OK guys, I think Ralph and Kris have told me something that I didn't realize.
I purchased my 4 wire sensor from C&H and installed it on the aluminum bracket to work in my BME 102.
The bracket has a hole that the mounting bolt goes through and has some play in it.

Are you guys telling me that by moving the sensor left right in and out the play in the bolt hole, I can change the timing of the engine? The play may be around 0.010 of an inch or more. DO I have this right, if so, could the sensor be installed so that the advance is more than recommended and the engine requires premium gas to prevent pinging at idle?
