i nd help for a two barrel carburettor on a 626 hatchback

[kdamize]

i nd some help to tune the carb. it is actually running on a lean mixture. the engine warms up quickly and it backfires in the exhaust pipe. i have tried to search for a pic but there is no one available. could someone please help.
thanks

What year is this thing? WHere do you live? How many miles? Engine condition? I'm sure your carb would benefit from a good blowjob (remove the horn and clean her up) but until we know more about it I don't hink anyone will be able to help.

I've used the colortune for my carb. 83 rx7..might help with your carb adjustment...but definately more info is needed

its a 626 1991. its a 2l 16v two barrel carb. it has done approx 137 000. the engine is still good. i have done a servicing on the pcv valve. dismantle the air filter, the carb and cleaned it throughout with carb cleaner. the radiator has been dismantle and cleaned. even the motor block has been dismantled and cleaned with a water pump. all the pipings of air and oil has been replaced.
