Default Re: 2 stroke engine without an Air Cleaner

I think most of the bogging down always described here is usually because of a rich mix, not fuel starvation , because closing down the petcock seems to help, but more oil in the mix is best.

So to get a little more air, I drilled a few more small holes in the back of my standard plastic air cleaner. I'm not going to run in dirt or bad weather, and it still leaves the foam on the inside to filter out particles, and the outside plastic to stop anything bigger-
the stock openings at the bottom seem a little restricting, don't they?

and it seemed to run better- a small drill bit goes through the plastic like it's nothing, and you have to look closely to even see any difference
