Carburetor problems 1993 Mazda B2200 automatic (Japanese model)
My truck only have 94 K. I'm having problems in low idle, first i was thinking the spark plugs and the cables but everything is fine. Seems like my carburetor get some air that I can't adjust. I already check all vacuums hoses for air leaks and try to adjust the air flow but doesn't seems work. I feel a little shake in the low idle. but shakes when you mash the gas. The carb seems clean. Can be the head gasket under the carburetor base?

Need some advice!

Thanks

sounds like your carb might be a bit dirty and needs some cleaning and attention. does the butterfly have any carbon buildup??
does the shake go away after it warms up??

the butterfly looks clean. I swap the spark plug 1 with 3 and turn the engine on and remove a little dirty I pit it back but still the same. When she warm up work a little better but not perfect

if she shakes real bad, i am thinking you are having a bad burn somewhere. have you pulled all the plugs and checked to see how good of spark you have?? might also do a compression test.

Actually
I did yesterday the don't look bad just a little bit of carbon but the middle seems clean. This morning I can't get to work because she doesn't run every time that you pres the gas she turn off. I will check the fuel filter maybe is clogged

Finally I found was wrong! Had a vacuum hose disconnected and replaced my spark plugs wires. Now she runs like new!

Thanks for your comments
