I started building this engine a number of years ago and kind of got it running the middle of last year. I've messed around with the fuel system some, trying a vapor carburetor, a model airplane carburetor, and a home built carburetor. A couple of weeks ago I decided it was time to buckle down, get it running right and finish it. I rebuilt my home made carburetor, taking a lot of care to shape the venturi and replace my 2-56 tapered needle valve with a largish sewing needle. I built a new base for it, installed proper spark plug wiring and boots and hid the battery and wiring in the base under a small, removable trap door. I added a 90 volt DC motor as a generator powering a 60 watt light bulb and now feel like I've got it running and looking pretty good.
