With a blown head gasket the engine will still run with the other cyl. Look close on both sides on gasket from the piston to valve push rod hole in gasket, that's where #2 cyl will blow out the most. Mostly from the heat from the muffler close to the head.
The noise may have been the compression release stuck out or the engine run backwards like a dieseling.
I don't think this is it, but check you flywheel key to see if its sheared. I told a another gentleman to do this a day or two ago.
I still cant understand why it wont start or run, even if one of the cyl or head is bad.
I want to get this thing running, then worry about the smoke and noise.
The gaskets form what I see look fine. The second exh pipe looks a little more wet, maybe? #2?

Yes, I agree. I was just thinking the same. Get it going then worry about the rest.
At first I was trying to do it all and ready to go. But that ain't going to happen in a hurry by the look of things.
So get it going first.
I'll revisit the fuel - manifold carby pump.
Maybe run some fuel through manifold see it it leaks.

I didn't pay attention,I was addressing the blue smoke,lolA engine will run with out a oil ring.
You say it wont start and making a noise.
You are saying it wont start or run. But yet it smokes when put a little fuel down the carb and it tries to start.
Is it oil smoke or a rich fuel smoke?
There is a compression release on the cam making the noise in the case. If you have heads off crank engine over to see if noise in still there.
With heads on you can see the rockers dump compression on #2 cly if working proper. The rocker will move around .008, very little.
It all most sounds like two things going on.
flywheel key to see if its sheared.
quickly took bolt off and flywheel key looks ok - it's in place and straight, so I assume it's OK.
Called away for a trip interstate, so won't get back to it now for a few days.
Cheers...
Agree that it should still run on one cylinder. Most likely a fuel issue. Will somebody take a look at the picture of the head he posted. It looks to me like the exhaust valve is pulled down into the seat. Could it be possibly that this has been running on one cylinder for a while, and the good cylinder gave up the ghost.
Thanks for your help.
Has been running really well until this point. "Firing on all two" through thick and thin.

Back again now, and getting frustrated.
Put a new carb on, new gasket. Carb and manifold torqued to correct specs.
New spark plugs, gap correct (just in case).
No go. Doesn't even cough.
A couple of attempts with fuel down carb. (it always fires with fuel down the carb)
Immediately after I had the fuel line off and retested that fuel was being pumped through.
Also noticed that the oil sentry wire was off at this point.
It did fire once of it's own volition and went for a few seconds (like 1, 2, 3 from exhaust)
But, have not been able to repeat this.
Checked fuses etc, all seem ok.
It has me completely beat now. What could it possibly be?

Quote, Checked fuel line, pump & solenoid fuel to carby OK (actually now I think about it when removed solenoid, fuel runs out, so fuel getting through). Thoroughly cleaned
The fuel solenoid is working?
Do you have power to the carb solenoid?
Did it come with a new carb or did you install the old one to the new carb?
Did you see it work or can you hear a click at the carb when ya just turn the key to run?
Did you check the fuel pump. Remove the fuel line from carb and crank engine over to see if it will pulse fuel.?

Thanks Deerlane.

Did you check the fuel pump. Remove the fuel line from carb and crank engine over to see if it will pulse fuel.? Yes, made sure it pumped enough to fill bowl in about 5 to 10 sec.
Makes me wonder, if the new carb does not have a solenoid, does the solenoid wire need to be connected?
(I do plan to put the solenoid on when I finish, as on an old mower the float valve leaked over time and filled the sump with fuel.)
