We have had long discussions about my Fl 70's idle. I ended up changing the fuel and adjusting the rocker arms. The problem got much better but not disireable. A friend told me to add a few washers between the engine and the mount to tilt the engine slighlty from the horizontal position it was sitting at. Well, i did that and today when i turned the engine on it idled so low that i couldn't believe my eyes and that was without the onboard starter forcing it to run. When i opened and closed the air-bleed whole i could actually hear the rpms change at idle, this has never happened before.

I am very confused now, what has caused my engine to idle, when it didn't idle before?
This could help me in tunning other engines in the future
