It seems as though my 1600 with C-35 cam and large ports,low compression had a problem I had never seen before now. I恙錕tice the firing order 1432 it can also be read as 4321. You may notice that 4 can affect 3 as 2 can affect 1 in terms of valve overlap caused by the cam. this will cause more vacuum to be pulled in by 4 and 2 resulting in a rich mixture here and almost no mixture in 1 and 3. with dual carbs, the needed vacuum must be able to be pulled from th other side. Mine had no balance tube. Drill , tap add problem solved. Thanks to everyone for the attempted help. Jasper Webb-J.W.
