Re: 8 hp Mairner

Howdy, Lersia. The symptome you give are classic for an unvented or inadequately vented fuel tank. Loosen the cap and see what happens. If the problem goes away clear whatever is preventing air from getting in at the cap. If the problem doesn't clear up, pump your ball pump. If that clears it up you have a failing fuel pump or some restriction in fuel flow.<br /><br />Good luck.<br />JB
