Let us know how you get on. 👍

I bought a kit from Repco last year , almost had a hart attack when he told me the price. It was more than $30 & am thinking about $60 for the kit. I almost didn't buy it but I was doing a favour for a friend who has developed Dementia & was trying to get his S2 running so the family could sell it.

Lionel if your putting a kit through the carby it is also advisable to hone the top cover on a piece emery or wet n dry paper sitting on a piece of glass. The tops are prone to warping and allowing air to be suck in, you wont get it running perfect if the top is warped. Honing them is easy and takes only a few minutes to do.

Secondly you can run an engine at idle with top removed from a Stromy to check the fuel level and make sure the needle and seat are not leaking, you just need a small tab of cardboard to place over the air venturi to make it run even. But don't rev the ring out of the engine whilst doing this or you might get fuel spillage onto the manifold.

With a kit through them and in good tune, which is easy to do, they are a trouble free carby.

Hello All,

In the cool light of morning the engine started first press of the starter button. I stopped the motor once the petrol started flowing out of the bottom of the carburettor. After taking the top off I found the float chamber full and overflowing with the float up as high as possible. As A Kelly and others suggested the fuel is leaking over the accelerator pump linkage.

I put everything back together and waited about ten minutes. The engine started again after the first press of the starter button. If the engine stalls and the button is pressed immediately it will not start. Wait until sufficient fuel has leaked out of the carburettor and the engine starts first push of the button. So it is the float levels and related fuel level adjustments.

When I first started with Land Rovers with Holden motors I tried to head off a problem with carburettors by getting a mechanic to fully re-kit the carburettor that came fitted on the vehicle. The first thing the carburettor did when it was returned to the motor was to leak fuel out the bottom.

Later when I learnt how to read the codes I identified that it was a 149 carburettor fitted to the 202 motor.

Looks like a rebuild kit is in order.

Kind regards
Lionel

Try cleaning the needle and seat you have the same problem I had with float chamber overflowing
I didn’t change float level as all was good after crud was removed ,if you Carefully remove brass union that fuel pipe nipple screws into from carbie body inside is a three cornered needle pushed in and out by a tab on the float.
Looks a bit like a button from float side when in carbie
took about three seconds to blow out union on my bench and all was good......could save you the cost of a kit, and resetting float level

Cheers Paul

Try bending the float tab down a smidgen, that may solve the issue. At lease enough that fuel isn't dripping onto the exhaust while you get a rebuild kit.

Guess what...... started my engine to get it up to running temperature and the carbie started overflowing again[bigsad]
So I pulled top off and the float chamber and it was brimming with fuel, pulled the fuel pipe union off and another piece dirt stopping needle seating, I replaced all the fuel pipe before the filter and used an old short piece after the filter when I replumbed the fuel lines. This must be the cause of my problem

Cheers Paul
