Keep Dellorto DRLA 45s and Bosch 009? Options

[98101]

I suddenly find myself owning 1970 4-cylinder 2.4 with Web hot street Cam idles nicely and pulls hard at WOT. Part throttle response is not great, often with carbs coughing and even backfiring on trailing throttle. My use is mostly street, so I'd like to get this part throttle stuff sorted.

Here's pictures of the stuff that's in there now. I guess that's the infamous Bosch 009 with no vacuum advance and a PerTronix 1847A. The carbs are Dellorto DRLA 45s with short velocity stacks and these tall foam things that don't seal against the air cleaner housings. I'm willing to learn about the carbs but I don't have much confidence in the 009 for running nicely on the street. Please correct me if I'm wrong about any of this stuff.

Also from other threads I gather that switching to EFI such as MicroSquirt would cost $5K or so ... though I'm not ruling this out completely. Correct me if I'm wrong about that.






Is this kind of linkage OK?


Here's the idle you may have seen in another post:

Any help you can provide is appreciated!

Bought a $75 used dual point Mallory and converted it to a Pertronix II.

Do you remember which model Mallory it was? I’m guessing the dual point feature doesn’t matter for the PerTronix II, but my guesses seem to be wrong half the time.

Mark, where do you get your jets and air filters for your Dells? Someone can tell me if I’m wrong, but I can’t see how the foam wraps my car’s previous owner was using would stop much of anything.

There are always a few Mallory VW Distributors for sale on Ebay. I don't think it matters whether you get the dual point or the single point model.... the entire point plate gets replaced as part of the Pertronix. Mine is part # 2554101. Here is one for sale now:

The filters came from CB Performance. They are the 3 1/4" and clear the rain tray.

All of the carb parts came from a guy that has a web store on Ebay. I think its called ALPHA1750S ....he is in Italy and sells most every DRLA part you could need.
