Is that the whole thing?. In your first picture, post # 116 it almost looks like something is missing up front. I was going to guess it was a motorized trailer mover, but there is no ball on it. So now that I've at least guessed, put and end to this unbearable suspense and tell us what it is.
Or just a new needle and seat, OR a new carburetor for those who are not road-worthy. Many times a brand-spanking-new Chinesium carburetor is worse than the old carb. Even after a new needle/seat, I still use the fuel cutoff valve religiously.
I’m not talking to you directly, I’m talking to the peanut gallery.
It was 71 degrees out, so I took advantage of the weather.
I used some locally sourced sand and gave the frame a once-over.
It did a good job of removing the stuff that was loose. Some of the paint was still pretty adhered, so I just let it do what it wanted.
My hose was set to max 120 psi. I noticed the sand blew better at 1/4 throttle. I turned the regulator down to 50 psi, and it worked better.
