lawn boy dura force surge
I have a model 10550 lawn boy mower that has a bad surge when starting up and under no load. After the engine warms up its slighty better when under no load at full speed but still very noticable and if you pull the throttle to less then full speed the surge is aweful. Ive had the carb apart to clean the main and side jet with fine wire and cleaner and replaced intake gaskets but no differnce. Ive seen past posts on here stating to drill the main jet to a 67 from a 65 i belive and the side from 46 to 48? What type bits are people refering too? the number gauge sets go up to size 40 and get smaller diameter as number increases just like sheet metal but the posts said to use a higher number size? I never have this problem with any other lawn boy mower although this is my only dura force model. The fuel is also new but im just already sick of this mower and want to stay with only my vintage models.
