Shurkey, you're damn smart. Can you summarize what that means to someone who dosent know much about chemicals. Obviously it's not a very environmentally solution, dont drink it. Haha.
In my limited experience with these products they have worked for me. When I first bought the burb it was tapping like a *****, some routine mmo in the crank case along with some shorter oil changes made it go completely away. Now it purrs like a kitten still 10 years later.
With the seafoam I used max does in the fuel for my 10hp 1963 johnson when it was acting like it was running on one cylinder, within a few minutes I was back up on plain heading to a fishing hole. Worked for me.
But that's it. I don't see anything wrong with those. Rebuilding my burbs engine at the time when theres no way I could afford it because its tapping? Carbon build up. Dad said put the peddle to the metal, keep it straight. I'm like Dad we cant do that anymore.... his generation is responsible for all the damn stops signs in the town I'm from. But hes right, to clean the carbon out.
Shurkey, I have heard about the water trick but not until after i had already done it. A buddy said take a spray bottle and spray the intake with a mist until it dies. Get it going again and it will puke out all the bullshit... gee I think I'd rather burn it then send it toward my O2 sensors. But I dont know I am FAR from an expert.
