I'm using a ZDZ80 with aluminum standoffs.
Presently standoffs are bolted to firewall box and engine to standoffs.


I'd like to add some right thrust, somehow I suspect just adding flat washers behind one side of the engine won't work too well since the engine will no longer have a flat flush surface to mate against.

Any suggestions or what have people done before ?

Thanks,

Put the flat washers under the left side of the aluminum standoffs between the standoffs and the firewall. Works fine for me.
