I had to change the curve in my governor link too - it was fouling on things. The way I start mine is chainsaw style. It has a very crude, chainsaw-like choke with no spring-loaded "unloader" feature such as real carburetors have. So, I close the choke, pull the starter either once or twice, and it chugs then stops. I open the choke fully, pull once, and it starts and runs. I used your method until I looked at the choke and realised only brute force would work - now it starts more easily. I agree, mine was about fourth pull in warm weather if I didn't use the choke.
