Heck, if a 110v starter works for YOU, who'm I to say no? Fact is, it's no good to me- I just finished ripping the 110v starter OFF the old 6hp Tec snowblower motor I just got.
And Mike- I've never accidently welded bearings or seen it done, but I will say this: I guarantee that bearings won't survive unscathed on some level if one were to include them in a welding circuit. For example- If one were to put the work clamp on the axle shaft, then weld, say, the pillow block housing, the bearing WILL get hurt. The current would have to pass right through the bearing, and with random and innefficient electrical gaps and conductivity, the arc would jump any gaps and cause damage. I'm not saying they'd melt solid, just damage. On the other hand if you put the clamp on the kart frame, and weld in the pillow block housing, no damage will likely be done, as the power is not forced to travel through the bearing.
And- My GX340 cold starts wonderfully, thank you, Honda!!!
