when driving, if i lift the throttle slightly, she starts to buck , full throttle release.. no problem.just if slow down a bit in traffic..( LH jet 2.2 )also i cannot pull pass 5k on the tach.( oh yes, the car is a 1984 alfa romeo spider. otherwise the car runs fine on the LH jet,)she not pretty right now, but getting close

 

this car is a 1984 alfa romeo spider.. i took of the crappy L jet, and instaled LH jet off a 1986 volvo..

 

offhand, I'd say time to use a gas analyzer on a dyno to verify the mixture is in the right ball park all over the range of rpm and load and throttle
