I think I've traced my carbs troubles back to the gas tank, I think it's rusting out, and rust is clogging the carbs.
When I pulled the carbs off to check them both needles and seat where stuck closed, there was a a few particles of brown 'stuff' in the bottom of the bowls, the fuel filter also had 'stuff' in it. So i used the fuel pump to fill a clear plastic bottle (500ml) of gas, let it sit for a while and there is a ever so slight amount of 'stuff' at the bottom, which was so fine as to get past the fuel filter.
Now a new tank is over $400 CDN, I not going to mess about with the old one, so it looks like I got to dip into the 'old saving again, guess those new golf clubs will have to wait!
MG gas tanks are known to rust out. Two approaches are availiable, treat your old tank with POR15 gas tank cleaner/sealer, or buy a new tank. I used a floor jack with a piece of plywood between the tank and the lift pad to remove and reinstall the new tank. This way, it was a one man job. If keeping the old tank, be sure to get a new mounting kit and sending unit, you'll need the new filter end on the pick up tube.
Got the tank out, first thing I saw was a 4 x 6 inch hole, on the top of the tank with about a dozen smaller holes around it, already got a new tank on order, along with a fitting kit, sending unit, filter and lines, should be here Monday afternoon.
Now how do you dispose of the old tank and 25 Liters of contaminated gas?
You can save and use most of the gas. Let the tank sit long enough for the rust to settle to the bottom and siphon the gas out without letting the siphon hose reach the bottom of the tank. The tank will need t be on a table or stand of some sort to do that. Or you can pour the good gas out if you don't agitate the tank or try to pour every bit of it out. Dispose of the small amount of contanimated stuff as you see fit.
You ain't so much of a tree hugger after all. He could also use it to get his old tires started burning so he doesn't have to pay a recycle fee. Here in the states that's called sending the EPA a smoke signal. You can roast wienies over a burning tire much faster than you can microwave them. Marshmellows simply vanish before your eyes and all you get back is a blackened stick that tastes as bad as the wienies. Even Tobasco and Grey Pupon can't improve the taste.
Well, thank you very much! I was wondering where that chain sound was coming from!
I mix my used gas with old motor oil and send it to the recycling place after agitation. It's free. Or, use it for brush fires. No tires though.
The gas tanks are now made by a gas tank manufacture in Quebec, who bought out the company that used to make them. I've been told by my supplier in Montreal, Christian Hollum, that you should be able to buy the tanks through your local UAP store. Unfortunately I had bought my a few months earlier for $400.
I would like to think it was me, but you probably didn't know I work for the EPA! Believe it or not, we (at EPA) like to think we are reasonable, and know that there are two sides to every argument. How else do you explain why EPA is sued as often by environmental groups as by industrial entities. Evaporation is actually a remedy for volatile organic contamination such as petroleum products (i.e. gasoline). Recycling used tires helps them get used for other beneficial projects, such as stream stabilization, or at least avoids out of control fires. I took my old gas tank to the dump, where they accepted it as hazardous waste but didn't charge me anything. They also accept used gas and oil, from where it will go to be recycled into materials such as bunker fuel or dust suppressant.
I didn't mention my employer to spur a debate on policy, and please don't anyone think I read this BBS and am critical of anyone's practices. We all make our choices. I keep my B smogged because California wants me to; it passed tests with flying colors without the air pump, when Idaho let me get away with it.
At least for me, I think owning the 74B is an environmentally sound choice. It keeps at least one non-recylable Miata/Z3 off the road!
