Hello all,
What thread size is the idle jet 5F7640 which is screwed into the carb body and extents into the ideal circuit in the float body. I thought it was a 1/4-28, but that doesnโ€™t seem to be thread. I am trying to clean up the threads in the carb body where the jet screws into.ย 
Thanks in advance.??????

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
