Evening, I might need some help. After I found out about the distributor and the engine is running, the valves are set up. I have read in the WHB and also dared to do so. I also got a few tips. I have only one question to ask: When releasing the towing lever through the cam of the camshaft you should measure this distance. According to WHB you should take “as wide a” lesson sheet as possible. u is “as wide as possible”. Is there a default? For example 0.5 or 0.35 or 0.8 ? How should the distance between cams and towing lever be so that I adjust the valve play correctly? The valves themselves are adjusted in stages 0.15, 0.20 depending on (inlet or outlet). But this must also be in conjunction with the distance from cams to towing levers. Please “brain” . Thank you.
