Mr. Gonnella - Yup, the is it or isn't it question is stooped. But it is fun and a diversion when the digest is slow. As for your idle question, the answer should be fairly simple: the carbs are not in sync with each other. One or more butterflies is open at idle, when they should all be closed equal amounts. Disconnect the linkage from the accelerator pedal, then loosen the bolt on the linkage between the carbs. The butterflies should relax to the same, equalized positions. Tighten the pinch bolt between the carbs and reattach the linkage. Now adjust your idle.

I haven't wanted to get into this is it or isn't crap because frankly it is stupid (stoopid) and irrevelant... The current Alfa V-8 is a Maserati engine by way of Ferrari so is it an Alfa? Oh and by the way Fiat owns Chrysler so the V-10 is a company powerplant just like the Ferrari. Just hope the Alfas finally come back to the US (please no SUVs)... NOW lets get back to the digest... I have a 1969 1750 Spider that will not idle on all four cylinders. Twin Weber 40s in place of the SPICA F.I. I've checked the compression, excellent on all four, valve timing correct and the car runs great at any RPM over idle. I've replaced the car blocks and the carbs are supposed to have been rebuilt. Working the idle adjustment will move the idle around the cylindere and the car will run on three cylinders, any three but not all four. It was suggested the engine is pulling enough vacuum to draw fuel into all four cylinder at 850RPM. I'm thinking I need to rebuild the carbs... Any thoughts?

No, they're not. With their religious adherence to the 45 degree V-twin, hey stand nearly alone. Sure, the other motorcycle companies grudgingly ave in and began producing engines of a similar ilk, but only because hat's where the money is, not because it's a smart way to build an engine. See also: "C'mon, dude, first one is free.") Without external balancers, here is just no way to dynamically balance a 45 degree V-twin. Had Harley ecided that brains, math and physics matter, they would have been building 0 degree V-twins since the 1930s. A 90 degree V-twin: now THAT engine can e balanced. And there are other companies--Moto Guzzi, Ducati, Honda--that ave campaigned that layout successfully for a long time. Ferrari and osworth? 90 degrees. Balance always wins. ich Wagner ontrose, CO ojave, CA ehachapi, CA nd points elsewhere... 82 GTV6 ------------------------------ Date: Fri, 22 Jul 2011 16:32:09 +0000 rom: "Watry, Andrew (LNG-SFR)" <[email protected]> ubject: [alfa] Spica air pump belt idler pulley wanted Anyone have some or all of the adjustment pulley assembly for a Spica Spider ir pump?

I assume t's an electric pump if noise is a problem. Maybe you could attempt to insulate the mounting system to reduce vibrations rom pump to chassis, and insulate the pump itself. Either wrap the pump or abricate an insulated cover? If it's in the tank, insulate the tank better on its mounts, and use some ype of sound insulating underfelt over the tank.
