Ok so let me tell you about the circus i just was involved in. Called Bailey's about that jet they sell. They were about as helpful as a square of toilet paper in a rain storm. Couldn't give me any info. other than what was on the website. Then i talked to someone at a walbro distributor in the central us, they were just as helpful as Bailey's. Then I contacted Walbro directly which is probably what i should have done from the start. The tech who helped me had trouble but did eventually find that the .76 fixed jet with part # 112 466 76 1 was indeed used on the HD-24 carburetors. So that jet that Baileys sells should work for any of the fully adjustable walbro carbs used on the 1128 series saws. Not certain about the walbro carbs on the 064's, but it should work. I have other parts i want to order from Bailey's so i'm going to throw that fixed jet in there. Sorry for the wall of text but I hope that provided some clarification.
