Strange Vibration

[tommyardin]

Hi there.
This problem only started after i cleaned the cabs. The problem occurs when lets say i am on 5 gear and slow down and switch to 4 and after that try to pick up speed. I guess fully closed to fully opened.
Correct. When i open the throttle wider it stops and pick up speed.
I think block pilot jets might be out of question since i cleaned the carbs. I think it might be the mixture screws.
The mixture screws factory spec as per manual is 2 turns out. At the moment they are 2 1/2. Should they all have the same turns?


But my question is if the issue is the mixture screws how do i set these to correct this problem?


I will do the test that you s uggested and see. <<<<
I will let you kinow


Thanks for you info.
