[QUOTE="BassBlaster, post: 313236, member: 2865"] Decarbing is just cleaning all the old built up gunk from inside the engine. It is done by pouring an entire can of SeaFoam into a couple gallons of gas/oil mix and running the entire mixture through the motor at WOT. I did this before changing the plugs as it fouls the plugs up pretty good.Some people will tell you not to do this with these old motors so use your own discretion. I did it because I didnt know any better and was told too. I didnt damage my motor in any way and I got lots of black crud out of it. It is said to really increase compression on a motor that has low compression also. [/QUOTE]
