try mcmaster-carr for ceramics

catalog page 3531 at the bottom

also search the site for ceramic tubes

Thanks Gregs

That  would have taken me a while to  find .


At    $  85.   for  10 pounds    it is  a little  out of my  budget  at  the moment ..........but  it is  doable in the near future

OUCH!!! $85....lol but it does seem that the two-part casting compound will work!

"Two-Part Casting Compounds
Easy-to-mix casting compounds capture intricate details when casting prototypes, molds, and linings."

"Alumina Ceramic    -200? to +3000? F    1800 psi"

but.... 10 pounds should make you dozens of plug sets...LOL

Cap70: I cant wait till you post details about the latest engine trials!!! I hope all works well for you.

   Here is simple circuit for engine timing modification to any angle.

Engine timing modification circuit is pending for new engine, not yet tested.

Use bridge rectifier and capacitor on magneto to get 12V.

Search for CDI. you can get more ideas.

Cap

I got the cap discharging when it hits about 280V it jumps back I have been playing with the freq and the freq on
the flyback in was abou 5Khz this produces nice plasma spark but the cap does not discharge if i take this down
to 100 - 300 hz the cap discharges. Also the transformer on the other side with the cap the frew is about 5Khz I am
going to try and up that a bit but I need to get another one (I am using a radio shack generic ATM) I did get the cap to discharge
adn I rpt a bit of water on the plug and I am getting blue plasma and some redish glow for a moment then it goed back
to the blue arc again. So the issue was a combination of the freq, MORE diodes and a resister on the + of the cap about
400K then I am seeing somthing different. When I do put some water on the plug NOT shorting) like I said I get some red sparks and poping. How loud should this thing pop? I assume varily loud. I get a very high pitched screaching off the cap also but no loud boom,
bang, just a craclke.

I am going to replace the transformer on the cap charging circuit and allow some more current through I just relized that the transformer
I am using is only 500ma lol  this should charge the cap faster and create a better bang!  I will let you know how it works out.

Nice Ieda on the timing I started to put together a circuit to do it but yours looks like it should work.

Later,

For some of you guys that are working with smaller engines, single piston, Briggs&Stratton ect. If your looking to change the ignition timing, simply remove the keyway in the flywheel and move flywheel to desired setting. Now tighten the flywheel down, tighter than normal but don't get crazy. I did this on racing go-carts for years and never had one slip.  Of course if possible use a degree wheel so changes can be recorded. Great work guys!
