What is this part? 420cc pred

[scatteredsun]

Sorry for all the threads and questions!

I'm learning a lot and I try to find the answer to my questions before I post.

There's a piece on this 420cc that I'm having a hard time identifying. I've been through the manual and its not on the exploded parts list or any other picture. I haven't seen it in any of the videos I've watched.

It's in the picture on HF's site but none of the documentation pics have it.

It's the small box hanging off the bottom left side in the above pic. It has a couple tubes that head up into the air box.

I can post some close ups if needed.

Hmm. Please remove the plastic air box and chase the tubes. I bet you might figure it out yourself.

 

[scatteredsun]

heh, will do tomorrow. my wife said it had to get out of the living room for the night.

 

[Whitetrashrocker]

Ahh hahaha. Start tearing the engine down on the dinner table. Take the governor out, you'll thank me later.

Do it now before you ever put oil in it.

I'm serious.......

 

[scatteredsun]

hah, I will definitely take the governor out before I fill it. I will NOT however, do it on the dinner table. My wife would make me buy another table after I was done. I have a buddy with a well lit garage for that operation.

It’s called a charcoal box, it collects exhaust fumes, more epa crap

CARB compliant model? Charcoal boxes typically collect fuel vapors, not exhaust. But yeah, emissions garbage.

Yes that’s what I mean

Ok, I figured it was an epa thing. I'm going to take the gas tank off and use the one on my kart. I'll double check but I believe it's got a venting cap. If it does, I can just remove this box and all the tubes yes? Do I have to block the return tube?

 

[firemanjim]

Take the EPA crap off. Put a tiny filter on the vent tube. Plug the hole in the air box..... Don't need the EPA crap and makes it look ugly..... Lol
Remove all of it. Plug hole in airbox . If your gas tank lid is vented , you're good to go

 

[scatteredsun]

I don't think a torque converter will fit with it dangling there so it's got to go!

What sort of tiny filter do you recommend? I could cut a bit of foam and stuff it in there with a hose clamp.

How about blocking the hole in the air box? hurricane tape or something more substantial?

This is for I use for the filter.

As far as the hole I just hot glued mine before I took the airbox off. Seemed to work just fine.

If your motor is exactly as pictured... Then the tank isn't vent with the cap. The hose with the 90* fitting, is the venting mechanism. It is a check valve, could add a small filter or just remove the hose... It for the most part isn't going to allow much if anything down into the tank.

Vented caps are the typical steel chromed ones, Seen on Honda brand tanks...

I wasn't planning on using the stock tank that came with it. I was going to remove it and use the tank that came with my frame. I'll double check but it looked like it had a normal venting cap.

hm, or maybe, now that I think about it. I may end up just using that tank. I was just looking at the area that has the tank and if I remove the tank I can use that spot for storage (hauling bags, tools, etc)

I vote you relocate the charcoal canister. Free and easy.

It absorbs the gas fumes so that if you park tbis thing in your house garage it will not stink up the joint. It does not hurt performance any. My 900 horse power Chevelle has one that I built custom for it to keep the smell down among other reasons.

Oh, and supposedy it helps mother earth. Show your kids you kinda care. But I am all for deleting some catalytic converters.

And another thing, the gas additives like e10 like to absorb moisture from the air. You have a lot of that where you live. So a direct vent to atmosphere might be bad.

 

[scatteredsun]

We'll see. I may have to remove the gas tank to fit the engine in. If I do, I'll just remove the whole thing.

If I can keep the existing tank I'll look to just relocate the thing. I won't know how well the TC will fit for awhile. That 40 series is expensive and I just used my fun money on the engine.

What? Seattle wet? Naaaaah *as the rain is blowing against my window*
