Well first off this wouldent have been possible without tons of info an help from Morris so thanks a bunch man I appreciate everything... 2nd I so cant beleive how fast this thing went on its 2 only gps pulls with new motor combo,carbs,pipes,fuel system etc etc,concidering its got 70:1 premix in the tank an a blend of MS 109/93 to be safe... Still pretty fat on the carb tune an still on the the short 16/20 solas prop with my softest timing map in.... 92 degrees an unsure of humidity but it felt pretty thick.... First pull which was probably 175-200 yards it GPS'd 75.7MPH..... Went back an checked the plugs an made another 200 yard pull an it GPS'd 76.2... Hope to start closing that 80MPH mark in the next 3-4 weeks..We'll see what happens... Btw anyone know whos gps'ed the fastest on a Ultra 150? Thought i saw one up north built by skiworks go 81.?something.... Just curious an looking for my bench mark ...
