Buy A MANUAL (a good merc dealer should be able o tell you the year of your motor)missing can be caused by lots of things so do the following:<br />Check compression,check spark,clean & set up carbs/float level etc also check needles & seats are closing properly.New plugs & synchronize carbs/ignition the manual will tell you how.<br />Should solve your probs.good luck
