Allright I took the stab at it and it worked got my idle timing better than it ever has been. Only thing is my cruise timing is low. It's lard 18.5* around 40% load if I lightly hit the trotted to maybe 60% it goes to 30* give or take a degree or two I did the optimum spark tables how they are told to do and I set the difference to around 25 in the cruise area ad still nothing
