T: Fuel Tank Temporary fuel tank for carb tuning?

[CoreyL]

Esteemed Ones,

I need to do some carb tuning (swapping throttle slides and changing needle clip positions) on an Amal Mk1 Concentric carb mounted to my post-war single. Removing the top of the carb requires removing the fuel tank. In order to minimize the number of times I need to remove/replace the large fuel tank, I'd like to temporarily mount a small gas tank on the UFM that will let me make changes, road test, repeat...

Does anyone have a specific auxiliary fuel tank they've used and can recommend? Preferably something I can acquire in the US.

Thanks in advance,
Corey

Not really for road testing, Unless you mean just up the path ?.
Cheers Bill.

Thanks, Bill. I have one of those ones that are meant to be hung alongside the bike. I might be able to make it work with appropriate use of zip ties and duct tape, but I was hoping for something more elegant.

I'm hoping to find something like the setup in this video of Matthew Biberman:

I asked Matthew where the fuel cell came from and he wasn't sure - it was something that Big Sid had had for a long time.

I have been looking at some smaller bikes , At auto jumbles, For the same,
But not found one yet.
My next bike I want to test, Has an oil and petrol tank in one ,
So I am stuffed on that !.

Just a thought, Ron and me built a Comet for a friend,
With a standard carb',
And we just took the top off the float chamber , And I stood there, Topping it up !!.
Lots of FUN.
Cheers Bill.

What do you think about an NSU Quickly tank.The small one which sits above the frame? Erik

That is what I made mine from when tuning years ago. Whether there are any left now is the problem.

I think you could adapt a lawnmower or similar garden implement tank.

I thought something like this might work: https://www.ebay.com/itm/172719103983

I would check what threads are used for the fuel taps on these and buy a couple of taps if they have some different standard.

I Used an 5l oil canister, modified the bottom side for fitting a hose and fixed it with cable ties. Not beautiful but worked pretty well with a good Range.
