Need help to set idle

[Charlie ny]

I kind of see gaskets or washers under the jets too ,BIG no no....no gaskets or washers
under main jets.
I do hope you find the 'V' style nozzle bars.
Failing the above try blocking the small vent hole that you see in the nozzle bar
adjacent to the idle tube.......this would be under the category of experimenting.....
so do not do this on a permanent basis. This worked for me one time a long time ago.
