Bought a 80% done project. 1.7 engine has been rebuilt and lots of new goodies installed. However I don’t know what heads, and internals were installed. Engine has never had oil in it and looks like jewelry with dual Weber 44s, new heads and powder coated tins. I’m on a quest to learn what I can about this new engine. Other than the carbs, only other info I’ve found is a number 850910 stamped on the heads next to an intake port. Any recommendations on how to learn what I have without taking everything apart?

Thank you for your quick insights. This is my first air cooled. Engine is not in the car. Have stainless heat exchangers and really big pipe exhaust system which is not installed. I’ll pull a valve cover and see if I can address some of those great questions. Are the venturis marked with size? Do I remove them to find the markings?

QUOTE(Robroe @ Aug 29 2023, 07:49 AM)  Thank you for your quick insights. This is my first air cooled. Engine is not in the car.

Are the venturis marked with size? Do I remove them to find the markings? The venturies are usually marked with the size @ the top,remove air cleaner and shine a powerful light down the throat so you can see . The number on the stock part is a raised cast in number , I have seen aftermarket ones with the number punched in, if you see 36mm which is standard supplied with the 44's they most likely will not run well as mentioned. IMO its really hard to find out much about the engine unless you can get more info from the seller ....which appears unlikely in this case ,cheers. |
