Bubba I have three of your flathead distributors that work just fine. All are on engines with the aluminum timing covers. Today I switched one to an engine with a cast iron cover. I assume that it will work fine even if the gears are not fully meshed. Should I cut off the shaft that extends beyond the gear? Thanks, Pete

We machine each distributor to fit the best of all the different covers.

The lower shaft is approx one half what the actual merc would be to work with all the units.

Shouldnt be a problem assuming it doesnt hit the bottom of the cover.

The lip on the housing should fit correctly as well.

The gear mesh is set to ride below the gear. So as to push upward instead of pull down when running. The gear rides a little below the center line of the cam gear.

The gear mesh is pretty loose even on the stock flathead as theres no acc drive ( like a oil pump etc) to apply torque etc...

Should run just fine........

Unless I'm really missing something here, seems to me the gear on the bottom of the distributor is pushed upward by the gear on the cam.

Richard,
That is a clever markup of the timing gear cover. Makes the mesh easy to understand. Thanks

Bubba, you get more stuff right more of the time than most of us could hope to do.

I got tired of drawing circles in the air with both hands every time I thought about that.
