Hi Pendragon
I found it difficult to feel the compression by placing my thumb on the spark plug hole. So I use a compression tester without the dial gauge but the finger of a rubber glove fastened over the end. As you crank the engine the glove finger inflates. Do it too quickly and it pops like a balloon. If you don’t have a compression tester, sacrifice a spark plug by drilling out the core.
Once you have established TDC on No 1 compression stroke put a dab of paint on the cam pulley immediately by the bolt on the dynamo housing. In that way you will always be able to find TDC on No 1 without resorting to cutting up a rubber glove.
Cheers
