Now that you have cleaned your filter and de-restricted the brass plate from the 17.5mm Dellorto PHVA Carb on your 2005 Piaggio Typhoon 50cc 2-stroke Hi Per 2 engine, it is finally time to do some carburetor tuning to make the bike perform smoothly and make use of that extra air/oxygen into more power.
First step, adjust your idle mixture. Idle mix screws are either an air screw or a fuel screw. The one shown here is an air screw where turning it clockwise would richen the mixture. It is recommended you start off your mixture rich and work your way down for 2-stroke engines as lubrication is a component of your mixture. Therefore I turned the idle mix screw all the way in (clockwise) and backed out 1/4 of a turn to monitor improvements in engine response and idling rpm. My final setting was 3/4 of a turn out. Engine response was crisp, there is not a significant smell of unburned gas at idle and header temperatures were relatively stable.
Stay tuned for the next episode part 2 of carburetor tuning as I show you how my scooter progress from a scooter that holds up traffic to one that can zip around rush hour traffic with no problem!
