Tach adjustment

[Tony Repetti]

I just installed 2 450c reman engines and found the tach on the port side is 150 to 200 off from the starboard side,
. The difference on the photo tach is about 5 to 8 rpms. I saw some dip switchs on the
back of the tach but didn’t try to change any. The gauge panels came with the engines.
The starboard engine is close to the photo tach.

Thanks

Tony
