312-8 exhaust valve & port

Recommended Posts

I was settin' in the shed havin' my 1st coffee & a cigarette. A reply in my original post about the exhaust valve kept eatin' at me. "Looks like a food fight goin' on in there". I got to thinkin', carbon is black, this crap is brown. I got a pick and poked around; it crumpled. I have never seen carbon crumble. I remembered the homemade muffler had some big holes in it so I removed it. Fired up the air compressor, put on a 12" blow nozzle, stood back & blew around the exhaust. Crap went everywhere, then a mud dubber nest came out.

The "food fight" comment was mine. I'd say that if not cleaned, the exhaust would have been a mite restricted. Best to find that stuff now. And luckily none of the winged critters were home.

@CD Long Jr   hard to imagine  what this guy was doing  , or basically  not caring  about  how any part of this worked , never  picked up one like that  , as stated ,  a tank clean out  as well as a  separate  heavily treated gallon of fuel  , lets you  enhance  running and adjustments . without question , that rislone zinc  will help cut / remove that  engine varnish . that engine heat  cleaning ring flush , has an amazing effect on neglect . have it in all my engines , zero smoke , also  2 fuel filters , 1 close to tank  another  close to carb , drop carb bowl  , probably  loaded with crud. would also  replace  all existing  fuel lines , fuel hose breakdown is very common,  sta bil fuel additive in all my  stuff , no issues at all , stay  with it  , pete

My grandma used to say "all the Lord's creatures serve a purpose", but I have yet to uncover what some of them are... :lol:

They provided targets for my Red Ryder in the pole barn i had when we lived in Ky.  Got pretty good at knocking them off of the rafters that way.

Other day I was helpin @Achto with a K91 and there were dauber nests in the head & engine fins. I tried digging them out of the head with the jack knife and they were like concrete. Them devils can be worse than mice. 

I've got outlets in the overhead of the lean to on the warehouse for battery tenders and every one the ground hole was filled with a nest.

Be sure to wear ear plugs when you are hanging in the shed!

Dang near ... :lol:

Funny thing is I never see them. I don't think I would know what one looks like without googling.
