Jim, I had a 6 year old Formula SCCA (Mazda 2300) that I did a leakdown on. Had 95% on 3 cylinders and 60% on one. Ran half a bottle thru the throttle body @ 2,500rpm. That cylinder came back up to 92%. probably carbon on the exhaust valve.
Water misted in might have produced the same but the SeeFoam worked and the car ran great in the next race.
I had similar results with MMO.
Engine not started in 15 years. When it awoke, it was running on several cylinders (maybe as few as 3, definitely fewer than 6 (of 8)). MMO in the oil and in short order it was running on 7.5 cylinders.
BTW, saw one of your injection rebuilds on a 58 a friend of mine just bought.
I know the unit. I spoke by phone to Joe just the other day.
What you saw isn't impressive unless you saw how it looked when I first got it. It looked as if it could have been dredged up from the Titanic.

In any event, it's now a sweet FI unit.

The car is rough but the body is really nice. At least it's "all there".58 fuelie field find.

I'll be on Reno-Fernley on Saturday.
It's supposed to be a 16K mile car. From the look of the inside of the FI unit, I can believe it..... it was pristine. (probably due to the seafoam) The car must have been stored outside forever, tho, for the amount of corrosion there was.
Enjoy Fernley. Friend of mine once described that track as "diabolical".
My two cents....Techron Fuel and Carb Cleaner is good stuff. Eliminated the knock from a Crown Vic's motor after the ford dealer messed with it using their cleaner process. They cracked the intake manifold in the process (composite material). IT STILL KNOCKED. After they replaced the manifold I wouldn't let them mess with it any more. Instead, tried two bottles of Techron in two consecutive tanks of gas. Knock disappeared and never returned. I use a bottle on my cars at least twice per year.
Seafoam is the only product of this nature which I've ever tried and actually received a proper result. Definitely not a cure all for any issue, but I do think it helps clear some impurities from a fuel system and delivery system! I've used it on several occasions when a vehicle was running a bit rough (usually from long term storage) and Seafoam in the tank helped smooth things out and improve the running...My 2 cents...Worth about 1 cent...
I generally regards all such products as snake oil but have to admit to having positive results with Sea Foam. I've soaked stuck Mercury fuel injectors in it and had them start working again. I had one of my boats with newer Suzukis developing a problem where they would start then die and have to restarted again, sometimes twice more. After one tank with a can of Sea Foam they stopped that behavior.

That's using the product for it's original 1940s purpose but on today's hardware.
The IPA (iso propyl alcohol) is a very polar solvent which will dissolve the water that condenses in your fuel system over time. Marine vehicles would be more prone to getting water in the fuel systems. Water will not combust, but when dissolved in enough IPA, the mixture will burn.

water doesn't 'dissolve', but it will get 'absorbed'
Of course we could now debate the point that the same group that just hates E10 because it absorbs moisture apparently loves Sea Foam- which absorbs moisture.

Good call Mike! We all love E10 and can't wait for E15 and E20.
I say it is a lot like going to the doctor. If the doc throws enough pills at you, one of them is bound to work. Human body and internal combustion engine - too many variables.
I will say this to the credit of Seafoam. Had the Jet Skis at the lake this summer. One was running like crap. Had new plugs and fresh fuel. Hard starting, would stall, run some more on full choke, etc, etc. My buddy asked me if I ever had water get into the fuel through that small hole where the plastic cover used to be on the fuel cap. I made a mad dash to the local parts store as he was closing. Dumped the whole can of Seafoam in and within 10 min at ran like a champ and did so for the entire week.
I have no idea how much water was in the fuel or carbs but I can assure you that it burned every drop of it.

Well, maybe it's because E10 in a 20 gallon tank equals 2 gallons of ethanol alcohol, which has the potential to absorb a heck of a lot more water vapor out of the atmosphere and induce it into a fuel system than does the few ounces of IPA in Sea Foam, which is designed to get rid of water which is already there................
Not to mention the corrosive effects of 2 gallons of ethanol on old cars' fuel system parts.............
Or maybe, just maybe, the whole panic over ethanol is really a non-event, just like the removal of lead back in the '70s.
Here's the sum total of 20 years damage to the inside of my gas tank after being fed nothing but E10
The horror.
I could show similar results pictures of many carburetors Mikey, If I was motivated to take pictures and post them.
Of the many carburetors I've been inside of in the last 30 years, I've only seem one that was corroded. It was mine from new and had been sitting idle on another location and never had E 10 run through it. Another carb I've had apart recently was gummed up big time. No history on it as I just bought the pos but once cleaned, it worked fine.
Corrosion and gum in carburetors have been part of the maintenance drill since there have been carburetors hasn't it? I remember back in the early '50's, ...............................
I understands Sea Foam is very caustic and can actually etch metal...maybe good for an occasional clean up but might be contraindicated for everyday use.
