Alternate Gas Tank Options

[anickode]

So once I get the outlet installed, I should solder it in place. Is that what you're saying?

Absolutely. You can't thread a pipe fitting into 28 gauge metal and have it seal. Double up the metal in that spot and solder the pickup in. You can solder a brass bushing instead of a nipple if you prefer. Then you can thread in a nipple or a bowl separator or a shutoff valve.

And to answer the flux question, normal plumbing paste flux will work fine on tinplate.

OK, I'll give the clone tanks a shot, and it that don't work, I'll use the brake fluid canisters.
Main reason I'm trying the clone ones is because they're already made & complete, and they have the capacity advantage.
Also, when I someday do my dream dual carburetors, it'll get a bit more thirsty, so it'll be good to have extra capacity.
Whenever I do the dual carbs, I'll probably just get one of the Chinese 2 piece Flo-Jets. It'll be interesting, since almost everyone does a Mikuni for a performance carb, but adding a second normal carb will still increase the flow significantly, while also making it extremely unique.

Really, regular flux.....Im totally surprised to hear that... I used to solder alot of sheet-metal. All galvanized... nothing else really touched it except acid to etch the galv off...

Cans like this are still tin plated, believe it or not. You're right about galvanizing and zinc plate though, plumbers flux won't do it.

Right..... ya thatll wick no prob.......... nice... I reckon ill have to try a few.....

Problems is.....No more steel cans..... Or very little.



First world problems eh..... Missing Cans....Gees... the apocalypse is going to suck for us....

....Meanwhile the third world carries on.......cracks open his glass botled Coca-Cola with a steel bottle cap... good times...

And they put 'em in a rack and return them to the store for the deposit, where they are then picked up by the Coca-Cola driver, taken back to the bottling plant, washed, refilled, and shipped back out.

I know eh.....

What about a 6 inch metal water pipe with a cap on the ends and a fitting in the middle like where another smaller maybe 2 inch pipe would 't' into it for the filler neck. you could then drill a barb into one of the ends where the end caps are.

That is a VERY good idea!
If I had better access to welding equipment and metal, I'd probably do that!
I would make it out of good 'ol steel.

Also, I know it sounds weird, but I'm actually putting off ordering a gas tank, because I'm using that same money, and I'm going to pick up an 8 HP Briggs flathead this weekend!
For only $30, too....
I know I shouldn't get overexcited, but if what the seller claims is true(good compression, strong spark), it should be a pinch to get it running again!

I just picked up a 5hp industrial for 20 bucks. The crank is bent at the output shaft. I got it so I can give my buddy the tank and carb off it. I wouldn't have thought it would have cranked but I had to try it...so I sprayed some magic into the carb and she fired right up. So after he takes what he needs off it I may find a crank and put a mikuni carb on it and see what it will do.

Sounds heavy as ****.

I made one out of a 2 gallon hot dog air compressor tank... Weld tabs to mount, use the drain valve port for the pickup, then cut around the inlet port with a hole saw and replace it with a filler neck.

I also made a 5 gallon one out of a $19.99 portable air tank from tractor supply.

I found a old round boy scout water canteen with a deteriorated cloth bag/sack holder thingy in a freebie box at a flea market and thought hmmm?...possible make shift gas tank?

Thinkin its about 1/2 gal.

So i chucked in the parts collection tote for a old cart i have if i ever get around too building it.

Idk what the cap is made of so im unsure if it'll even work or not but thats only one of a few possible ideas i have for a tank for it.

If your set on a predator/clone tank alot of mini bikers usually dont use the tank since they dont fit into alot of bikes,and the bikes usually have a tank already.

So im sure someone out there has a tank that they dont want.

A little off topic but why on earth do you want dual carbs for a single cylinder engine? Much less a small one such as your

“Bro this don’t make no sense?!”

Increased flow, and the "exotic cool" factor.
The go-to option nowadays is a Mikuni, but I want something different.
All it really takes is a custom intake manifold and a modified throttle setup.
I know it's more work for myself, but it's all worth it in my mind.

 

[950speed]

Just saying this and it’s my opinion:

This is a dumb idea even guys who raced flatheads and modified the ^*** out of their engines only used one carb, and on top of that you would have to dramatically reduce the Jet size or else there will be too much fuel, either reduce jet size or reduce carb size all together


But then reducing carb size presents you with your same probables once again, there will be more interference with smooth and fast flowing air since there are now two intakes which will slow t back down after he air passes through the carb, It will still be going through the same size hole/waive when the mixture is sucked into the chamber. It’s useless to use a twin carb







My apologies for hijacking your thread

 

[mckutzy]

This was explained a while ago with a twin carb idea thread... and said pretty much what you said...

 

[JTSpeedDemon]

A small engine book I got from the library defines my kind of high speed AFR screw as an "adjustable jet".
And after installing the header, I did no other tuning tweaks other than playing with the mixture screws, and it runs like a dream.
When I do this, I plan to get 2 more stock intake manifolds to modify, and one of the Chinese Flo-Jets, that way, even if it doesn't work, I can revert to stock easily.
And I know a dual carb setup won't be straightforward, but if I can get it to run with twin carbs, or even gain power with them, it'll be very unusual and cool.

Don't try to burst my bubble with this idea, if y'all do, I will have a mod lock this thread.
I know you guys are just trying to be realistic, but seriously, let me experiment without pointing out all the 1,001 Reasons Twin Carbs Could Go Wrong.
I have a plan, let me pursue it.

“Have a mod lock this thread” what next call your mommy? Sorry but truth hurts we are telling you what will happen, and in no way can we prevent you from doing it but this is a public space and if would like to say how your idea will not help your end goal we can with no issues. Grow up, live kid

We can’t prevent you from doing anything after all it is just words your reading for advice right? Forums are for advice, and giving opinions? Correct me if I am wrong? But I’m not so no need, all we will say is why it won’t work.

Ok, kickstarting this thread, minus that^^ kinda stuff. Cool?
Let's just start over on this thing.
Fast forward about a month, I'm looking at this vintage Clinton tank:https://www.ebay.com/itm/VINTAGE-CL...301123?hash=item3410cf0143:g:SgwAAOSwxgZdUHD5
It's less than 1/3 of a gallon, more like 0.3 of a gallon, and I just want to make sure it'll be enough capacity for a moderately modded flathead(eventually probably a 94SS Cheater cam, maybe some head work) to rip around the neighborhood and some occasional racing.
The mounting straps will make fabbing a bracket easier, the vintage look will match the kart well, and it's just the shape I've been looking for, but I just want to make sure it won't be too tiny for my application.
Thoughts?

 

[anickode]

That'll be plenty of gas.
