| Methanol gel problem | Login/Join |
| DRR Trophy |
The question I have is for all you guys running blow thru alcohol carburetors "Do you experience a problem with the methanol fuel gelling-up after the car has set for 2-3 weeks between races?" I have (2)cars both with alcohol carbs, 1-naturally aspirated and the other with a pro-charger. The fuel in both came out of the same drum. The pro-charged car gels the fuel if left in carburetor, the NA car fuels stays fine. Anybody else have this issue?? | ||

Are you running lube? Do you mix it in your drum before filling jugs? If so, quit it. I mix a cap full of lube per 5 gallon jug when I fill jugs. Also, I do not run lubed fuel all the time. You don't need as much as your buddies tell you. Jeremiah Hall | |||

Jerimiah, How does the lube cause that problem? I have never had a problem with running lube in my fuel. I am not using a blow through though. Are you saying not to do it in a blow through situation only?

I do run injection now, but I have had that same issue when running a alky carb naturally aspirated. Quit running as much lube and the problem went away. I normally use the Manhattan Oil "power plus" lube. When I started mixing by the 5 gallon all my issues have went away. I learned this trick from many others that were facing the same issue.

Wow, I think I would change lubes. I have always run Klotz Uplon 1qt to 55 gallons and never had a single problem. ____________________________ 2017 and 2018 Osage Casinos Tulsa Raceway Park No-Box Champion 2018 Div4 Goodguys Hammer award winner | |||

I have been running the lube and mixing in in the drum, but only 50% strength. I'll try your method Jeremiah. Thanks! | |||

I do not disagree with this, but I also feel that only enough lube is needed to keep the fuel system in clean working order. The way I do it, 1 qt has lasted about 5 drums of fuel. Jeremiah Hall | |||

Make sure to keep your drums sealed, and out of weather. Alky will pull moisture out of the air, and has also been known to cause issues like this. I keep my barrel in a climate controlled garage, and try not to let fuel set in jugs for extended periods of time, but if I do, it doesn't bother me because I will not put lube into the jugs, until I am ready to use them. Put a cap full in, shake the jug and pour it in. Jeremiah Hall | |||

What do you mean by gelling up in the carb? 72 Nova "Hooptie" | |||

It changes from a liquid to a gel or solid. It takes on the consistency of like wheel bearing grease. And when this happens the floats stick, the carb floods and the only way to fix the problem is to remove the carb, totally disassemble it and remove the gel. | |||

I run Klotz 16oz per drum, been doing this for 5 years with no issues runnig Rons injection. Mixing the same with blower engine | |||

This is my guess, I may be totally full of crap. The Procharger is introducing a lot more moisture to the engine than the one that has the naturally aspirated carb. Therefore the gel probem is exasperated. From my own experience with alky carbs and fuel injection, the injection was much easier to maintain than the carburetor. I also ran one capful of Klotz Uplon in each five gallon jug with no issues. It helped a great deal on the carburetors. I don’t know about running a single Terminator with a Procharger. You might contact Scott or James at Killerrons and see what their experience has been. Several of us discussed this at lunch today. I am still amazed that a blow through carburetor can support the kind of horsepower that they will. My friend Bob removed his carbs (not blow through) from his roots blower setup on his T/D and went to a twin Terminator setup and I can tell you they are working better than the carbs. Good luck and let us know how things work out! Clowns to the left of me, Jokers to the right. Here I am....... | |||

It's a natural reaction for Methanol. Marvel Mystery oil is an excellent treatment. If the carb is going to sit for awhile squirt some Marvel down the bowl vent.

Paper cartridge fuel filters can cause it, the glue dissolves and will collect in the bowls. I've heard some lubes can do it, Klotz does not. Marvel Mystery oil does not mix with Methanol, it will separate. You might want to take the carb hat off after you race if it's not too much trouble. | |||

Remember this. Methanol is a chemical. A hydrophilic chemical. Therefor, it may absorb water, but it doesn't turn to a gel.. If you have gel, it is from something else introduced to the fuel. Don't put stuff in your fuel.  ΜΟΛΩΝ ΛΑΒΕ | |||

Thanks for all of the feed back, I appreciate it. I've got a better idea of what to look for now. I don't run a paper filter so that's not an issue. I had also considered the idea of moisture getting condensed via the pro-charger and was curious if others have had the same issue. Thanks! | |||
