All the tests on Jan 08, 18 were run with Halifaxhops distributor, the ones back in Oct 16 were not. That is another reason I am confused as to why the 750 that was running lean with a distributor that wasn't worth anything could out perform his distributor with a well tuned carb a smooth as crap power curve and a better proto!! My memory isn't the greatest, but I know the 750 didn't toss me around like a rag doll in the cockpit, and I will never forget the 650, with Halifaxhops distributor did/does!
