It all depends if she's been kept with a full tank of fuel or not. It might explain why she plays up with a full tank - slight corrosion on the upper surfaces which gets dislodged when full.

A small gas lighter refill cannister is really handy for blowing through jets.

I had similar issues with a 1986 4 seater which had a mechanical fuel pump. I had already checked it was pumping fuel ok by turning the engine over with the fuel line in a jar. Eventually, a friend who was a professional mechanic told me that mechanical fuel pumps can work intermittently when they are on the way out rather than packing up altogether. The flap valves jam or leak. I changed the fuel pump, problem sorted!

It had a new fuel pump fitted by AW in June last year - however, I have had problems with mechanical fuel pumps in my Land Rovers caused by wear on the camshaft. Had to resort to electrical in the end.

SUCCESS!

Finally, all the ducks lined up smile

Once I got her started this morning (took a while, but she had been sat for three weeks) and idled OK. Half way to breakfast she started playing up again and still playing up when I got home. Whipped the idle jet out, gave her a spray of carb cleaner and she started up perfectly and idled beautifully!

Thanks for all the help and advice, it's been much appreciated. Hopefully in time, all the rubbish in the tank will work its way through, and in the meantime, I can fix it in minutes. smile smile

That is great news. Sounds like the long term fix is to put lots of miles on her. Win Win.

That surely depends upon what the rubbish in the tank is. If it's rust unless you seal the tank the problem's going to keep recurring.
