Hi This question is for Jody, So far I have made 3 each of my own 55 CC engines using the DLE 55 cylinder and piston & ring. Well I got the first cylinder and all was well it looked alot like the DL-50 with the porting and so on. The next one I recieved was a much better casting and the ports was very smooth and clean, plus a little bit larger. The last one I just recieved is totally different ,has the eye brows so to speak in the transfer portsand the boost ports goes down to the bottom of the cylinderinstead of stopping approx 1/4-3/8 " from the stub end
What sort of running changes is this going to do to the engine ad does the case itself have any changes made to it to accept the boost ports being cut that way.
Thanks in advance.
Richard.
