I have a valve adjustment method that has worked well for me for over 50 years on everything from daily drivers to all-out racing engines, but it's difficult to explain with a keyboard. Can you make a cross-border phone call without having to take out a second mortgage on your house? I'd be glad to PM my phone number for a quick call if you're interested.
