I knew they would all bolt up, the bases are all the same and I knew they would all run but I wasn't sure how how much would be loss by throwing a unit from an M (for example) on my A. I have no idea if more advance is recommended for the C113 or less. Kind of seems to me that any of the A-140 units would be close enough. Really it's the curve that makes the difference more then what the final advance is set at right? I mean the H4 shoots straight to 30 deg no matter what the RPM is at, which works and had worked for many year but could be better hence the move to the battery ignition unit. K [Reply]   [No Email]

Original A and M tractors were the same. I mess with bigger tractors the most, total advance does make a difference if you drop a plow in the ground and pull at or near maximin load all day and using the recomended fuel. Especially with higher compression pistons than original. Going to find pistons with tops eroded or the top edges eroded down to the ring grove. Everybody does things different so I don't say much when I see the posts about setting the time by ear. I wonder what there doing with the tractor though. Especialy the 100 series up bigger tractors will sound like the time is retarded if set to specs. Saw enough piston damage on them when worked hard to know what happens. Toms post made me think of something else. IH furnished parts to change the advance on some mag equiped tractors when installing firecrater pistons.
