RE: Ed's Ziroli B-25 Build
bigE-
I will watch your progress with interest. I also have the plans and glass for this plane. I was going to use the DLE 35RA in mine. I just put it in a Corsair and it is a fabulous engine and will fit very well based on my plans. You should also be able to also install the ignition inside the cowl. The B-25 plans show the thrust washer at 158 mm from the firewall and the DLE 35 is 160 mm in length with the supplied standoffs. I am attaching a shot of my 74" Corsair setup with the DLE 35 as it has a similar size cowl.
