Timing For Single Weber CU engine

[LeeCarey]

I have a camper which in the past has been fitted with a single Weber carb conversion and I have just had the need to fit a new distributor because it had become faulty (071905205). The engine now starts fine but I want to make sure that the timing is correct. Having read the Wiki etc. I am a little confused as to what the timing should be set to as I understand that the carb fitted could effect the settings.

Any help would be appreciated

The carb doesn't affect the timing the type of distributor does and how the vacuum advance/retard is plumbed in.

You may be confusing mixture settings with timing settings.?

It has a single vacuumn pipe for advance.

I guess I will bypass stabiliser unit and set it for around 7 degrees @ 850rpm with vacuumn pipe disconnected, as a starting point.


Thanks for replies

That's the correct timing for single vac, actually 7.5 deg then check the maximum advance over 3500 rpm normally 25-28 deg maximum of 32 deg.
