Briggs Mod 19 Flywheel Nut

[LeadHead]

Hi All First post,long time lurker. I tried search, may be too tired-what I need is the torque spec for the nut. It has a cast iron flywheel w/out a key. I would think the setting needs to be dead on since the drive shaft bolts up to the flywheel and because it has no key, rotation force is high, can't slip/spin. Motor is on my Simplicity Mod 700 riding tractor. Had to replace org coil. Forgot to do a reverse torque ck.

Thanks Jim I forgot to add the Type No. 706035, and
Ser No. 613721 of the engine, don't know if this would change anything. I was surprised it did not have a key. I would guess if it had to slip to save the crank from twisting this would be best.

Just checking in from out of town so don't have any engine manuals to look at, but think the model 19 Briggs has an external mag. If that's the case, position of the flywheel on the crankshaft shouldn't make any difference.

Maybe someone will correct me if I'm wrong about this.

No, the Briggs Number Series Model 9 thru 23A do not have an unitized mag. The reason you do not have a key fot the flywhel is there are not any magenets. on the flywheel. The magneto magenets are on a seperate hub that goes on the crank before the flywheel does. You want the flywheel tight, no slipping, becase the engine will not run right. I just tighted the nut with a 1/2" air impact untill I feel it is tight enough. I have a complete set of Number Series B&S engines 5S thru 23. The 9 thru 23 have my coil convertion on them. I can not stand the $130.00+ cost of P/N 290880. I modify two legged coils to replace 290880.
