Hello, I bought a new “toy” today. Unfortunately there is a problem with the new Holley carburetor. In the stand it runs completely unevenly. When it starts it runs nicely round but breaks in, so that I have to keep it running with the gas. The seller did not connect the vacuum hoses properly again. It must have to do with the cold start of the carburetor and the early ignition at the start. Now good advice is expensive. Maybe one of you has an Ansc Hlusplan. At the front of the engine are 2 valves with 3 outputs each. (connected to the water keislauf) On the side of the air filter box a white and a blue plastic part with 2 connections each and at the bottom of the air filter box a metal valve with 2 outputs. On the left side in the engine room a metal can (as large as a Coladose) with 2 outputs and of course on the new carburettor a lot of connection possibilities. already many thanks in advance.
