I was able to run my motor today. The sun was in a perfect position to see right down the throat.
I am full aware of which is which in regards to High and Low speed jet adjustment devices. I looked down the throat and I could see gas emitting right out of the high speed jet (The one in the front). I decided to close the low speed just needle. I was able to close it completely and the motor still ran, and no change in the amount of gas emitting from the high speed jet.
I am going to take the jet out of the Carb tomorrow and see what shape it’s in. I still had a needle from the original Carb that was on this engine and tried it. Same results. The old Carb was totally corroded and actually breaking apart so I changed it. I was not able to get the actual jet out and I no longer have the Carb 🙁
Attached is a pic of the Starting and Operating Instructions that are on a decal on the tank. Zoom in and look at number 4. It states the Low Speed Needle is 1 1/2 turns. You have to notice there is a 1 between the 4 and the 5, then a 1/2 which to me says 1 1/2 turns out as a starting point.
I will post back how the High speed jet looks one I have it out.
Thanks everyone!!
