Thank you. Let's try a valve adjustment first.and then let me know if you still have problems, but this fixes it in the majority of cases.Intake - .003"/.005"Exhaust - .005"/.007"The setting should be done on a cold engine with the piston 1/4" past top dead center on the compression stroke.Here's some additional information that shows the process in detail. Scroll down to the bottom of the page to where it talks about adjustments. It will link to some helpful pictures as well. If there's anything you're not clear on, please let me know.Valve InfoHope this is helpful!
