First time ever using a pump on a engine so I need a little help. I have a new OS 160 FX and a new Perry Pump for it also. My questoin is where is the best place to drill and tap for the crankcase pressure fitting?? There is a prefect place for the fitting on the back of the engine but there would be no way to get to it to tighten it up........ Can anyone help me....or maybe have some pics?
Thanks
Randy

I found this post on the Forum and it is how I did mine. Purchased the fitting from Tower Hobbies when I bought the engine.
With the back plate removed, motor upright, from the rear, you can drill the top left screw hole all the way through, just make sure you use a small enough drillbit not to damage the threads. Flush the motor out really well to remove metal shavings and replace back plate using a 140rx pressure nipple in the top left hand hole.

You can also drill the hole out with the pressure nipple installed to prevent thread damage, as I recall, that's how I did it. Just use small enough drill bit to pass through the pressure fitting.
