Twinshockandy Posted December 15, 2019 Report Share Posted December 15, 2019 Hi Jordan, 123 monty has a perculiar 'selection' shaft which can cause issues, (end away from gear shift lever) = on mine it has been repaired. Maybe's worth an casing strip to investigate. Parts for this model are not the easiest to find.............mines now down due to finding cracked flywheel, and none of he usual parts folk are able to help. all the best Andy, Quote Link to comment Share on other sites More sharing options...

Just had a look and he is listing a cota 123 kick start drive gear items. as well as transmission items Hope that helps Andy Quote Link to comment Share on other sites More sharing options...
