Back in California I always made sure I used a good quality name brand gas before I went to get the test done. Make sure the engine is properly timed and make sure that the mixture is set right on your carb so it's not too rich or lean.

I've heard that aviation fuel burns with fewer hydrocarbons... also heard of guys cutting gasoline with rubbing alcohol to lower emissions...

Can anyone dispell/verify these "wive's tales"?

Rubbing alcohol dosen't sound real healthy for pump diaphragms, seals, o-rings, etc.

Just put some dry gas in it and retard the snot out of the timing just before you pull in there yard. It will go right through!! Then when you leave reset it! It won't have any power but it will pass! I've had cars show no emissions at all. The guy thought I shut it off!!!

I always lean them way out and retard the hell out of timing. They run like crap, but pass.

Yes alcohol works great...same thing as Drygas just alot cheaper, some people like to use the Drygas cuz the label says it's for your car. Isophryl alcohol is isophryl alcohol. Retard timing as posted and change that oil before you go in! Letting the engine be good and warm helps too.
