Done with bad fuel !

[sean donato]

Yeah I hear that. I normally run any float-bowl carburetor dry when I'm done using it, especially my '74 RD350. Can't reach the carb drains on that unless you loosen the clamps and twist the carbs in the manifold sideways. A huge PITA to do every single ride. I've found just shutting the fuel off at a predetermined spot from my house, then riding the last 1,000 feet on full choke works well.

As far as diaphragm carbs, I've found leaving them full of fuel results in far less issues. Don't really understand why that is. Maybe since the crap in the gas holds the diaphragm open allowing internal leakage. Not really sure. Whether it's a chainsaw, weedwhacker, leaf blower, or the giant diaphragm carb (Walbro WB-37C) on my paramotor, they will ALL not start the following year if left 100% dry after running E10.

The paramotor sat all fall and winter (After I broke my hand) with E0 & Saber, and fired right up 6 months later. A little extended crank time, but not too bad. The saw sits a year at a time or longer, and always fires up relatively quick on E0. It used to take way too many pulls on E10, usually requiring a sniff of acetone to light off.View attachment 1008683View attachment 1008684

The ethonal dries out the diaphragm and fuel pump membrane. Walbro actually has released aa spiral diaphragm to help combat this in the smaller wt series carbs, and also offers a ethonal resistant purge bulb. (Silver black in color)
my father in law paramotors as well and has taken a liking to running canned fuel through his motor and fogging it before long term storage. He seems to have little to no issues with his fuel system each spring. It's a neat hobby, but expensive.

The trufuel isn't the same chemical make up as pump gas and is much more shelf stable. Just like aspen 2t or most any other fuel in a can.

Right, entirely different stuff. Like avgas, without the lead.

How so? I know they get gas before they add EPA garbage to it…is there something else?

Look up alkylate fuel.

 

[HansFranz]

There are actually many products out there that do the same thing.

Can you name/recommend any? E-Zorb is expensive.

There are actually many products out there that do the same thing. One of the issues with using it is it still takes power out of the combustion process to turn the water into steam, but it will get you by in a pinch. Back when I was still a heavy duty diesel road tech we found stand by generators had lots of condensation issues with their fuel tanks. Tanks would only get refilled at 1/2 full level. This actually takes quite a long time of they aren't powering the store or hospital for any amount of time. The hour long exercise every month doesn't use much fuel. We found that a water absorbing sock coupled with water blocking pre-filters eliminated most of that issue. Also started treating the fuel with an biocide. Worked well for the gens that only got attention once a year and didn't run much.

I use Zinga filters with their aquazorb media on my diesel storage tanks. The filter media absorbs water to the point of stopping the flow of fuel. I've seen it in action with a contaminated batch of fuel it stopped a 25gpm pump in its tracks. Zinga used to have a disclaimer that if using on an peice of equipment that could create a hazard by shutting the fuel system down from a plugged filter to install a remote service gauge and a bypass with an alarm so that the operator could choose to continue to run the engine to a safe stopping point, otherwise once that filter plugs off its shut down with no notice.

It's an alkylate based fuel. Much more stable then the typical "pump gas"

I can't follow what the op is saying....

I am not sure anyone can.

 

[Bill G]

You hear suddenly about lots of fuel problems because people are talking EV these days. Wait uintil you hear about all the battery and charger problems that are poised and ready to erupt. Just MHO.

You say erupt I agree and will add BURN

 

[Bill G]

Ethanol baby. The devil is in the blend, to be sure.

Just do not buy it then if you do not like it. No one is forcing you to. This America and we have choices..

 

[Bill G]

Maybe the fuel starts to improve again after 8 or 9 years sitting in the saw...? Like fine wine or cognac...?

Dunno

Well women do so why not gas

 

[Bill G]

Perhaps he was huffin bad fuel and that’s what this is all about…lol

Well if it was ethanol fuel he could get a double whammy

They force me too here thats all there is available.

Super helpful fella you are!

We used a product called k-100g in gas applications. There are many other products similar in nature to it. I won't lie, a Google search will yield more information on suitable products as I was mainly a diesel guy. The biggest gasoline powered gensets I got to work on were pretty little by comparison.

The water aborbing socks we used in diesel tanks were from b3c.
https://b3cfuel.com/product/diesel-tank-snake-storage-water-absorber/We used the black socks, but they make a yellow version as well that was a use and toss variety. They make a few additives as well, but nothing that wad cost effective when treating hundreds or thousands of gallons of diesel. Typically it was cheaper to use a fuel polishing system to clean the tank. Add the snake and a water blocking pre-filter and keep after it then run the risk a generator wouldn't run from contaminated fuel. I did take care of a lot of grocery store. Hospital and health care facility generators. So it was critical for them to run. I don't know if they offer something for gasoline, but they made an excellent product for diesel that wasn't alcohol based.

Well with all due respect I am betting if you are in a rural area you have an airport near by so you will not find ethanol fuel there. I do not know what the pine barrens are but trusty wikiliars says New Jersey. I know nothing about New Jersey other than I thought your former governor was a hoot and should have been president. That is irrelevant though we are talking gas. I have heard Jersey has some odd laws so I am not doubting that you are having trouble finding non ethanol fuel. I do believe if you do not have an airport near by I am betting you have a local race (circle) track. There will be a fuel truck at every race and they sure as hell do not sell ethanol based fuel. Here we have race fuel pumps at gas stations but there is always a fuel guy at every track . Another option is hitting a tractor show there will be plenty of fine folks that will direct you to where to find it.

In no way am I trying to be an ass I am just saying it is out there but I have no doubt if you are in Jersey it is tough to get.

Never heard of them. We typically used davco, racor, or fleeguard filters. I use golden rod on my personal transfer system. The fuel polishing system we used has special filters that would block water. They were about as big as a 5 gallon bucket. Watched a gauge for restriction then you would have to drain the water out of them. I'll look up that brand you mention.

Well generally common sense is helpful. Why complain about something...Do something about it

Did you see me complaining? OP mentioned problems, I cited a probable source. I don't buy ethanol fuel for any of my small engines.
Move along Shrek.

I also use Fleetgaurd, Racor, or Donaldson in my equipment whenever possible.
The zinga filter I mentioned is only used on my storage tanks for their total water stopping ability. I'm sure there are other options, this is just one I'm aware of that works well.
