Motor scooter engine trouble?
Sunday, June 6th, 2010I have a 150 Avanti motor scooter...starts and runs good untill it get hot! The starts cutting out and missing...and is very hard to get started again..and keeps dieing. Dealer has replaced plug twice and adjusted carb to a richer setting..to no avail. Is it a gas flow problem or a spark problem? Seems the worse after pulling a steep hill. Any one have any suggestions?
