Piaggio nrg mc3 air carbrutor idle screw and air mixture settings

Your best bet is to contact the importer parts dept and ask the question.

No fuel, or you lost spark. Check wire connections,especially the plug, cdi, and coil wire. Often the kill switch is off, or the kick stand safety switch is on.

hi buddy on the carb will be a screw this is the mixture screw turn this all the way in and unscrew it 1 1/2 turns out i will send a pic when i get home from work

Check air filter and exhaust. Is it possible that someone tampered with the bike?

also maybe sticky drive belt, not acting on the variactors properly.

check the timing its probally off by some degree. its located on the other side of the bike ( opposite side of the shifter) in the maintance manual it will give you the timing defree needed.

If its a 2 stroke try fitting "Brand New" Spark plug. If problem persists check plug condition as could have too much 2 stroke coming through via 2 stroke pump, Water in the fuel or poorly setup Carburettor.

>>The Following is the Instruction File for Setting the Air Mixture Screws. Any Input is Appreciated. The Procedure is the Same for 1 or 2 Mixture Screws, Just Use the Instruction File and Skip Over the Section with the Missing Mixture Screw ( Usually the H Mixture Screw).
>>Now Setting the Air Mixture Screws:
>>****Turn the Idle Air (L) and Main Air (H) Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Set the Throttle Full Open, Start the Engine.
>>Turn the Main Air (H) Mixture Screw Clockwise Until Proper Revs are Obtained. **Carefully Use your Finger and Move the Governor Arm to Rev the Engine (on Chainsaws and Trimmers Use the Trigger to Rev the Engine) Until you Reach Max RPMs (on Chainsaws and Trimmers, the RPMs are Not Set to MAX. Set to Max and then Reverse the Setting Screw 1/4 or 1/2 Turn. If the H Mixture Screw is Set too High; the Engine will be Starved for the Oil in the Gas and Damage the Piston and Jug/Cylinder) and the Engine is Running Proper at Full Throttle Up a Grade and for Chainsaws and Trimmers they Do Not Bog DOwn Under a Load. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs.**
>>Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required.
>>Now Set the Idle Air (L) Mixture Screw so there is No Hesitation when Rapidly Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****
