smog gone

[bbqbill]

i`ve taken the smog stiff off my 76 l20b and was wondering if there are any tuning changes i need to know , or does it not make a diff.

[420n620]

how is it doing

[bbqbill]

i changed the head gasket and timing chain,pulled the smog stuff ,now i cant keep it running?

[Llittle_Llama]

You might have a Vac. leak, just a thought. I would start with that if it takes throttle to keep it running.

[dat77sun]

probly a vacuum leak, or maybe somethin in the carb

[datzenmike]

There are only a few ways to do this right, Post a picture of what you've done.

If it's the stock Hitachi, there's probably a problem in the carb, and those ones are virtually immpossible to troouble shoot. If you've got all the smog off, you might as well go with a Weber, way more reliable. Getting rid on smog is a bitch, and like Mike said, there's only one way to do it propperly.

i found the vac.leak.runs good now. started on the drivers side floor.

The weber works great with the smog stuff off. I have also heard that you need to make sure the air injectors in the exhaust manifold are removed and plugged to get the engine running at its best.
