Next problem>>>> Cleaning the carburetor I took the plastic part out that is below the throttle stop screw. I think it may be called the pilot tube. It has a small o-ring at the bottom. I think it may be called the pilot tube. In the video it shows cleaning out the small hole from the end the o-ring is on. It looks to me like there is a tiny hole in there but I have tried to push a tiny wire .0185" through but it will not go. The carburetor was pretty clean. No sign of varnish etc. I wonder if my carburetor is not supposed to have a hole there??
