Re: 28 HP Evinrude BACKFIRE
Does it sound like a firecracker or just a cough? Going away when warm sounds like it is coughing.<br /><br />Backfires are generally caused by electrical issues. They can be cause by mixtures but my money says you will not fix it by tweaking the mixture. If it is coughing, then mixture is probably the culprit.<br /><br />If that 28 is an old one it will likely be traced to a bad condenser. Easy to replace and cheap to buy.
