I recently had to do the piston rings on my 6.75 GTS super recycler. Once I got it all back together, it wouldn't start. I replaced the carburetor, got a new filter, and new spark plug. I have spark, compression, and fuel. I checked the armature on the fly wheel to make sure my timing was correct. Toro recommends 0.06-0.10 in gap for ignition timing, and I tried both. When I try to start, I get a pop, and that's it. No starting, just misfire. Any suggestions would be helpful. I'm close to just tearing it all apart again to make sure I didn't get the timing off on the inside gears, but I want a second opinion before I do that.
