Idle Tuning - is it rich or lean? I have a TSP225 on a 112 LSA. I've leaned out the idle quite a bit. Every now and then the idle will drop to around 500 rpms, and stay there for a few seconds...almost like the engine is dead. It is super smooth too - not shaking. Is this too lean or too rich (I think I'm about 50% leaner than stock from 400-800 rpms)? What kind of timing do I need at idle?

Sounds like you need to up the Idle Air values some.
I'm assuming you're referring to leaning it out by the VE table? If thats the case (don't know how you'd do it otherwise) then 50% will likely cause a hesitation off idle. 70-75% from stock is about all mine can take before it hesitates.
