat c 25 cam , stock heads , 85.5 pistons planning on running a pertronix stock look electronic distributor with vac advance and dune buggy exhaust . I'm looking for advice on witch carb to run . I would like it to idle and run smooth. Its in a short fiberglass dune buggy , so I don't think power will be an issue however it will be driven in a lot of parades in Florida heat. Don't want it to run hot |

| Stock carb for a 1600 dual port would be the 34PICT-3 and probably the simplest choice. They run best with a SVDA distributor. Get an original German carb if you can as the current Chinese copies are hit and miss on quality. There is a carb rebuilder on the samba who has very good reviews. |

This. Second choice might be a 30/31 PICT on an adapter like I use on my own 1600cc DP engine.

Parades in Florida is nowhere like highway running in summer here in Arizona !!! VWs rarely overheat or run hot at low speeds or idle situations.
I personally recommend and use distributors with contact points.

I've had good luck w/the chinese carbs. The Pertronix SVDA distributor is a piece of junk, however, and I have personally experienced its failure and poor build quality. Many threads here documenting that. Spend the money you were going to use for the Pertronix and buy an original Bosch VW distributor restored by one of the pros here on the samba. You can't go wrong w/that combo.
I've had great success w/both of these restorers' original Bosch distributors.

It is a common misconception that air cooled engines overheat in slow traffic. They do not. That is a water cooled air flow through the rad thing. If in fact it does then there is something seriously wrong with your cooling system and/or state of tune and it will overheat 10 times worse on the open road ie. mouse nests in the cylinders/heads, rags sucked into the cooling fan, bad timing setting, extreme lean/plugged jets, that sort of thing.

^^^This!^^^
Or clean up the stock distributor if it's not a 009 and matches the carb you will be using.
I have not had good results with the Chinese replacement carbs at all! Find an original one to clean up and use.
