I am looking for some ideas to convert small diesel CL/FF engines to R/C. I've got an Enya .09 carb I was hoping to use on a small A&E I acquired. The Enya carb has a shank size of 7mm. I need about 6.4mm. (I can still probably use the carb in another engine.) I've also got an OS carb that weighs a little less, but it has a bigger shank. I don't have much in the way of machining tools. I'm just looking for resources/ideas for getting tiny carburetors that can be used on sub 1.5cc diesels. Thanks, Scotty
