Re: A lot of smoke

Re: A lot of smoke

Herty<br /><br />I use the same technique and start mine every couple of weeks. Where I live, it doesn't get real cold (No Winterizing) but I like to keep it lubricated inside and run fresh fuel through the carbs to avoid gumming up.<br />Mine blows dark (petrol) smoke and chokes up the carport, but settles down after a while. You are only supposed to run them @1200rpm on the muffs so you not really blowing the cobwebs out.<br />Plus, the engine doesn't seem to have the same resistance as it does in the water, so it idles like a Harley. But in the water it's much quieter.<br />Note**** Buy yourself an inexpensive low amp battery charger to keep your battery up. The periodic running at idle will take more out of your battery to crank, than it will put back. The Outboards only have a low trickle charge.

As Andy mentions the biggest benefit is keeping the carbs crud free.<br /><br />I have been hanging around here for over a year and I'd guess that %20-30 of the motor problems are crud in the carbs related.
