I just started a rebuild of a 83 rx7 with a 12a engine. I just picked up this car last weekend and it has been sitting for a long time. I cleaned out the fuel lines and tank. changed the distributor, coils, wires and plugs. The good part is that i got it started however the bad part is that once it gets warmed up it stalls. Please help any input would be greatly appreciated.

 

all 1st gen 12a rx7s came with carbs.

 

in what way does it stall? at idle after it gets warm? when u come to a stop? need more info bud. why did u feel the need to change the dizzy and coils? did u verify they were actually bad?

 

yep, gsl-se(84-85)

 

Assuming that the dizzy and coil replacement was done correctly, you almost certainly have a fuel problem.

After sitting a long time, the entire fuel system will need to be rebuilt.
