Smoke Coming out after corner
If there doesnt seem to be enough smoke coming out thru a corner which is a big thing to have, should i adjust the low or high speed. Im guessing the low speed. And should i richen it or lean it out to create more smoke. Im pretty sure i should richen it but then does that mean i have to adjust the high speed once i do that?

With a name like that, I would listen to him
Smoke depends a lot on the fuel. Fuels with lots of castor will smoke more than a low oil content, mostly synthetic blend.

Rich = More Smoke, Cooler Temps
Lean = Less Smoke, Higher Temps
I would richen the HSN by 1-2 hours and see how it reacts to start. Every engine/tune is a bit different. The HSN controls overall fuel delivery to the engine though. The LSN only controls fuel delivery at idle to maybe 1/2 throttle or so.
Either way....you need to richen something if you wanna see more smoke ;-)

Low speed needle is really a bad name for it. It should really be called an Idle Mixture adjustment. Speed doesn't really matter. The moment you open the throttle, the needle pulls out of the seat for the LSN and now the fuel is only restricted by the HSN.

Yeah the LSN only has an effect on the mixture until the needle on your carb slide comes all the way out of the slot it's seated in. Once it's out...HSN is doing ALL the work for mixture. Some carbs the needle is fully out by 1/4 throttle...others...1/2 throttle. Just pull your air filter off, turn on your rig....and operate your throttle and make a mental note of when the needle pulls completely out of it's sheeth. When it's out....any throttle position LESS than that is the LSN kicking in....anything MORE is the HSN.
More guys mis-tune their low speed though.....
