V twin Intek engine.
The written directions say to do it how I would do it with both valves at .005.
The video shows a technique I think would work with both valves at .004.
This engine sometimes backfires when customer turns it off. The fuel shut off solenoid clicks when I turn the key. I think these are the engines that have vanishing push rods that I have read about in here.
Why would both sparkplugs be bad? When I got there, he and his dad tried to tell me it had spark. When I tested it, I got shocked by the wire but there was 0 spark where the spark was supposed to be. New plugs and it fired up.
I was thinking water in the gas would do that, age or someone dropped them really well a few times.
Anyway, I want to do a valve adjustment out of caution and hoping it cures the backfire too.
