I installed a new spider injector from Tamerx. Not running well so pulled just installed plugs. Running heavy rich on #8. #6 and #4 looked pretty good, slightly rich on #2. #1 doesn't look like is getting anything, plug looked like it came out of the box. #1 and #8 are getting spark. The timing is off, got it close enough to run, but trying to find a scanner. Any ideas why this variation?
