HI Mike and Phil

I have completed all tests again as per your suggestions. I found that the compression reading on number four cylinder still showed a reading of 75 lb and did not change after adding 5 ml of oil for the wet test. Mike. I also removed the mudguard and as you suggested and it certainly makes it easier too work on.

I recruited my wife Jo to assist with the cranking job and was pleasantly surprised when she accepted as she has not really shown much interest in the restoration project, her standard comment was, "Boy's and their toy's" I am sure she was surprised that I actually completed the restoration.

Cheers

5ml of oil isn't much.. maybe not enough !

If the tappets on that weak cylinder are OK, then you probably have a leaky valve .

Try Phils idea , use an old spark plug and braze a compressor fitting on to it ...or a tight fitting clamp might do.

After you pump the air into the cyl. put your ear next to the exhaust outlet and listen for a hissing sound . Then go to the carby and listen.


Or just go for it pull the head off !

Thanks mate, I will do the wet test again with more oil and have a look at the other suggestions as well.
