Good day gents.
Last year I got my 72' running for the first time in 30 years. It has 25k on the motor and the PO and only owner is my dad. I put about 1000 miles on it but always had a back fire when I decelerated. I hopes of solving the problem I cleaned my carbs a out 10 times, New filters, plugs wires, battery, exhaust, ex gaskets... ect.
I am looking over my time this winter and had a few questions
I have gone through the standard cam chain adjustment, valve adjustment, gapped points and did a static timing adjustment. However when I use a timing light I can't get both the left and right to fire at the appropriate time. Either I can get the left to fire at the "F" Mark and the right is too advanced or I can get the right to fire at the "F" mark and the left is too retarded. I am adjusting them both independently but there adjustment does not give me enough to get me into the right location.
Any ideas?
Thanks in advanced
