    I've run into a brick wall in my attempt to get a small Carlisle Finch 1/4 hp engine running. :'(

    Been on the search for a lunkenheimer 1/2 inch carb or an Essex 3/8 carb(which is what I believe was used in 1915) but no luck.

    So Plan B is to make one.
    Does anyone have plans for a model carb? Probably one of the larger sizes (for a model) since this little Carlisle has a relatively large bore of 2 1/2" and 2 1/2" stroke.

    If I find plans but for a very small model can the plans just merely be scaled up to fit?

    Regards Al

    As a general principle a lot (most) things that have to do with fluid (air is a fluid)
    flow do not scale simply.

    Thank you George Rhoades for the plans.

    P M Research does have a nice brass carb casting or available finished model but after a phone call their's would be too small. Modifications neccessary to get it installed (with a 3/4 pipe thread) make it easier to make one from scratch.

    Regards Al
