While what you say is true and the carbs will have varnish from evaporation and from chemical breakdown/oxidation of gasoline, tolulene and xylene are excellent at dissolving that and also burned carbon on rods and pistons and cylinder heads. It will also remove baked-on oil from Beetle cylinder barrel fins and cases. These two compounds are amazing. It would take a steam cleaner, with special detergent just for cleaning engines prior to rebuilding, about 20 - 45 minutes to do what they can do, without dismantling the carbs (and the intake, for that matter). But if there is rust debris from the tank, it can't remove it from clogged passageways. That takes - usually - soaking, rinsing, and compressed air. If you have a newer car, the aerosol can of stuff that one purchases to clean the intake manifold (something the dealers charge $30.00 and up for and it only takes about 10 mins), at least one of these two are in it. BTW, Coke used to use (may still) xylene to extract the flavors for their Sprite. They can't remove all of it, so when you drink Sprite - and maybe 7-Up as well - you are possibly drinking xylene.

Ditto all above. We tend to champion Seafoam because it can solve a lot of niggling minor carb problems, but it's not the magic elixir you'd think from reading the raves about it. I read somewhere that gas starts to degrade in as little as 3-4 weeks time, progressively turning to a syrupy consistency as the volatile organic compounds in it evaporate. Seafoam can probably do a good job at reversing that process during that time. But the longer a bike sits without being run and/or without gas stabilizers in use, the thicker the syrup and the more resistant to Seafoam-type products it becomes. It will eventually become a hardened "varnish" (so-called because that what it looks like), ultimately crystalizing into hard granules. So the conventional wisdom is correct. Carbs probly need a thorough, surgical cleaning. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
