I have a question if I go to p-port with slide throttle could I use
short elbow turned up and join to mount for holly carb with no throttle
shaft then long ram tube into top of carb?
Next what size bit to drill housing for intake tubes I have old milling
machine and can get? end mil to clean the hole so I need tube od. size
I can practice on damaged housing and think I can weld the tube?
Thanks Keith


I am sure it would run but I don't know how much power you would get because
the tuning would be disturbed having the carb in the center of the runner.
It is worth a try. Should be interesting. You could get one of those pressure
data acq systems and see what it is doing. You will need a lot of room over
the engine. Might work in a pusher. What kind of airplane are you planing?

Don't use a large drill. That is hard to do. It will make a mess of it. The
largest drill you should use is 3/4. Then use a progression of shell mills
starting with one inch. Then 1.5 inch and then 1.75 and then a 2 inch shell
mill. Make sure all tables and knees are locked down well and use a large
angle plate to hold the rotor housing securely.
