Yesterday I went to my LHS and bought some tubing($11 total) to make an "air intake carburetor". I started with a 1/16" hole which was too small so I moved to a bit that was slightly wider. Now with the hole wide open, it idles(choppy of course). I think this method is going to work. I just need time to perfect it, get the hole size correct, etc.

Scaliwag, you are so right about castor gumming and it may not take as long as one might expect for it to congeal and block the tiny fuel passages in our small engines, especially the TD 010, (my personal favorite).

But a question: How/where do you apply it?

On larger engines I squirt some oil into the intake and flip it over a few times primarily to prevent rust on the ball bearings. But that wouldn’t seem to flush/preserve the fuel orifices on our small Cox engines?
