i have an 85hp force when trying to start it backfires even shoots fire out of the exhaust.could this be the timing? if so where can i get info on this matter. or could it be something else. motor ran fine last year but when trying this was hard to start so like a dummy i tried some starting fluid and thats when it started backfiring. now everytime i try to start it backfires and shoots fire out of the exhaust is there a easy solution? or where can i get a manual or something on setting the timing on a force<br />on the web.<br />any help on this matter would be a plus.<br /><br />ps. i quit using the starting fluid !!<br /><br />thanks
