RE: Savage break-in, PLEASE HELP
The idle speed usually increases when you run too lean not rich. As for the engine not behaving when you stab the throtal after idleing this is normal. You are running (or should be) very rich "standard" settings on both needles an this causes a lot of fuel/oil to pool in the bottom of the engine. When you rev it the excess fuel and oil gets pulled into the engine and causes it to stall. I may not have the exact terminology right here but what i am getting at is if you let an engine idle for a minute or 2 and then try to move WOT the engine will usually stall even though it will carry on idleing fine for another couple of minutes.
This is why each time you adjust your needles after break in you should always make sure that you take it for a quick spin up and down the road and not let it idle for more than 10 secs before you test the throtal response otherwise you will find the low end is unresponsive and keep adjusting the needles when in reality the needle could be fine and excess fuel sitting in the crank is causing the bog
Hope this makes sense
