Hi there..

I would like to know the difference between the choke jet and main jet since the both is the exact same size in the part.. but the holes are slightly difference in size.. so I would like to know which one is which since I have misplaced both to have it cleaned.. so now I can’t tell which is which.. Help please..

by the way I’m rebuilding the carb on my 2005 yamaha bruin 250.

Thanks again
