looking at and reading brisons dead website i see where the engines are ionized except for the 2.4 I ordered and received a 3.2 and its not ionized. the website shows it as being ionized blue.no biggy.i had a lil problem with the ignition.the hall sensor slid back in its mount after running the engine for a couple minutes and the engine quit. i pulled the cowl off my new plane,the one i thought was ready to fly.i push the sensor back in place,thought maybe a fluke.it ran about 2 minutes and quit again.i called brison and harvey told me the set screws threads where suppose to cut into and hold the sensor on the timing ring. He checked several and told me they were all sliding and the set screw hole was misaligned.he told me to ca it in place or i could send it to them to fix.The plane its in is the gp wagstaff arf ive been waiting for since last spring.not wanting further delays i glued with ca.Solved the sliding problem. I carried it to field,fired it up let it warm up and taxed it around for 4 or 5 minutes,making sure it was flight ready.Thank goodness.It popped and spit while i was taxing it,coughed and quit.back to the bench.pulled the plug.no fire.sensor hasnt moved.i pulled the ignition out and sent it to CH ign. to test.CH said there wasnt anything wrong with it and that the new brisons timing ring setup placed the hall sensor too far from the magnet in prop hub with only .010 or 020 clearance needed. mine has about 1/8 inch clearance.when he said the new brison engines...........it made me wonder????????????.....for your planes sake check the sensor.im not sure if im returning my new engine or fixing it myself.I am sure i shouldnt have to do anything after dropping that kinda dough on an engine.have you got a new brison.....
