I've got the stock air cleaner for my carb. It's a Hitachi carb off of an L20b but it's on my L16 powered 510. Anyway, there seems to be something missing from the neck of my air cleaner and it doesn't fit the neck of my carb. I can just set it on the carb but it rattles and I assume it lets quite a bit of unfiltered air slip by.
I went to Autozone and Checker to see if there were any aftermarket setups I could use. I ended up buying a filter assembly, then had to spend more money on the 3 1/16" adapter, then more on the bolts, and none of it fit. The neck on the carb seems to be around 3" but it still wouldnt fit over. They also have some 3" flexible pipe that I could attach to the carb then run to a cone filter but I dont want to risk it not fitting over the carb neck. The only idea friends/family could come up with was dryer tubing clamped over the neck then run to a cone filter and clamped. The same as the flex pipe but a bit more ratsun in style I suppose :P Downside to that is it looks a bit...yeah, and also it's 3" exactly and I dont think would fit over the 3" carb.
Anyone have some ideas?
