not quite running properly

[bmcecosse]

Blimey! The little black knob on top - when unscrewed - lifts out a thin rod with the damper piston on the end. That's the damper - while it's out - lift the piston and let it fall!

will do, its closes good justs need help opening so i will give a little polish and try again when i get the new needle

[hotrodder13]

ive had a go at polishin it and with the damper removed it falls about 3/4 way then when shaken it falls the rest. but the when i put the oil in there (using dashpot oil) it moved slight then with a slight tap of my finger fell bit more

is this right or is it still wong.

thanks tom

aslo the needle bgw any good for a hif44

[aupickup]

it sshould drop down on its own accord

[hotrodder13]

well i put it on the car and found out the screw on the back of the filter was pushing the dash pot over and it wasnt moving properly so i sanded the dash pot and took it for a test drive, its stilll seems to jerk a bit but no were near as much, and it started to die at speeds so i think i need to wait for my new needle

[bmcecosse]

It MUST rise and fall easily and smoothly........ BGW needle doesn't show in my records.

Filing or grinding the offending bolt would be better than sanding the dash pot.
Have any of the three "ears" that hold the dash pot on got distorted?

I see no mention of the spring that acts on the damper, I trust there is one fitted.

[hotrodder13]

well without the spring it moves freely with the spring it dosnt could it be the wrong spring

[MarkyB]

A picture would help, they are supposed to be colour coded but I've never seen any kind of colour on one.
Very interesting that it works OK without the spring though.

[hotrodder13]

what would you like a pik of

[MarkyB]

The spring!

Pictures of the damper and the inside of the dash pot wouldn't hurt while you are at it.

[bmcecosse]

Don't understand it not working with spring - obviously it will be a bit more difficult to lift WITH a spring than without - but the dropping/closing should be even better!

[hotrodder13]

dropping is better just dosnt move up properly ill have to get a pik later

[hotrodder13]

found a needlewith adg does this sound better then mine for the time being thanks tom

[bmcecosse]

No - just as useless.[frame][/frame]

But you could try the complete carb......

[linearaudio]

Lets stop beating around the bush!

If a fixing screw on your super noisy air filter has been bearing on the dashpot enough to inhibit the free movement of the piston, then all talk of needles is a bit academic!

Get another dashpot or complete good carb and start from there, using an AAA (I used an ADK which isn't far out, and available from Burlen).

[hotrodder13]

well it not pushing it now i do have a bigger carb i got cheap but not got the stuff to fit yet so i need a quick fix for friday

[bmcecosse]

Fit the spare carb! Surely the AAA needle should be with you by now ?

[hotrodder13]

cant fit the spare carb as its siezed, and no needle as they only posted it 2day i might be lucky and get it on thursday

we will see

thanks tom

[bmcecosse]

Unseize the spare carb! Soak the bell/piston assembly (I'm assuming that's what's seized?) in boiling water for starters!
