Hate posting this cheesy video again but I really need help. In the video right when the red stripe (at the bottom of the video) gets to the line between the gear looking thing (quality icon) and the clock looking thing (watch later icon) until the end you can hear what I'm trying to fix, a slight popping sound. I've set the valves to cam specs twice and checked three different times after running, each time all is good.
My thoughts are carb adjustments but I'm just not sure what carb adjustment (if any) would cause that annoying popping.
The accelerator pumps levers/arms have no gap/clearance. I have always thought they were supposed to have .015" clearance at WTO throttle but they are tight to the diaphragm at idle position.
Would a vacuum leak cause popping at idle?
I have Autolite 24 plugs in the motor, would a hotter plug be better? Would NGK 8 be a better choice ?
Would appreciate thoughts and info, Thanks guys
