The Classic Marque

Just to echo this. Mine wasn't working either. Luckily for me one of my good friends is an electrical engineer and knows a thing or two about electronics.
We used the above diagram and tested the whole circuit and replaced a few caps and the thermistor that had come loose.

All tested and working fine for a good few years now.

Better to fix the original.

Good luck

I'm with you, Guy - the packing on the buffers was my idea! But when I went to look, I realised that the bonnet isn't reinforced where it lands on them.

I will arrange something persuasive but gentle (pious hope).

That thread made me think - when I drained the oil, I had a massive gasoline smell for a day or so. Like a carb overflow which I experienced once when I raised the back too high to take out the rear axle.
Did maybe the float valve get loose and sucked into the engine ?? Is that at all possible ?? On the other hand, the fuel pump does slow down and stop ticking after the usual number of clicks....

Nick, I only meant that I would put the bonnet on some sort of trestle or workmate that supported it where those wheel arch buffers normally rest. And then leave it to rest like that for a couple of days and see if that eased it out a bit.

I don't fancy packing on the buffers, because I don't believe they're structural - more for damping the bonnet roughly midway between the fixings.
But I might try piles of coats on the inner wheel arches, to spread the bearing loads.

Probably (hopefully an exaggeration.

But why are we even taking the risk?

Yeah, sure, money talks. But you won't hear it if AI d...

I think what is happening is that the cup has nowhere to sqoosh to when it goes in the bore--That piston has 3 sections that look close to bore diameter---one on each end and one up against the cup---I'd think that if that centre one against the cup was to be machined down to the diameter of the main centre piece of the piston ,then the cup lip would have somewhere to compress to when it's fitted ...

Dave, agree it would shorten if stored horizontally, but Nick's was standing up on end I think.
Maybe to shorten again it needs to be supported above the wheel arches, where it would normally close onto the inner wing top buffers.

In that case, you are getting 50mpg in imperial measurements.

yes when driving 50 mph
