Slips. I misread the dial caliper by .100”. No wonder my builds turn out so poor. The smallest fuel tubing that I have is .170” OD and I believe it is the tubing that Stihl uses for the clunk line in a saw. The smallest tubing (not fuel) that I have is .125” OD and it came from an oxygen nosepiece used in the hospital. Fuel tubing that fits over the servo screw is approximately .215” OD and would require a hole of .190” to .200”.
Please accept my apologies.
Where can a guy buy these nylon bolts or screws?
Nylon bolts are available in a variety of sizes below 1/4” from Lowes.
