I have been forced to change the low-compression head on my 33 tourer, due to corroded water inlet bolt/stud. I have now fitted a high compression head (in very good order) and new gasket to suit. Torqued down to 20ft/lbs (cold), but compression seems to have dropped considerably, and it won’t start (always been a good starter). Any ideas anyone? Thanks.
