I will start it with Electric Start, but it does not have any impediment to start it with a kick, just the biggest compression. I will use an electronic ignition, I take the S & S adapter to cone style.

 

Good looking motor! I suppose it's too late to install compression releases?

 

he has 4 plugs that do actually nothing but give you a location for compression releases

 

will that fit back in the frame. height wise

 

I see a 151 inch motor start with 10.8 to 1 with a ekectric starter......no compression releases. My 140 i put manual ones But i would be willng to bet one of my home bilt starters will start it using correct battery...

 

I have the right spark plug holes. This bathtub combustion chambers don't need dual spark plug.

It's only a millimeter longer than a Shovel. By using short pistons I have reduced the height 5mm.
