Seafoam and plugs for tweety....

Pulled the plugs and added a can of Seafoam each cylinder. (4 cans) Then I finally drained the oil that came out near new. I pulled the engine through with the fan blade and #1 and #2 cylinders splurged out the plug holes. I then got tired of pulling the engine through in gear (oops) blocked the rear tire and continued. #3 and #4 did not splurge. Where did the juice go? Now I need to go back to town, get another two cans and do 3# and #4 again. Drain plug is out and if the cans pour straight through. . . holes in pistons? Oh yeah. I also remembered the updraft carb while the Seafoam came out the inlet... i so smurt. Plugs looked decent upon removal. The wife has gone to town to pick up a new 6V battery. This sucker better not be toast.

All the juice must've drained past the rings and my compression is back down around 50. Doesnt seem to be sucking much gas up as plugs are dry but gas does pour out carb when I'm not cranking. Think I will try 12v on the starter to spin it faster. Hows your seafoam experiment coming Bruce?

I might check it later today or tomorrow. It's a few miles away. I'm hoping I can get it started and that will finish freeing them up. I have one cylinder at 95 so I'm surprised it didn't pop a little. It may not have had compression before I lived it.

Bruce, You say Later today will be hook 12V to the starter and give it a spin to blow it all out, compression check.

I wouldn't spin it over yet not before rolling it over by hand at least 2 or more full turns to avoid bending valve stems on stuck valves.

I did that yesterday. After I replace a bad injector on my (everything new) early '94 7.3 idi turbo F350 crewcab dually, I will put the 12V to the tweety engine.

Would be interesting to know compression prior. Hooking to 12v is a interesting idea. I was think of towing mine. Probably soak it a few more days. I should take the carb apart but I'm pretty sure it's always had good gas and it was dripping some out the intake however I dont know if it has enough vacuum to pull it in the top end. My compression is slowly coming up. Maybe in a few days it will be up to spec.

What kind of seafoam are you using. I'm working on a 8n and all the cylinders are low with the worsted being 40psi. I put pb blaster in it first then I let it soak in paint thinner and atf overnight. Today it was up to 50 psi. I may have used something else but that's what I had on hand. Put a little more mix in it tonight and will let it sit another 24 hours probably.

Oil the cylinders and see what numbers you get. Oil being a slightly better sealant. At 60 PSI, I would fire it off, get to temp and recheck comp. It might be all you need to get the rings to come back to life. Ask me how I know that one. . . After I collapsed a set of rings. . .

Seafoam Gas and oil treatment. Pours like water. My figuring was to get into the valves and rings, free up and a light case of lube.
Later today will be hook 12V to the starter and give it a spin to blow it all out, compression check, install new plugs, new battery, file points, a shot of ether and see if it woofs. I figure anything over 60 PSI should start on 12V. I imagine might not start with 6V on 60 PSI.
The comp check will just be to see if I have a very low cyl and not so much how high is it. Starts, runs and does not smoke like a banshee is my goal.

Tweety is a Harry Ferguson. Overhead valves. Does sound bad, what does compression check show? Plugs look like normal did with leaded gas. Not black like today.

Tweety supposedly has been sitting for 20 years. I figured Seafoam might just juice things up before spinning it over under power. Tomorrow will be fill with oil, install new filter, 12V on the starter and blow out the cylinders. After that will be a comp check with 12V and then install the new 6V batt and see about spark. Probably right after filing the points. I will first fire it on ether before having to pull the gas tank off and clean out the black lagoon inside the tank.

Shaun; Tweety is an 8N that Bruce bought a couple of weeks ago.

"Tweety" got it's name from ArleninOR. It is an 8N. The Fergy TO-20 came home a few days ago and will get parted out after I pull the front weights. Two tractors in 10 days and I have to make something happen soon enough to smooth the ruffled feathers of "She who must be Obeyed."
Well dear, I did get the Demonstrator working again... temporarily...sorta. 12 tractors now? Whose counting? I am hoping to keep 4 or 5. Eventually.
