No the studs are not long enough for both, and flats will suffice.
Just be diligent and nip them, the manifold nuts, and the carby screws
up every so often.


Cheers, Mick.

Hello All,

I picked up an air cleaner unit off a HQ 202 from a wreckers for $10. However, it did not have the air cleaner filter clip - the part that the hose from the tappet cover joins on to. This cost as a genuine part $64 Oh well betwixt them both I should be on track to getting things sorted out.

Kind Regards

Hello All,

If the arrowed part in the photograph is the float - is it meant to be able to be moved up and down with the air horn off?

The float is ceased and I cannot move it with my fingers neither up or down. I would think that the word "float" lends itself to the fact that the device actually moves - hmmm up or down depending upon the level of the stuff it "floats" in - for example, mmmm petrol.

Kind Regards

Um yes.

As the float bowl (that word again) fills with petrol, the 'float' floats on top of it and the little tag on the side of the pivot opposite the float, presses down on a needle. Once the float is high enough ie, there's enough petrol in the float bowl, the needle is pressed into the jet, closing it off so more petrol can't get in.

So yes.
Your 'float' needs to float and it needs to pivot freely around the shaft.

Hello Crackers,

Thanks for confirming that the float is meant to move.


Is the float being totally stuck something beyond a bit of detritus floating around in the system?

If it is beyond a bit of gunk lodging in the wrong place then it is so much for the carburettor being "fully re-manufactured, bench tested and ran hot so that it does not need any adjustment". Is it RonP38 who has the thread about having the knack for buying defective products?

What is the best way of freeing up the float so that it can indeed do what it is meant to as in move and float.

Kind Regards
Lionel

Your tiny pictures don't blow up very well but I think I can see a metal tab just above the needle and seat that is holding the float down. There should be a metal splash guard in there somewhere, I suspect its been installed incorrectly. You'll need to extract the tab with a pair of pliers and work out if it fits in there without jamming the float.

It could be some gunk so squirt it out with some sort of cleaner. It could also be a bent tab as bee utey suggests. Just have a close look and it'll become clear. I don't know those specific carbies but the floats are usually easy enough to get out - you need to be able to to change the needle and jet. Just don't drop anything is six inches of wood shavings under your bench
