I have the OG charcoal canister hanging in my engine compartment and thought about hooking it up. A couple questions though.

1. Will it have any affect? Good/bad/otherwise
2. Where does it connect to? The pictures do not show this.
3. Should I do it?

1. It definitely has an effect, takes away your gas smell.
2. It connects to the air cleaner/oil bath, I think that big hose you see coming from the back is connecting to the bottom nipple on the air cleaner/oil bath. On the other side there are two nipples and the big one goes to the fan shroud and the small one goes to the nipple sticking out of your firewall.
3. Yes, yes you should.

I said nipple a lot in the post. Nipple.

Haha yeah I should have added the new manual is on its way so all I have right now is your collective wisdom.

You don't need a new manual. Your old greasy worn out one will work just as well.

Hiya Caleb,

In order..........

1. Replumbing your M-26 system will have absolutely no effect on your engine's power, mileage, or economy. On the other hand you will be routing hydrocarbons (the smelly stuff that can cause cancer) to the carburetor for burning.

2. The 12 mm hose coming from the rear of the emissions canister snakes around on the ceiling of the engine compartment (as shown in your picture) then downward in front of the rubber air tube from air filter to carburetor, then rearward to the port just next to the retaining clamp on the bottom of the air filter.

The 12 mm hose from the front of the emissions canister runs to the left and connects to the fanshroud port located on the fanshroud's right side.

The small 3 mm hose from the small port on the front of the emissions canister connects to the metal tube protruding through the bodywork at the extreme upper right hand corner of the engine compartment. When you check this out you will notice that the tube is not the same size as the port on the emission canister. That means you will have to rig up a hose with a small end and a larger end.

3. Sure you should do it. The system when working properly takes NOTHING away from the engine and scavenges (it's not a passive system - it draws hydrocarbons for burning) a potentially harmful substance for burning. Do it!

Do be aware however that for the system to work as designed the emissions canister must be free-flowing and not clogged up with dirt, crud and moisture - and many of these canisters are in less than great shape on the inside. So be sure to check out that canister too.

Thanks Mike, great advice.

I will go poking around in there this weekend and see if I can get it all hooked up.

FWIW, you might consider replacing the charcoal pellets inside the canister.
I picked up a container of activated charcoal pellets from the pet store and replaced the original?! contents and it was dirt easy. The metal ones would be a bit trickier to refurbish than the plastic was.
This and making sure the gas cap is properly sealing the filler were the 2 best things I could do for ridding of that fuel smell.

P.S.

The charcoal canister most certainly can have an effect on driveability.
Stored hydrocarbons give a nice rich vapor hit to help light the engine. Paradoxically, it even helps hot engines on hot days.
