Rodney Bullock Posted June 19, 2014 Report Posted June 19, 2014 Hello all, I have not been on the forum for a while due to my restoration of another Mopar, The charger. I have been working on it for some months with very little progress. The Plymouth has been sitting in my studio for little over a year. I did pull it out to drive last week and the car would barely start, when it did it would not rev. IO feed gas to the carb and it ran. it had such a foul smell to it. I have never smelled anything like it. The fuel was green when I pulled the carb apart. The chemical must have eaten the little plunger up as it was half the size it usually is. I pulled the carb and sent it to Mr. Isgro for rebuilding. I guess the gas was real old. I wonder after I get the carb back should I drain the gas of just run it out? What do you guy's think. Quote
soth122003 Posted June 19, 2014 Report Posted June 19, 2014 If the gas is green, that is probably mold from the ethanol. With old gas like that I would drain it and maybe flush the tank. When gas breaks down like that what you are left with is a thick varnish type liquid. not good for any engine to run on. Quote
Dodgeb4ya Posted June 19, 2014 Report Posted June 19, 2014 (edited) Varnished gas can cause the valves to stick too. Drain it all out. I Had to do this on a 51 Stude convert today. I still smell like varnish! Awful nasty stuff. Edited June 19, 2014 by Dodgeb4ya Quote
Dan Hiebert Posted June 19, 2014 Report Posted June 19, 2014 Definitely drain the old gas, it'll only muck-up your engine. I'm curious what turns it green, but am skeptical that it's mold, kind of harsh conditions for even that stuff to grow I'd think. I had old gas in the Terraplane, but the only place it was green was the carb and the fuel filter bowl on the fuel pump. The gas in the tank reeked, but it wasn't green, it turned brown. Still works good for cleaning parts, but not much else. Quote
Don Coatney Posted June 19, 2014 Report Posted June 19, 2014 I did a search and found many instances of black mold around gas storage containers. I have that black mold around the fuel door of my pickup. But I was not able to find any reports of green mold associated with ethanol enriched gasoline. Quote
Joe Flanagan Posted June 19, 2014 Report Posted June 19, 2014 Rodney, when I got my 56 Chevy, the gas in it was really old and had turned into something like varnish. The best way I can describe it is that it was kind of like molasses. I had to soak everything to get it clean. I'm sure yours isn't nearly that bad but I'm with the others. Drain the tank. Glad to hear you're working on the Charger. Quote

greg g Posted June 19, 2014 Report Posted June 19, 2014 Hey Rodney good to hear from you. I was wondering why we hadn't heard from you in a while. How much gas is in the Plymouth? If it's between a quarter and half tank I might put some of that new Stabil stuff in it fill it with fresh non ethanol gas and drive her empty. Then change the fuel filters and refill with fresh. If it more than half, you are probably better off draining it, and starting off fresh. You might want to give you points a couple swipes with a dressing file just to clean off any corrosion that might have accumulated there. http://www.sta-bil360.com Quote
Plymouthy Adams Posted June 19, 2014 Report Posted June 19, 2014 chunk that gas like last nights dishwater... I do not think that Stabil will salvage gas once gone bad..it is to prevent the going bad...most all small engine makers warn not to use any fuel with alcohol if over 30 days old...there is a reason for that...Dodgeb4ya nailed it with the sticking valves..will cause them to stick in a skinny minute..spend the nickel on good fuel and erase that as a prossible problem for other issue that may arise when you get the coupe started and running again...

desoto1939 Posted June 19, 2014 Report Posted June 19, 2014 I also agree get rid of the old fuel. Put clean fuel in the tank with stabilizer added since you are not running the car alot. Recommend that at least turn the car over and start it every week when it is sitting inthe garage and also pump the brakes to keep them free. This ethinol is bad and now they want to have us use 85% based ethinol gas. The antique car hobby will be in big trouble. They just want our old cars off the road and tobe crushed and out of site. Just think of how many small and also mid sized companies would be affected if they trashed the old cars? Rich HArtung desoto1939@aol.com Quote
ChrisRice Posted June 19, 2014 Report Posted June 19, 2014 I'm glad non ethanol is readily available in my area. Quote
Plymouthy Adams Posted June 19, 2014 Report Posted June 19, 2014 (edited) we have it also..pay dearly for it...I am to where I buy it for the small engines about the house..chainsaws/weedeater...next time I fuel up my 54 will probably put PURE that in that tank.

Dodgeb4ya Posted June 19, 2014 Report Posted June 19, 2014 I've seen the green tinge old varnish gas too. Quote
JDaniel64 Posted June 19, 2014 Report Posted June 19, 2014 Quite possibly the green is caused by corroding brass and/or copper parts in the fuel system, fuel is probably really cloudy too due to moisture as well. 1 Quote
jhm1mc13 Posted June 19, 2014 Report Posted June 19, 2014 Rodney, I suggest cleaning out all old gas and go to non ethanol which may be found at marinas. The boat people are having a fit with this ethanol. Be prepared to pay premium prices. Jim Magennis SC Quote
Don Coatney Posted June 19, 2014 Report Posted June 19, 2014 I use ethanol enriched gasoline in all of my applications not because I like it but because I am a tight wad. My P-15 has set idle for several months. I have never added any snake oil stabilizer. I have not yet had any issues with stale gas or failure to run. I installed a fuel filter between the tank and pump strapped to the frame under the drivers seat. I have never serviced this filter in 10 years. Why is Rodney having this problem and I am not? Makes me wonder if the problem Rodney has is not ethanol related???? Quote
desoto1939 Posted June 19, 2014 Report Posted June 19, 2014 Hey Rich, who is this "they"? Hey Greg, WHen I said THEY I am refer to the Government. State and also Fed. If they can get rid of our old cars then they chnage the fuel to run on various amount of ethinol. We are just pawn in the game. These old cars do not make any money for the gov't since they have already been taxed. The state of Pa only get the one time reg so we are a non revenuse creation to them fee and there is no inspection required. Hartung Desoto1939@aol.com Quote
