now... this is going to sound so bluddy improbable......
in 1961 i bought an austin 7, on the face of it not a bad little car, it was a runner, and the lights worked, upholstery was serviceable, and bodywork reasonable.....but.....engine was a bit rough....
you need to understand that i was in the RAF at the time, had just finished my training, impoverished, and in need of wheels (the local women wern't too impressed with my beezer bantam). and motors changed hands, usually for about 50 quid as guys got posted overseas. (thats what i paid for the car, and a couple of years later for a 500cc goldie!)
So, having handed over the 50 quid, i was the proud owner of an austin 7 about 25 years old.
Great stuff! down the local with a car full of lads, 2nd day out the engine got really rough, I thought it was having 4 pi55 'eds on board and hauling up wiltshire hills.....but it expired half a mile from camp, so the blockheads had to get out and push.
following weekend, about 20 blokes all with theories as to what was wrong, the general opinion was no compression on at least one cylinder........like.....take the plugs out.....stick a finger in the hole, turn the engine over......(crank handle at the front!) if your finger squeaked, then there was compression.....
having established a lack of compression.......opinions were divided between a broken/burnt valve and broken rings/piston
being a side valve engine...taking the head off was a ten minute job..................
Oh my gawd...........
number 3 piston had a hole in the middle......the hole was actually in the middle of an alloy plate riveted and araldited onto the piston crown.... used to seal up a hole caused by a dropped valve at some stage in its life.
If you're out there Greg Thompson......you ba5turd......I'll get you!
