Catastrophe!!! Petrol in oil?

If the tank is low, you could drain it, although if it's half a tank or more, you will need a lot of cans...

The carbs look like ICT 's.. the needle valve is in the top half of the carb body, so you have to take the top of the carbs off.

 

Where the pipe is with the jubilee, follow it to a tee. Clamp it on the feed side of the tee, get a garage to it .

 

@Merlin Cat before you do anything, tap the top of the float chambers with the handle of a screwdriver the floats valves are probably stuck

 

Replacing the needle valves on ICTs is easy. You will need paper gaskets for the tops and needle valves. They are sized so you will need to know what size they are. That is stamped on the valves. They are removed with a 10mm socket. Everything can be bought from Eurocarb. It can be that they are not worn but a bit of dirt is stopping one of the needles closing. It only takes a bit. You only need a screwdriver to take the tops off.

 

I can email you the ICT section from the Weber Tech book if you want it, just pm me your email address.

The needle valves are part 6 on the diagram. Honestly, it is easy to fix if you need to replace the needle valves.

 

This is great advice. If it has been stood it only takes a tap to loosen them sometimes.

 

Do you not no it’s us plumber that make leaks so we can earn more money lol

 

You seem to have same carbs as me Weber ICT 34's. I had a similar problem about a year after they were installed, it seems that the float wasn't floating, it had sunk! This meant that the fuel was leaking into the engine through the carb as the float was't doing it's job. I imagine the plumbing analogy is a ballcock not sealing the valve.
Eurocarb admitted that they had received a number of complaints and that it seems that there had been a faulty batch of floats. They replaced mine for free as it was just within the 12 months.

 

No need to take filters off but it makes it easier if you do, this happens all the time it is a common problem

 

Thank you
My skincare, haircare and beauty regime is certainly paying off these days.

 

Still think you should send it to me.

 

As it's a 70s Landmark, you could loosen the float valves by playing "Stayin' Alive" very loudly next to the carbs

 

Is it parked on a slope

 

That’s good then , is yafuel pipe clamped up nar .
