Engine sound was created by gordone
Prepare for weekend trip next weekend.
What do you think about the sound?

I have the mic first on one side of the engine and then on the other side, over sparkplug 1 and 4.

I have checked the valve today, and two was to loose, or almost outside the limits...
Maybe the sound will be tter now?
I don`t think the sound was bad, but it was maybe some valve sound ?

Gordone, do you have re-check the carb sync??? I my opinion the engine idle rev is a little to high too.

I have not check carb sync after re shimming the valve, will do that. Must take it on day time, to much sound for afternoon between the houses :)

The RPM say 1 on idle, but maybe it`s off ?

What is the benefits of having lower idle?
