Hey Gram...where are all these little air holes we should hit? I just wanna make sure I get them all when I clean it.
holes in the throat are below and just behind the air valve in the throat. The pilot air hole is the small one at the front of the carb
at bottom, and the needle jet is what the needle slides into when the slide goes up and down.
I have seen some needles that had some buildup too. Not sure why, perhaps the material difference. But I usually touch those up with emory cloth or something similar whenever I take them out for any reason.
If you have your carb apart definitely give all the jets a saturating spray too.
