I’m working on an article about the Silver Swallow engines from China. There has been some correspondence on this blog site under other headings, but it seems that it might be helpful to create a thread specifically for those engines. Does anyone out there have any knowledge of these unexpectedly nice little engines? In particular, information regarding serial numbers and the glow-plug models would be much appreciated!
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?
