no its not a noob question, this is how i set up my trucks , 1 the pinch test with the truck warmed up pinch the fuel line as close to the carb as posible ( i pinch the line about 3 inches or 5 cm away) it will take 5 to 6 seconds for the engine to die then the lsn is ok if not richen the lsn untill it does. 2 once that is done you need to adj the idle the engine off remove the filter and it should have an opening of 1 to 2 mm ( 1mm perferably) and once thats set put the truck on blocks so the wheels are off the ground give it some wide open throttle ( at this point the air filter is back on the carb) if it dies at wide open then you need to adj the hsn the one next to the fuel line richen it up, if it sounds like its not hitting top rpm then you need to lean it out (turn the needle in).this should get you in the ball park .
