k241 runs rough

[cub1961]

this one seems to miss and the govenor surges at higher rpm. also seems to pop when changing the throttle too quick. i did the easy stuff like fresh gas, plenty of seafoam run through it and also made sure the gov linkage was correct per manual. any thoughts on what to try? i haven’t messed with carb adjustment yet.

Sound like the high speed jet need adjusted.

Check for wear on the throttle shaft.

 

[cub1961]

how would i do that?

 

[cub1961]

well i think this was an RTFM moment. adjusted high and low speed per the manual and it is running a lot better. still has a little putt putt but not bad.

Check for wear on the throttle shaft.

Aside for other issues, your note was a big part of my problem. Led to inaccurate settings, inconsistent settings with attendant surge/slow and also constituted a significant but not consistent vacuum leak.
