PCV? Normally the PVC hose would be routed to the air cleaner box, but I suppose it could go in anywhere between the air filter and the carb. Perhaps that air plenum is made for engines with and without PCV valves and yours doesn't have one so they plugged it.

That sounds reasonable, and I can find nothing else definite about it anywhere.

I'm still working on the Vanguard Twin V, and began to change the oil yesterday, and I'm still trying to remove the old oil filter; it seems welded on. I've tried all of the various wrenches and tools, and today bought one of the strap tools that use a 1/2" breaking bar, and actually ripped the strap in two. I hate to drive screwdrivers through filters and have avoided that; I can almost guarantee that the filter cannister will simply tear,

Anyone on here have any other tricks for getting stuck oil filters off? (I've already searched youtube, which seems pretty useless.)

Yeah, the screwdriver deal is the last resort. As tight as it seems, you're right that it will just tear it up. But you may have to go there - tearing it up that is. Get rid of the tin canister and the filter media and you may be able to twist it off with some big channel locks or a pipe wrench on the center tube if it has one. Or, carefully, use a cold chisel and hammer to try to turn the flange if you get it stripped down that far.

Before those extreme measures though, if the motor runs, I'd run it till it's hot. I mean HOT. Then see if it breaks loose.

I finally broke it with the three pronged gadget and 1/2" breaking bar, and then finished removing it with the 16" channel locks.

My first thought is that you don't want unfiltered air to enter into your carburetor which leads me to believe that hose originally hooked to a cylinder head breather vent that dumped oil overflow back into your carburetor to be burnt. The FDA now requires this of carbureted engines which means you get less fuel economy and more fouling of plugs and crude buildup on your cylinder heads. Smart people reroute their vent hoses to a cannister or dump it on the road. If you do this, you must plug the carburetor vent plug or your carbureted engine won't run or won't run well and you'll suck unfiltered air into your engine. Not sure if this is what's going on with your small engine. My frame of reference is motorcycle engines.

I have to remove parts off the front of my Harley to get the darn oil filter off because there's not enough room to get good leverage. I've tried every oil wrench on the market I can find and often resort back to the trusty screwdriver. That three pronged do-hickey you pictured looks intriguing. I may have to find one of those.

Both of the tools I used came from Harbor Freight.

Tangentially related… Last year, about mid-Winter my 20 y/o snow blower started having trouble once again. I’ve had it serviced a couple times in the past but I’ve been doing more myself lately; growing a bit. So I changed the oil and spark plug and replaced the belts. But it wouldn’t start. Fortunately we only had a couple snows left in the season so I shoveled. For this season I bought an aftermarket carburetor for $25. I never did that level of engine work before but I figured I’d give it a try before buying a new blower (which are pretty expensive for the size I need). A week ago I replaced the carburetor. Started on the first pull and roared with more power than it’s had in the past decade. Very satisfying.

This morning I accomplished a little thing, but it's a miletone for getting Pop's T back on the road.

What I did accomplish was to bolt the battery ground strap to the frame.
Easy-peasy, right? Well not exactly.
How it came to me was a cable came back from the hogshead to ground the battery, unlike anything I've seen before.
Illustrations show a ground strap bolting on the hole in the frame aft of the battery.
Of course my T doesn't have the hole in the frame and the closest connection is one of the holes where the battery
carrier bolts onto the frame channel and wouldn't you know, that bolt was missing so I had a hole just waiting for
a new bolt with a ground strap. The unfortunate part is that the battery carrier must have bounced around with a battery when Pop drove around because the bolt hole in the battery carrier refused the align up with the hole in the frame. When I did manage to spring it back to accept the new bolt,
of course the bolt was too short!
Now this has become quite a job, as I have to fiddle with this bent over, through a open back door, with everything upside down and sight unseen since it's inside the frame channel and the steel battery carrier apparently has an attitude when it comes to lining up. Add to this my eyeglasses decided to become loose and bail at every opportunity, apparently in order to add to my fun.

Anyway, the negative ground strap is now attached to the fame.
It's a little thing, but a milestone none the less.
