bfarm, yes i have checked for fault codes, when turning on the ign it will not flash a code. in addition to checking for codes, i have checked powers and grounds to the map sensor and have monitored sensing voltage to check for correct voltage atmospheric and under load. both check good against repair manual.
the only thing that i have done that has changed anything was install a stronger and weaker spring that goes between throttle brackets and governor brackets. both the stronger and weaker spring made the surge faster. I recommend him to try replacing the $2.68. If that fixes it, all i can do is laugh at this point!
