hi guys well im trying to get to the bottom of my error.I broke the the Almighty Rule IF aint broke Dont Fix it...Two months ago i thought it would be a good idea to put Gumout gas tank cleaner in tank of a 1979sa.Stock except for headers and is Automatic.So you guys can stay with my Noobe (explaining).This a newer engine with a newly rebuilt carb.the gumout did its job and i had to replace filters.I (painful part) put rear filter on backwards noticed it wasnt running well and did althis STUFF instead thinking i might have put filter on back wards?fFooled with timing couldnt make a diffrence let sit over night.Next day wont start.So off and on over next few days i keep trying to start.Pull plugs dry plugs ETC.Keep tweaking with dizzyalso.This is after turning filter back around (mind YOU).So i get it to idle just ever so faintly and dies..Know it doesnt want to turn over.I can turn over by hand but when you almost get it turn One COMplete time theres resitance.CAN a starter be ingaged and make have some resistance?Anyway i better close this up or wont publish.Thanks for any support.
