Lynco Port Gauge

[AMSOIL - Oil Twins]

How can a race team purchase the gauge for an OMC "A" motor? My engine is second hand and I have no idea if the ports have been modified.

Thanks,

The Lynco gage I believe is available from APBA.

Regular inspection gage pins can be used to measure the actual diameter, but to know if they are in the correct location relative to the crankcase center line, the block would best be set up on a surface plate and checked with height gage and indicator.
