Rebuilding a 1979 5124
I thought I had a good deal on a preowned LB as the owner/salesman ('Dick faced' liar) stated that he had it for a decade and it worked perfect :thumbsup: Maintained regularly and he was sad to see it go:frown: He got a brand new big-wheeler with a bag and just wanted the little LB gone to make room.
I got it for $20.00 and I think I paid to much :wink:
Just home after a quick jont into the carwash
I was so happy with myself.
Then I start rippin into her and find all is not so Rosy.
There are some heavy pock-marks. One goes all the way through, 2 more are all most through. Paints blisterin on the shiny side of the deck!
So I got a plan and put it into fruition.
Glass done
2 coats of rubber truck-bed liner. - sorry Pics later :ashamed:
4 coats of green paint with wet sanding in between coats.
New (old :wink: cylinder) on top of totally disassembled and cleaned crank with new piston and rings.. Oh-Ya
Rebuilt motor with piston and rings. I cleaned 2-3 cups of grass trimmins out of the crankcase!! :shocked:
The reeds were suffed with grass = open! :shocked:
The carbon in the head, piston top, crank, cylinder, exhaust was stupid stupid stupid!! What do these 'people?' use for 2 stroke oil?
What do these 'people?' use for air filters? How do these people get work?
The piston definitely had been seized and he broke it free to sell "not seized!! Mother F-er!!!
The rings were seized into the grooves, the piston pin seized into the piston and the cylinder scored bad!!!
Time for some snacks and a brew er two. I'll see if it fires up tomorrow if I can get back to it.
Ps - the carb was totally STUFFED with vanish and grass. It is the 'Utility' carb and I don't know how to take the main jet out?
Anyone know?
Thanks LB lovers - cheers... :thumbsup:

Ya, I did pull the cord. It felt nice like there was decent compression. He lived on a busy/noisy street, I couldn't hear metal on metal but it had definitely been seized and then freed. Next times I'll always take my compression tester.

Yes, my only problem with this purchase was that he lied to me.
I don't mind fixing one up for the team. My buddy had a cylinder in a box that fit & he gave it to me, otherwise I would not proceeded. So a piston, rings, 2 cans of paint, a can of carb cleaner and many joyful hrs tinkering. :wink:
Just need a steel wheel, my rings to come in, a couple missing screws and see if it runs
I'm just getting started in this, so it's good experience, wouldn't do it again (with this model).

This is the muffler
This model of can doesn't have a pipe or single port for the exhaust gases to exit, instead there is a series of holes drilled around the perimeter of the bowl for gases to exit. The really big rusted hole is directly under the exhaust port of the engine so it exhausts pretty well straight out. That is not good for the economy, efficiency or noise. For best 2 stroke engine power & efficiency there must be a certain amount of back-pressure there, that is why high performance 2 strokes have combustion chambers close to the engine.
I don't know if this is the stock exhaust as there were a lot of things wrong with this example.
I'm going to take my 'F's' muffler off & see if it will fit, I'm confident it will.

You are correct Sir, the F and D mufflers are indeed very different..
F on left D on right
F inside D

Hey impalass,
I just checked Can-Post. It is going to cost $38.15 to ship a box 12"x12"X10" tall weighing 2kg, COD..
Fedex, $11.06 -> $48 depending on the service, no COD offered without an account so I'd need to get one set up.
I'm going to pickup some stuff an hr down the road. One Buddy has a couple used mufflers there. I'll take my old one & see if he has one compatible.
Don't discard your exhaust just yet. If we do this, I do need some bolts, 2 muffler bolts, 2 deck plate bolts and the 4 bolts that hold the cowling on.
Not sure I need the carb, mine is not to bad. You don't want or need yours?
Maybe franchi could stop in and pick it up on his next mower purchase, chances are pretty good he'll be driving right by!

Thanks impalass, those are exactly what I need.
The first link - I was going to mold jbweld up a repair.
The second link - I can't find the darn washer that grounds the coil to kill the engine. I have the other parts but lost the washer. :ashamed:
