No thanks

Pretty neat how we are, some of us, are a 1000+ miles away, have never met and never would have otherwise if it weren't for this internet and sites like these.
I get busy, real bust sometimes and I don't have the moment of peace to ponder it long enough.... so i lazily come here and ask for some opinions on it. Nice we can do that.

My idle keeps going down, the butterflies aren't open very much when its right, both sets are adjustable , I dial it in to 900 rpm , even on each set pri/sec blade almost 1 full turn on all 4 mixture screws...
Timing 25 locked.
The damn idle speed screw/s are backing off I believe. When I go to reset idle speed screws ...back them out....the blades are closed before a full turn out. It does this after freeway driving at 3500-4000 and some 6k blasts when passing. Car jumps into 100+ with ease. Gonna look at the screw springs, maybe mark them and drive it to verify.

Carb is about 14 yrs old....i think I'm going to finish building the 1050 I started yrs ago and just put off..

Armchair bomber, that's you.
Splain the "timing 25" locked to me , what engine ?
