Duckpit Posted September 17, 2018 Share Posted September 17, 2018 Can anyone tell me why my 45's keep getting slightly out of balance, after a good high speed runThanksNick Link to comment Share on other sites More sharing options...
Comp Sec Posted September 17, 2018 Share Posted September 17, 2018 Possibily the spring on the adjuster has weekend and allows the adjustment screw to move under vibration.Mine used to do something similar. Link to comment Share on other sites More sharing options...
Molecular--Bob Posted September 18, 2018 Share Posted September 18, 2018 On my webers I had a tab on a lock washer fail, allowing the nut holding the linkage arm to loosen, which gave similar symptoms to yours. Link to comment Share on other sites More sharing options...

oilyhands Posted September 20, 2018 Share Posted September 20, 2018 Some ‘soft’ loctite on the adjustment screw will prevent it unwinding on its own.Oily Link to comment Share on other sites More sharing options...
7 wonders of the world Posted September 20, 2018 Share Posted September 20, 2018 Are you using a single air filter or a pair of separates...? Link to comment Share on other sites More sharing options...
Duckpit Posted September 21, 2018 Author Share Posted September 21, 2018 Hi, I was using a single air filter & carbs are a year oldN Link to comment Share on other sites More sharing options...
7 wonders of the world Posted September 21, 2018 Share Posted September 21, 2018 Thats the better option as twin filters allow the carbs to vibrate at different frequencies which adds to this problem, you can remove the spring under the adjuster screw and replace with a lock nut though.

elie boone Posted September 21, 2018 Share Posted September 21, 2018 Likely the adjustment screw has eaten into the tab it rests on. Link to comment Share on other sites More sharing options...
