Yammie Brap 180

You can put a grocery bag near the intake to make sure you have good vacuum. The carb should try to suck it in. The filter shouldn't affect vacuum all but a leak past or in the carb anywhere can. It can also be a thing if your valve timing is off by a good bit. Ask me how I know lol.

edit: TIL 2 strokes don't have valves so forget that part.

Good tip. I've heard things like covering it with your hand too. However, when I started it on fluid it was just the airbox so I don't think it's a vacuum issue. 

Also, TIL there is a needle jet (#2) which the main jet feeds into and it is removable on these carbs.. Something I haven't removed and cleaned... Seems to be small number of things working against me. No wonder people want to burn down carburetor bikes/cars and collect the insurance money, because, ya know, fuel leaking onto a hot engine can cause a fire.. just sayin..
