Great. You have made some improvements. You need to adjust the HS needle at full throttle.
Not at less than 1/2 throttle where the video is showing the motor running. Your carb needle’s
tip should be up pretty far above the cap. I don’t know the dimension off the top of my head but
if your’s is only an 1/8″ to 1/4″ of an inch or so then that is not correct. The bowl is not full.
Now get rid of that fuel line abortion that you have. Use 1 piece copper or aluminum tubing
with the correct fittings. If you like rubber fuel line with an inline filter then you need different fittings.
Don’t mix them. A fuel filter is a good idea but not the way you have it now. You don’t need two.
Did you clean the fuel tank? Did you look for the tiny filter in the tank? Is it in good working condition?
Yes there are clips on the carb bowl needle. I use cork floats sealed with the Aero Gloss Dope. The sierra
plastic float is great if you set it up properly. Did you? How is your needle attached to the float?
Do not run your fuel line with “uphill” bends. It won’t work properly when you are low on fuel. Here is a
picture of fittings for the fuel line or fuel tank.
