Continental y112

(quoted from post at 15:10:39 09/25/23) Does this engine have a PCV tap in the intake directly
above the carburetor? If so, there is a short hose with a
PCV valve in it, tapped into the tappet cover. If this hose
is cracked it will create a huge air leak.

The problem with it dying when throttling up or when a load's applied is a common problem on those Continentals. The governors get a little loose and 'hyper-active' over time. When this happens, they open up way too far when a load's applied and stall the engine out. To
confirm this is the case, watch the linkage from the governor to the carb when you go to throttle up or apply a load - if this is the problem you'll see it go wide open, even if you just throttled up a little bit.

Adjustment is via a 'surge adjustment screw' at the front of the governor body - sometimes hard to access. You loosen a jam nut then screw the adjusting screw it in a little to tighten things up. Usually half a turn or so is enough. You don't want to go too much at once,
or it won't respond as it should and also have trouble idling.

See this link, page 40 as the pages are numbered at the top of the page (which is page 45 of the PDF). There's also the 'sensitivity adjustment' spring: Usually it doesn't have to be played with, but if something's become misadjusted over time it's worth following the
instructions in the manual on how to adjust it as well.

Thank you sir! Unfortunately it was not the governor adjustment. I pulled the carb and opened it up. I do not know how it even ran. Never have I seen a carb with this much trash in it. May have never been off this truck since delivered in 69'. All passages are open and cleaned up good. Parts are soaking and kit is on the way.
Once the carb is done I have a transmission line to replace. That looks like the radiator may have to come out to get at the hose.
