Vespa PX 150 Fuel and Carbon issue

처리 내용

Your experiencing fouled plugs. Fouled plugs have carbon buildup that grounds the electrode of the spark plugs over the ceramic with carbon. The carbon buildup occurs because the AFR (Air Fuel Ration) is too rich. This makes the combustion process, when you fuel is burned, too cool. Since combustion is too cool carbon buildup occurs on your sparkplug and now you can't start your scooter. There are a few things to check and most of them involve cleaning up your carburetor and your air intake. Validate that the NGK sparkplug that your are buying is the correct one for the scooter. If the plug is too 'cold' because it is incorrect you can experience plug fouling. Clean your air filter. Make sure it's not too restrictive. You best bet is to replace it if yours is dirty and clogged. Purchase a foam air filter you can clean and re use if they are available. Points are cheap and the condenser can go bad and not provide enough electricity to your coil to have a good spark. A good way to eyebal
