I have stock honda 196, it now has open air filter and straight header no muffler (yet) what is recommended to change in the carb so it will run correctly ??
You have not told us what it is doining but I would say it is bogging on accelaration and back firing on deccelaration. You first need to increase the size of your main jet, you shouls start at .033" and go from there.
Chief among those are lift rates and duration.It may of had very similiar lift but there is a lot more to cams than lift measurements
