77 9.9 with 15hp carb.<br /><br />After getting it to run great, lately I noticed at idle it'll burp every few seconds, like the spark plugs don't fire once. <br /><br />Forgive my sound effects...<br /><br />Rrrrrrrr...brrrrrrrr...brrrrrrrr<br /><br />Usually this will drop my rpm's enough to almost stall the motor, but if I give it some throttle or put it in gear it goes away for the most part. <br /><br />New coils/CD/plugs/carb rebuild, fuel pump etc.<br /><br />Wrong plugs? QL77JC4.
