Here you go, #9
Don't think that's your problem, but it doesn't hurt to check them.

Thanks for the info Daviet.....now I'll try to clean them with wire.....BUT.....If this doesn't work, what do you

think is the problem???.......I've tried the atomizer treatment with Seafoam and also keep Seafoam in the

gas.....Other than this slow speed/idle stalling it runs great for a motor this old..

I always do a couple of simple tests when I work on an engine, spark and compression, to make sure the basic health of the engine is ok.
If those are ok, move on to the fuel system, make sure all fuel line connections are clean and tight. The low speed jets are only part of the low speed circut. You might want to go ahead and overhaul the carbs, making sure all passages and jets are clean, including the ones under the core plug on top of the carb.
