    Do you know what brand?

    My plane currently doesn't have electric. But I plan on wiring up a B&C accessory plate alternator which is good for 8amps. I don't think it would power an electronic ignition reliably due to voltage drop at idle.

With the washers you also get the proper clearance between the prop bolts and nose bowl. You might find that with that little more clearance at the back the cooling baffles fit better against the bowl and cowl. The washers are about 3/16" thick on mine for about a 3/8" move forward.

    I found a good picture of some engine mount washers at http://www.rvplane.com/?categoryid=10000&dayid=1077

    I don't have any additional washers other than the plates that come on the Lord mounts and it doesn't look like I have any washers between the firewall and mount either. But between the firewall and mount would be more difficult to place them because a center lower bracket/support for the motor mount bolts in shear, so offsetting it would cause the support to not line up. Any ideas how to place washer between the firewall and mount in this case? Does anyone have a picture of washers between the firewall and mount? Washers to move the mount off the firewall would help with clearance on that starter contacter also.

    Any opinions on washers in this location with my plane being aerobatic, only looking for opinions, not professional advice

    Thanks for the ideas.

    Since its experimental, there are non-magneto electronic ignition options. I'm not familiar with how they install, but something I'd look into. The modern electronic ignition systems are more reliable than magnetos, and Slicks are not the most reliable mags out there from what I hear.
