I am trying to piece together a 1.5L carbed engine. I got the engine but it has just a long block, so I am piecing accessories little by little. I got intake and exhaust from FleaBay, and I am talking to a vendor who is selling Redline Weber carburetors. And here comes the rub: The Webers that he is selling are listed as compatible with whole bunch of cars and engines (124, 128, 131, and engines from 1.2 all the way to 1.8), but those carburetors are apparently NOT compatible with X 1/9 intake? Seller is saying that the bolt pattern on those Webers comes in either 92x45 mm or 80.7x40.6 mm. As far as I can measure, the bolt pattern on intake that I have is 88x47mm (center-to-center of the hole). Intake is a non-EGR, and fits on the head and with exhaust manifold correctly. No pic as I still dont have the carb yet. I was under the impression that base of the carbs are standardized?
