I don't think it's quite right to call this the "low compression version of the 1500S" since I thought that the S specifically stood for the high compression engine. I would simply call this the normal or low compression dual carb engine. Did your car come with the 1500S logo? Do you know for sure that it came from the factory this way? I'll recheck my sources, but I'm pretty sure that they only show the M240 as the low compression version of both the dual carb and single carb engines. I can look at that again tonight. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
