So, now i got new bearings for it, a turbo head button, OS P3 plugs and Sidewinder 20% fuel, i just had it outside on the street to try out my new truggy and i couldent get it to idle down as it should, after each wot run the engine would rev really high for a while, and slowly settle down to a normal idle, temps where pretty low, around 150F, so i tried to lean the hsn and the idle got even higher but temps didnt really go up, the highest temp i got was 175F.
So, what do i do ? what are the " stock " settings on the carb so that i can " start over "
Swede did you switch to 20% Nitro or where you running 20% before, If I was to guess and thinking that your carb needles werent changed and you only changed the button. I think what happened was your HSN is now rich because of the turbo button. So set your HSN for performance you may need to lean it and you should see the temps come up. Remember that you HSN also effects your LSN, so after leaning the HSN your LSN may now be too lean and you will need to richen it. Also remember to adjust your idle, usually run on is the problem of a improper idle gap masking a overly lean or overly rich LSN. You may want to set your idle gap at 1mm when you reset your needles.
Nitroluver that is why you should never use another engines internals in your engine or use go engine internals in other engines, it may look like it works but the tolerances could be way off.
