Buggered

This is what was found after a friends Reliant Pig came in for a tune up complaining of not running nice enough even after having the RAC out to inspect the car telling him it was the SU carb that was at fault.
We opened the rocker cover to find a siezed valve broken spring and cap, looking further we found that the exhaust valve seat had fallen out wrecking the whole engine.
A replacement s/h 850 engine is going in tomorrow, good runner too as we had it fired up in the back of my transit van today.
