hey guys, have read 100 posts on ignition upgrades, including the JeepHammer wikipedia, but am still missing something. Have been running a Howell TBI for about a year with great results and just installed a MSD 6A and now she's not cranking.
Per the MSD Troubleshooting guide, I checked and am getting a spark from the MSD. I have an '82 but constantly find its '81 tech (was non-comp carb, independant duraspark).
Only link between the ignition and howell is the white tach wire that feeds the TBI computer. Do I need a tach adaptor inline before the TBI knows whats going on? Any other troubleshooting suggestions?
