Re: Brand new Dynajet
gettylee,
I don't mean to rain on your parade but your Dyna-Jet is not new; someone polished the red anodizing off the head fins.
This has absolutely no effect on its operation even the fins can be removed without harm, but I can't fathom why any one would remove the coloring.
Also, your chosen spark plug appears to be larger than the original; a 3/8-24 Champion V is quite satisfactory if the ground electrode is removed. The plug might last longer if it is moved forward about 1/2 in. in the combustion chamber. It will be a little cooler there.
Always wear hearing protection! I suffer hearing loss due to my testing many D-Js and larger pulsejets when I worked for Tenney in 1949-1952.
I'm still working on my D-J book and hope to get it to the printer this summer.

Re: Brand new Dynajet
Hi,yes it is new,I bought two of them from Curtis dyna fog,I sanded the fins,to give it a little carictor, so it matches my homemade combustion tube,plus I won't get cut on them,I'm going to make another DJ & I'll leave it red, lol
Re: Brand new Dynajet
Here is what it looked like before I sanded the fins,I talked to Mauricio @ dyna fog,that's how you can get just the head assy.no combustion tube though, that have some parts left over also. Fun stuff!!!
