Hi all,<br /><br />In a boating forum I oftnen use, I mentioned how I cleaned my Nissan carb using car cleaner (see my previous post). One participants who seems to have a lot of experience with small engines wrote the following:<br /><br />"""Please don't - - - - <br />run carb cleaner through your engine while it's running. It is a great solvent and will wash the lubrication right off of everything moving just when it needs it most. I hope I don't have to explain the consequences of that.<br /><br />As gasoline dries it leaves solid crap in itsplace. This stuff blocks tiny air and fuel passages resulting in rough or no idle, and occasionaly, if it's realy bad, no run at high speed. No fuel = no run.<br /><br />Best attack? pull the carb off, disassemble, spray with carb cleaner, blow out with compressed air, put it all back together. DO NOT clean jets or passages with wire or any other ham-fisted method.<br />We used to get droves of motorcycles in each spring at the shops I worked at because the owners left gas in the carb over the winter. Big bucks to remove and clean a 4-bank of carbs, or even a single for that matter. I've done it more times than I could begin to count on all kinds of equipment. """"<br /><br />What do you think?????
