Thanks hutchinstuff, very good info and glad to find that its normal.

On another note, after bending the stops back, I found out how many turns my high and low speed needle were set from the factory. My low speed needle was around 1 1/5 turns, and my high speed needle was, guess what, 1 1/4 turns! So much for "no tuning required from the factory" atleast you would think the HSS would be in the ballpark. They also claim that the stop would prevent from leaning the engine out to much. All it prevented me from doing was checking to see if the needles were in the ballpark.

Now I'm worried because I ran the engine when it was first breaking in lean because thats what it was set from the factory. It runs fine now but I'm worried about the long term life of the engine.

After reseting the needles 1 1/3 turns for the LSN and 3 turns for the HSN I ran the engine and got it tuned properly. Now it runs great! I ended up with 1 1/4 turn for LSN and with 2 1/2 turns for the HSN.
