Hi Ralph this is Bruce Swartfager how are ya havent seen much of you on here lately , any way i might send my FOX in to you and you can put a mechanical advance on it , i really dont care what you do to it just make it run like it should. I have adjusted the sycrospark every which way but loose and it still runs like crap. I know it dosenot make the motor run any better to have it polished , but when i got the 2.4 back from you a few years back you polished it up and make it run better it was the fpe with that fixed ign on it. It went from 6600 rpms to 7400 with the ign you put on it. My point is i feel if you keep your shop dirty then your work comes out about the same quality. I cant complain about any Brison motor i have had 6 of them now and they all run excellant and Gary treats people like you Ralph with diginity and respect . Also i have a 6.4 twin Brison which has the sycro on it and it runs excellant at midrange. All of my other ones are 3.2 motors. Just my 3 cents worth. Nice seeing you on here Ralph . By the way Ralph the Brisons are about 120 bucks cheaper because of the mechanical vs. the sycospark to buy new. Your correct they are cheaper to have the throttle advance compared to the sycrospark installed.
