Re: seafoam
It is naptha and isopropyl alcohol with some oil. That's it! Nothing magical about the stuff. Find some carb cleaner with the exact ingredients or buy the naptha at a paint store and the alcohol at a medical supply. The alcohol has to be the 99% type.
If the mixture is intended to be used only as a gas tank additive, and NOT sprayed directly into the carbs, is is OK to just add Naptha to the gas tank or just add 99% isopropyl alchohol to the gas tank without both being used at the same time?
Also, if it is OK to use Naptha or 99% isopropyl alchohol seperately, what would be a good ratio to use for adding to the gas tank?
I speculate that the oil addditive to the mixture would be important if the mixture is going to be sprayed directly into the carbs but not important if the Naptha or 99% isopropyl alchohol are added to the gas tank for an oil-injected motor. Also, I speculate there is no chemical magic to the combination of Naptha and 99% isopropyl alchohol and that the Naptha and 99% isopropyl alchohol can do their own thing without needing to be in the gas tank at the same time. Am I speculating well?
Thanks for any thoughts
