The Moron Mechanic also mis installed the front cam chain adjuster. See the upside down U on the left with the groves in it ? The bottom of the chain adjuster should set in that grove and hold the chain inward. If the bottom is carelessly stuck in front of its slot it will cost the next owner a year of futile timing adjustments and carb rebuilds being clueless until a major tear down exposes the problem. This moron cost me more hours that I want to think about.
