FROG 349 R/C needle valve

Paul Venne has sent an inquiry regarding the needle valve for a FROG 349 R/C in his possession. Can anyone advise Paul?  It looks like the spray bar is not correct. It is a double hole and the holes are only about 1/4 of the way across the carburetor barrel opening and if oriented side to side they look very restricted or flow resistant. Paul’s question is – is this original??? On contemplation, it seem that if both holes are in line with the axis of air flow it might run, but Paul  wonders. Anyone have experience with a problem like this or specifically with this engine in R/C form?

  2. Adrian,

    I have an original H/s engine with what may be a Dooling brothers initials crudely scribed on the top of one of the exhausts,..
    I also have a Bungay 600 original, serial 150. I’ve run it and it is smooth and a fine runner.
    I also have the Orr and 2nd model Ball 60.both originals.
    I have a original YJ61JJ ignition new.

    1. Thanks for that, Walter – nice collection! What’s the difference between the first and second model Ball 60?
