thanks mate. i tested the fuel tube from pipe to tank. no isssues. i recently changed my tank as the old one was broken. i'll "sink test" it tommorow. this engine has been really good to me so i hope it hasn't died!
maybe my fuel isn't of the best quality. when there is a black ring close to the top of the sleave does this mean my fuel is no good...or that i'm running it hot?
