Chevron product Techron (not sold in many stores, advertised in Autoweek,
other magazines in the classifieds) added to the gas cleans the carbs,
valves, cylinders. call 1-800 techron for one vendor. You need to buy a
case, but it's good for all your cars, especially those with fuel injection.
Techron is an ingredient in some other products, but you want the full
strength stuff.
General Motors - Mr Goodwrench has a product you either pour or spray into
the carb (comes both ways) with the engine at idle till it's all gone and
then shut off the engine for some minutes. Re-start and the carbon goes out
the exhaust. I don't remember the name, but if you're interested email me
and I'll look in my garage - I have some in stock.
Both the above were highly reccomended by a Champion Spark Plug engineer I
sat next to on a plane trip.
