NEED TO TALK ABOUT TANGS 😀😀

[Moorey]

One of mine on the 350 looked like that.

Did you flatten it out a bit Chris?

No I just set the float height to it.

Yes, that's what i did. Thanks

Or rather I should say I checked the float height and it was ok with it bent like that so I left it as it was.

Yep, in my case 22mm is 22mm regardless of what shape the tang is in 😀😀😀

I would have thought so the measurement is taken from as soon as the spring loaded end of the needle touches the tang I believe.

From an engineering perspective, a curved tang just does not feel correct, although that is not to say it won’t work.  But if there is a problem, then the curve in the tang, and how it works with the valve could be a contributing factor.  As someone said earlier, the brass parts of the float assembly I believe were stamped and that would produce a flat tang.  However, what is not broken does not need fixed.

This is obviously the main difference between an Engineer and a Nurse. A Nurses favorite saying is     ' Don't try and fix it if it's not broken fully, you will only make it worse' 😀. I'm thinking that as long as the tang is not twisted from one side to the other and the tang is set right to give me 22mm float height.....its doing its job.

I put new carb kits in all four carbs and none of them would seal even when tapping the bowls.  I tuned the petrol tap off added 100ml of 2stroke oil in the tank and started the engine with he tap turned off and run it until he carbs were nearly empty turned the tap back on to fill the carbs keeping a eye on the overflows and run it until hot . Turned it off and it's been fine since. Do you run your carbs empty  when you park it up if your not going to use it for a while Julie.

[Nurse Julie]

Nope, never let carbs empty but then all my bikes get ridden very regularly, ie, every few days.

When my cb500 was in daily use I still found turning the fuel off and keeping it running a few minutes every so often plus a dose of redex was a far easier way to get the carbs to stop leaking periodically than taking carbs off.

[Raymond_Y]

My wife would agree with your comment on engineers.  One final thought, if you gave not already done so, you could swap the float with the curved tang with one of the others and see if the leak follows it as a process of elimination.

[paulbaker1954]

Dunno know about Tangs but I have had no end of overflow issues and I have lost count of how many times the carbs have been off and on.

Twice I have bench tested with fuel only to put them back on bike and one of the sodding things would overflow again.

In the end i replaced with ones from Cruzinimage and things have been OK since then
