Any emission test tips or tricks?, I'll be testing soon... Options

[914zim]

Dudes:

I live in southeastern WI and I need to get an emission test before I can get collectors plates on my '76 914.
Once I get the plates, I will not be required to get tested anymore.

Do you guys have any tricks or recommendations on how I might help it pass?
I've replaced the plugs, air filter, fuel filter, injectors, resealed the tank (fresh gas) and installed a used cat, but I'm missing the air pump. I think my '76 came with an airpump installed from the factory, but a PO must have removed it (and the cat). I've also installed a good used (ansa?) muffler into which I've installed the used cat.

Once (if) I pass, I'll remove the cat and put the bypass pipe back in.

Any good tips? (besides lising it as residing in another county where testing is not required)?
Thanks for any ideas that might help.

try and get the car hot, all the air pump does is pump air into the cat so it can heat up and catalyze the exhaust cleaning it up. if you can get the cat to heat up you should be able to pass unless the cat is bad.

well that is what the air pump does on my Ford mustang.

hope this helps. you might not have a problem though depending on the limits that the state sets for your car. my car passed perfectly no probs and now i never have to emissions it so i am putting the rotary in!.

good luck
