Transition port cleaning tool

[jjsinaz]

Here is a tool I devised to aid in cleaning the transition ports (three small holes in the carb throat).
Cut a wire off a wire brush
Clamp it in a hemostat

Seems to work great, just don't be too aggressive as to enlarge the holes

That's the main problem. Those holes are a "Metered" hole, and putting something physical into it can/will damage that hole. It should be use ONLY as a last resort. (sometimes you have no choice)

I find that most of the time, going back and forth with carb cleaner and 100psi of compressed air will get them flowing again.

Duly noted and thanks for the additional info.
