WEBER IDF 44 CARB SETUP

 
 

To mount the manifold on an EVO engine I decided to make 2 aluminum ears welded directly to the manifold. We hand sawed, filed, drilled and bent 2 ears from aluminum strip, the bends are to allow the manifold to expand and contract with the temperature differences in the aluminum engine without cracking. We also made the small part to hold the outer throttle cable. Before welding we pre-polished all the parts so we would be able to get in all the hard-to-reach places and to get a cleaner weld. We were lucky to have an EVO engine we could use as a template and Aad welded the ears with all the parts fixed on the engine so all would fit perfectly. We ran out of time before we could weld on the cable-holder....

 
 

And finally, the finished set:
