Air by pass screw - wont hold idle

been having a bit of trouble holding idle lately

Tune the 34 pict
1 turn out air by pass
2.5 turns out for the mixture screw

After a days driving i have to heel toe to keep the idle up at lights.
Check the carb and the air by pass has bottomed out
re-tune and alls well

A day later it wont hold idle and the air by pass is bottomed out.

I have a lock on the engine lid so no one is fiddling.
The screw does feel "loose" and yes the O ring is there

Guessing it is a drop of Locktite 222

Anyone else had this problem????

Replace the O-ring ...😊

replace the O ring

and use a bit of Vasso or O ring lub and no dont use it down there although it does work LOL hehehehe

Opps 4 got while your doing one do the other as well

better of replacing both at the same time

whats the internals on the engine like? hopefully thats not the problem but lack of idle is one symptom

Nah - pretty sure it is the problem.

Stuch a blob of blue tac in the recess to hold the screw still and all is well.
Picked up a kit from CSC that has the 2 O rings.

Dave hasnt given back my KY yet so i will have to go to the chemist on Saturday

replace o ring both
