Been a while since I’ve been back, new job has me working a lot and took most of the summer to gut my boat and replace transom, stringers , foam and floor, after I put the motor back in and started to tinker with the timing to figure out my issue. I took valve covers off , pulled timing cover and distributor... started over verified cam and crank timing, spot on , reset to top dead reinstalled distributor. Still ran off spun around to tdc again and retarded to distributor 1 tooth and when I fired it up I started easier was idling high so I tweeted it down 650 rpm. Still running and camming really nice. Pulled out timing light and I had visible marks again set my base the reset idle , made couple slight advance spring adjustments, jetted carb down from a 74 to a 68 primary 74 secondary and she runs like a scalded dog. Up prop to 21 cleaver from an 18 4 blade ( the 18 was interesting and some fun) and can still twist 6500 rpm and launches pretty hard , I spun the drive coupler the last time out and couldn’t run over 3800 without free revving , coupler this year and a 23 cleaver to see what she does.
