If it is aluminum and the hole is not over maybe 2 square inches, you can build it up with 'aluminum weld' rods and a propane torch. You would then grind/sand to blend in and paint. Aside from actual aluminum welding, this is the best repair. Like Walt said, make SURE it's not Magnesium. If it is, you'll have to replace it or use one of the non-flame methods. Look on ebay - there's always some neat Lawn-Boy stuff.

I am sure there are more complicated issues that can cause this, so you might want to wait for one of the more advanced users on here to give more detail but: I had a leaf blower that was doing this. The rewind cable was stiff and slow taking back up. It turned out that the rewind mechanism was just dirty. I cleaned it out following an exploded parts diagram to take it apart and put it back together, using a all-components-safe engine degreaser (avoiding applying it to anything with bearings) to do most of the cleaning, then spraying it off and drying it out. Lubricated a bit and put it back together and it works great now. But again, there may be a more serious issue going on. That was just my experience.

Guess I'm in the minority here, but I'd say replace it! I recently replaced a Lawn Boy 10525 that I've been using for about 10 years with a Toro 20068. I find the Toro superior in every respect. - The LB's small wheels (especially in the front) make it a rough go on my less-than-perfect lawn. The Toro is much smoother. - The LB's offset wheels make it a PITA to move across the driveway over the Belgian blocks. With the Toro, I just lift the front wheels and place them on the other side of the blocks, then lift the rear wheels and push the mower over the blocks. Not so easy with the LB. - Changing the LB from bagging to mulching to side-discharge is much more time-consuming - The LB is on its second set of rear wheels, I believe partly because the jerk of engaging the drive eventually loosens the tires from the wheels so they slip. The personal-pace system is much smoother. I was hesitant about PP but after using it a few times I think it's great. - The LB is on its third set of front wheels because they're so damn small! The last time, I replaced the 6" wheels with 7" wheels and set the front height adjustments 1/2" lower than the rear. That was somewhat of an improvement. - The LB resists being pulled backwards unless you move forward a foot or so after disengaging the drive. Not so with the Toro ... just pull it back, no problem. - The LB Duraforce engine surges from time to time. The Toro runs smooth all the time. - The Toro mulches better and doesn't clog as easily. - The Toro is smoother and quieter. The electric start and blade brake on the 20068 probably aren't necessary, but I'm glad I got them ... especially the blade brake. With the blade disengaged, the PP system can still be used to propel the mower back up the hill after I've finished mowing. The Lawn Boy engine has been reliable and still starts on the first pull. I was going to place it on the front lawn with a "Take It" sign but, now that I see there's a market for these old machines, maybe it's worth trying to sell.
