Those 1/4" plugs look very deeply recessed. How will you screw them up and connect the HT leads? My Triumph Dolomite Sprint required a special thinwall socket for plug changing and some strange long reach plug caps.
Best regards

Thanks for looking in Rodger,  There is enough room.....JUST!!!...... to get a reduced OD socket in...5/16 hex  (8 mm) with a 7/16 socket counter bore...  ( 11.1 mm)   I won't be putting the plugs in with a breaker bar I can assure you!!!....

That is why I was looking at 10-40 plugs so hard....but the value of 1/4-32 is I can get it started on glow plugs as a phase 1 effort, and then mount up sparkplugs later.  Thanks Vixen for staying on my backside and making sure I could do this.   It will help with debug later.

I'll be running it regardless on E85 with a small amount of oil added...as it will run well with either glow plugs or spark plugs and RC carbs in the .15 cu in range don't mind running the E85.

A 120 degree connector and a silicone boot should be good for a connection....
