F100 Problem number one through ....?

Here may be one reason it runs like garbage:

It's got a garbage Prime Starter.

One of these are not like the other:

You can see completely missing parts, and even broken parts.

And below you can see the fixture that the above goes into, and it gots different screws holding it on! Someone been in here, and someone dint put it together right. But still, this is only a "Primer", and really only is needed during cold start. Still, when the motor is running it could be letting in too much fuel. Perhaps one reason it runs like gargage. But wait for it, there may be more!!!!

And here's the video of it running like garbage in case you dint see it:

I learned the hard way. I put a new head gasket in, and when I tightened the head bolts, what I thought was right, was wrong. I torqued it down on my bench, and what I thought was 90 degrees and the correct torque was not correct. I did the first one, seen it went to 45 ft lbs when I turned it to 90 degrees. And I found out later, 90 degrees should have put it at 51 foot pounds. Part of the reason was because I use the old head bolts. Which I know you should not use, but I did because this is an unknown engine, in which I may be completely rebuilding. But I did not want to do so without at least hearing it run. I wanted to know if there were any other prevailing issues with the motor before investing more into it.

Anyway, I have a new head gasket installed already, and it runs the same, like garbage. But I don't have new Prime Starter yet. And I burnt up the gears on the starter motor. So this project is officially ON HOLD pending parts....

And don't even get me started, on the starter motor:

I'm so covered up with repairs right now but when I'm not Slab I really like a problem, they are fun to me. I'm hoping to get to one of my project engines by this summer anyway. Good luck.

I have the 24hp Honda motor in the Side x side to build when the weather gets warmer. Also have the 1976 Hobart welder that needs some carburetor work and possibly throttle body injection

You mean this band of four?

This was yesterday.

Rojo yelled at me in a PM (not). He told me I should be using the service manual (he provided earlier) when assembling the engine. I thought I'd share my response (excuse) to him! lol

I did use the manual, but I did not have it sitting there next to me. I read it and wrote down only option one (on the 3rd step, see below)!

I did not see the 51 ft lbs option/alternative on that 3rd step. So when I torqued the head bolts down on my work bench, what I thought was 90 degrees put it at 45 ft lbs. And that's how I proceeded.

When I did it the second time I seen the 51 ft lbs specification on step three, and when I went to 51 ft lbs on the bolts, it was actually past the 90 degree mark, likely due to the pre-used bolts.

lesson learned! lol

I did not mention my other self inflicted problem.

I always think I know better. So, because I thought I'd be taking this engine apart again, and since I was only "testing" it running a little. I thought I'd do the smart thing, and not tighten the flywheel to specs. I figured "gootentight" would be good enough. After all, I broke three pullers getting that darn flywheel off the first time, I wasn't gonna go through that again. Well, well, well. It turns out, it wasn't the smart thing!

I sheered the Woodruff Key between the flywheel and the crankshaft! doh

The good news is, that flywheel was real easy to take off this time! :bash

And when you think about it, with the timing off a bit, this may be part of the reason I smoked the gears in the starter motor. Backfires while trying to start it, spinning things forcibly backwards. Don't really know, but a possibility.

And you guys thought I knew what I was doing. :Rofl

Oh no, I never thought you knew what you were doing.... :Rofl:Rofl:Rofl

jk

So here's the update. I did manage to get the starter motor working. I used parts from two broke ones, to make one working one, kinda. It's over run clutch is bad too, but I managed to get a compression test done on the one cyl that previously tested as low. I had a feeling the guage I was using wasn't seating correctly. Well, I got a new compression guage and I got a good compression reading. Yay!

https://www.crappie.com/crappie/atta...0-img_2099-jpg

Were the previous guage only reached 90 PSI on this cyl, the new one, a press in type one, got 150 PSI. yay

Things starting to come together for ya...Congrats.

Still cheaper than a new outboard or Outboard Mechanic's School. I can't say I have ever seen a broken Flywheel Key, a first for me.

Second one for me!

Here's the story about the first time I sheered a Flywheel Woodruff Key.

It was long ago, I was in my twenties, My buddy and I were fishing out of a square back Grumman Canoe. The canoe had a 3.6 HP Sears outboard on it. A storm was approaching.

We were on the far side of the lake from where we were camping, on Lake Carrol in Illinois.. We watched a squall line approach. We decided to high tail it back home. I had this little 3.6 HP motor running flat out through three foot waves. The motor was out of the water half the time.

We were coming up to a bay, and I turned to stay nearer to the shore. That was the big mistake. The canoe flipped. It's a longer story, but with 60 MPH winds and 3 plus foot waves, we were in trouble. We both had our life jackets on, but my buddies orange old style (I think they call them Mae West style) flipped off over his head and was gone. I had not zipped my life jacket up, and it had flipped up over my head, and i was under water. We both seriously thought each other were dead. Anyway, we did make it, my buddy floated to shore holding the plastic 6 gallon fuel tank, and I was able to pull my jacket back on. We lost all other tackle and fish poles, and we did not care. We lived.

OK, so as it turns out, that 3.6 hp sears outboard motor was running flat out when it hit the water. It would not start again. About a year later I decided to investigate, I took the motor apart and I found a sheered woodruff key between the crankshaft and the flywheel.

I don't float at all, scary to even read. The experiences we live through amazes me all the time as numerous are not so fortunate. Great share Slab.
