hey lowboy, no offense taken at all i all ears for anyone trying to help with this. i dont have a tach on the truck so not sure of rpm at that speed it doesnt sound like it is wound out or anything though.
i have not checked to see if the muffler might be clogged will do that today and repost.
when did the compression test last night 5 of plugs had normal look to them, however plug #3 cylinder was covered in carbon build up. could be from where it has ran so rough the last week though.
didnt remove the distributor but did check the shaft, no play there, and mech advance is working fine.
timing is set at 4 deg bftd.
