I know that I probably ought not to be mucking with my carb setup if I have not yet got the things back to perfect, but I couldn't resist hooking up my newwest mod (just arrive today). I bought a pair of volvo clam-shell air filter boxes on eBay. Both are similar to filter box on my dear departed dual-SU 145 (1972-1997 RIP).

The first has a simple cone-like intake to the airbox and a connector for the PCV hose about midway along the box.

The second box is just the cover (fits the same box) and it has some sort of primitive air-mass-meter thing on the end. It looks to be a temp-controlled flapper that pulls air through one of two openings depending on air-temp. It looks like it might be from an early P1800, or a very early 140 series.

[edit] According to the manual, it's a "Constant Air Temperature Device"

I went ahead and installed the simpler of the two filter boxes on my dual HS6s. I'm well-aware that a bolt *could* vibrate lose and lodge in the carb, but I had the same risk on my old reusable filters and I can live with the possibility.

My questions are these:
1) Is there any way I could use the flapper intake thing on my Amazon, and how would I set it up?

2) Are there any other risks/issues/problems/advantages of using a single filter on a dual carb setup? (Aside that the filter is just $7.00)

3) Do I really need that auxiliary heat shield on the front carb? (goes between the carb and the filter)

4) Can I use rubber gasket material (e.g from the hardware store) between the filter box and carbs? (more durable than cork or paper)

Thanks

You mean to tell me that Volvo makes cars that are *NOT* Wagons?!?
