I've not had any that wouldn't still run, just not like I wanted them to. I've raised the port timing too high on a couple and lost to much low end torque. They still make good saws for cutting up toothpicks.
I'm over building high rpm screamers. Now I build saws strictly for torque, if it won't pull in bigger wood it's a waste of a good saw imo.
I thought thats what I done with the 290, but after I got some fuel through it. It kept gittin stronger & stronger. I was more than happy with it after it was broke in.
