RE: Magnum 52 XLS
Thats what I did to mine also used a carb from a 46FX and now the engine runs like a OS and has gobs of power .i'm going to tear the magnum carb down and do some measureing and see what the difs are ,a person may be able to improve the stock carb to run good .Mine wouldnt transition well and the result was a flame out about half the time ,and it didn't seem to matter how it was adjusted.
