oh, boy, look at that pile.

 

[Russ2251]

Most are junk. I wouldn't take anything older than 1998.

 

[freakboy]

i would steal the decks i wonder how much you can get for some magnesium and its fun to burn if you got a weldin mask.

 

[porsche930dude]

It sucks when people give stuff like that away for free because most of the time people just scrap them when like he said most of them would be running in 10 minutes. Although i think since scrap has been down people are salvaging more

 

[Russ2251]

Very few magnesium decks were made.
I'd be very surprised if he had more than 1 or 2 out of the bunch.

 

[EagleTalons]

Why did they use magnesium?

 

[freakboy]

Same reason they used them in wheels.

 

[motor_head]

dude i just watched that vid wish i lived up there
as for russ's comment about not taking anything older than 1998 i'd rather have a good old one rather than a new one most of the old ones were way better built.

 

[Jerryburger]

Wow! I'd love to have any of them to mess with, too. Too much potential in those motors to pass up.

 

[Russ2251]

most of the old ones were way better built.

Not in my experience.
DuraForce far surpass the earlier models by any criteria you wish to choose.
DuraForce have better porting, twin ball-bearing mounted crankshaft, more power, lighter, and more easily converted over to do what I require them to do.
Models A, C, D utilize bushings for crankshaft support and once they are worn out, crankcase must be replaced.
Only weakness in the DuraForce is the CDI pack.
They do fail on occasion but they also can be easily repaired once you understand why they fail.

Vibration?

 

[Russ2251]

Moisture.

 

[jr dragster T]

Ohh ok. What do you figure the cure is other then just drying it out with the oven and WD-40 method?

 

[Russ2251]

Baking is only way out. Works most of the time. Sometimes it's a permanent fix...sometimes temporary.

 

[jr dragster T]

Ohh ok. So when the Duraforce engine is being used in go kart weather and not outside in the rain on a lawnmower, Do the coils still fail from moisture?

 

[motor_head]

guess i haven't had alot of experience with lawnboys but all the 4 stroke motors ive worked on the older ones were way better built

 

[Russ2251]

Yes, but don't think that this problem occurs often.
I got some really great deals on engines that had "No Spark".
As a result, they were sold "as is" for parts.
I purchased a new pack (as a back-up) for $60 and as yet has not been needed.
Turns out the B&S 2 cycle snow engines use the same pack.

 

[jr dragster T]

Ohh cool.

 

[Russ2251]

Lawn-Boy never built a 4 cycle engine. 4 cycle Lawn-Boy engines are B&S or Tecumseh.

 

[Jerryburger]

Gotta be honest- I think I've only seen one DuraForce in person. They must be a bit rare. The "other" lawnboy motor used in Russ' kart seemed to do pretty well for itself.
