hello ... i have a 1990 sammy with a 1.3 lt that was throttle body that i turned carb for several reasons ... now i tried to change the coil and distributor to carb version but it wouldn't fire , so i used the injected engine`s coil and distributor. now it does fire but i am thinking the vac advance is not working seeing there is no vac hook up on the distributor .. so how can i fix this ? and i am running a weber 32 36 carb on injected head from my 90 and the bottom end off of my 89 and intake off of my 87parts rig . is there a way to hook up old school coil with old style distributor ? another thing i am only getting 8 mpg as it is running for some reason any ideas ??i am about to torch it all lol kidding never do that to my sammy .
