Thanks for the advise guys......
I have no valve tap - it does have solids on the cam . I have good lift on the valve train - i did a compression test a while back and saw the compression gauge show some leakage after i first turned it over to get a reading. I then cycled it again and this time it hold for quite a while then leaked down slowly. I will need to do the sound check as recommeded to hear where the leak is - cyl, carb or exhaust??
Assume no other way to do this??
