Excluding safety, putting 3 or 4 psi of air pressure into the tank will encourage the fuel to head for the float bowl. it might help establish where the problem lies. wear goggles and overalls incase the tank doesn't like the idea...Originally Posted by TZ350

TZ, why not use a Bigger Suitcase?

That will only slow the problem down. The level will still always lower if the float needle cant let enough past to keep up with horrific consumption.
Don't you look at my accountant.
He's the only one I've got.

You need an Amal GP with dual float bowls. Of all the problems possible, running out of fuel in the carb wont be one of them
it's not a bad thing till you throw a KLR into the mix.

If you do go with those nuts from the boltholder you'll need to check the nut seat is true to the thread as every nut bolt and stud i've used from them in recent years has been miles out - aircraft quality is what's needed...

TeeZee , the only reason the base nuts loosen off is due to gasket crush , created by detonation shock.
Maybe not enough to eat a piston but certainly enough to eventually kill bearing cages.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

Do a flow test with the bowl off but with something limiting the drop of the float. This way you can check the flow of the system from the tap to the bowl. There is a guide on how much fuel you need to flow per minute per hp for petrol. I found with the bowl off it could flow enough but bowl on, the needle could not fully open

Yes Fly I agree , I had to lift the fluel level very high in the bowl , so the the floats would drop alot , pulling the needle well of the seat before bottoming on the floor.
TeeZee I do have a brand new Dellorto 4.2 Methanol float valve assembly you can have - the 55 Hp 125MX TM multi Championship 1 plate winner ,needed a 4.5 so yours should be fine with a 4.2.
I also have a screw adjustable powerjet that worked perfectly when its flow was equal to 25% of the main when set to 1/4 turns , and easy to access by hand on the fly to keep a consistent egt
with small adjustments in and out compensating for the changing weather RAD.

This was due to downdraft angle. mk2 concentric's with matchbox gp floats for the quantal Norton Cosworth twin prior to it being converted to fuel injection
Surtess was the manager or something so i guess he had used or offered what he had or was familiar with.
it also used a couple of 60's F1 Ferrari radiators or oil coolers it miht have been Ferrari oil collers as radiators
Grumph will remember

Cam profiles were originally lifted straight from the Cosworth DVA engine, with valve lifts and durations being equal, exhaust and intake, and set at 102 degrees maximum lift both. Maximum valve lifts were 10.4 mm, and at 1mm lift, durations were 274 degrees. Later Gary Flood changed these settings to give intake full lift at 98 degrees ATDC, but despite this early opening, no problem was ever found with valve to piston clearance. Later the intake cam was changed to one developed by John Judd when working with the Williams F1 team, which gave 1.5mm more peak lift.
Squish was set cold to 0,024 thou. but was found to shrink dynamically to 0.006 thou.
Duration looks to be the same as the CB700sc nighthawk at 1mmThe CB700SC was incredibility
276 deg at 1mm lift 120 lobe center for intake 118 for ex.
they must have put a hot can to make up for the 50cc lost due to US making to protect Harleys.

Blah, floats, needles, jets.
Low personal B.M.E.P.
And of course, cams valves etc etc...Blah, floats, needles, jets.

Aboout the time I started speedway the standard two valve Jawas carb was a DellOrto SS1. The hot setup was two remotely mounted bowls (even bigger than the pic of the Amal GP bowls I posted. I couldn't be bothered withthe continual adjustments so put on a 36 (38?) Mikuni and the thing would even idle.
However none of this is helpful wrt to TZ350s problem

i have two of those ss1's .......
if tz added a su float bowl it would have to be able to flow enough for half or a third of a jag 4.2
You should be able to mount it under the main jet?
bellow is an HS4
Another view austin maxi these are rubber hose jointed and can be mounted anywhere at any angle of carb
Are cone locks like the axel nuts on modern bikes?

Nylon melts, metal doesn't, not at those temperatures anyway, I always used cone locks on the LCR brakes If you want to be extra wanky use JetNuts/Kaynuts, they have a reduced hex size compared to others, expensive though
