So these boost bottles... how do they affect the air fuel mixture once installed... do they lean it out or richen it? Also, does a boost bottle work on a similar premise as a reed valve... in the sense that it is trying to manage some backflip from the carburetor? I know a reed valve only lets air/fuel mix into the engine and prevents any blowback into the but does the boost bottle just take that blowback up into it and then reuse it on the next stroke or something? I am looking to make my own boost bottle considering they are very simple designs and was also wondering what the dimensions need to be for it... I’ve seen people make them out of many things so just looking for some advice as to size... and what size tubing and brass fittings are used? Thanks!
