Hi,Julian,and WELCOME to the "'Bolt"! Old gas is usually the "Gremlin",when it comes to performance issues with an old vehicle. These things weren't designed to run on un-leaded gas,either. you may need to clean the tank,blow-out the fuel lines,and replace the fuel pump/filters,and rebuild the carburetor,before you get it running right. Check out the "Engine Shop" thread,and you may find the answer to your questions there,or,feel FREE to submit a "New Topic",if you don't find your question posted. All kinds of topics,here,and all kinds of help!! Happy New Year!!
