Default sea foam

I hadn't started one of the cars for a couple of months, went to start it and it would not continue to run, ran fine on a shot of ether, then quit even, if I gave it the gas. Looking the carb over, I noticed that the accelerator pump was not working. Put in a new diaphragm, still no shot of gas. Brought it to my carb repair guy to have it boiled out. Got it back the next day. When I walked in, he said, I see you are using Sea Foam. I said, yes, I had just put some in about a month ago for the first time, how did you know? He showed me some pictures of small balls of a jelly like clear stuff in the float bowl that he said was sea foam and that was clogging up my carb. He has been rebuilding carbs for over 30 years, so he does know something about them. My cars run only 93 octane 100% pure gas. He recommended putting in a gallon or so of gas in the tank and running the engine every week and adding to the tank to always have a gallon only in the tank before I am ready to run the car on a normal basis then fill it up. I sure some of you have had good luck using sea foam, I did not. Just a heads up, as that time for winter storage is coming soon.

I have never put additive in my gas if it doesn't have ethanol in it, and have not had a problem. But of course, in my area it doesn't sit for more than a month without being started and driven.

I've used Seafoam in my newer cars to clean the injectors, but not to treat the gas. Now I sure won't! Thanks.

I've been faithfully using seafoam for over 20 years. NO fuel related issues using this product and I've used it on a number of cars that sit for months/year. I always end my season filling up the tank, pouring a can of seafoam in, drive it around to get the treated gas into the carb and park it. I never do the winter start up routines some do as I don't want to introduce moisture into my system and not eliminate it by driving. Again, no issues with this routine for decades. My dad buys it by the case and I buy it by the gallons. My dad puts it into every fuel up for all his cars since they are driven so infrequently.

I tend to agree with 66gtk. Seafoam has been around since 1942.
I can't find any negative articles on it. However the jelly is normally an issue seen with Old gas and literally a slew of (I'm too lazy to count) articles on the subject. Much more prevalent nowadays with Ethanol fuels.

You living in Florida (I'm a native) it can be exasperated due to the heat and humidity.
Some dry reading on the subject. (needs coffee)

On finding Truly 100% gasoline this site will help.
