Guys I'm having slight sputter like it's missing, just for few seconds after cold start, what could be the issue.
I have checked
Plugs
Ignition system
Timing
Fuel
Auto choke
Cleaned carb 2-3 times
Nothing seems to be making a difference, what could be the issue. It happens under load after starting for few seconds only like accelerating from stop or pushing it with ac on. After few seconds it becomes normal.
