Well I tried everything I can think of to save the chain but ended up cutting it to release the camshaft. I tried rocking the cam back and fourth given the extra slack from removing the tensioner slippers, but was still not enough for me to skip a tooth one at a time.
So then I bought a set of HF offset wrenches but the space was still too tight for the wrench head to squeeze into. I figured at this point I'd say screw it... and took a hack saw and carefully worked my way through, making sure the blade did not touch any of the sprocket teeth. A couple mins of sawing for each side of the chain link was enough to free it.
Cylinder head came out quite easily after. The pistons looks really dirty but I hope it will clean up ok. It appears that piston #3 is stuck. I tried taking the cylinder housing off by wiggling a bit and pulling, and started sliding off. Didn't put much too pressure anywhere but it's def stuck. I might take a torch to it next.
On another note, I got an ultrasonic cleaner in hopes to ease the carb cleaning process. I've seen many mixed reviews but want to try it for myself. So far I tested and am getting pretty decent results. I used about 4:1 water to SG mix at 3 cycles of 450 seconds with heat. I think it may be too diluted of a mixture so I will make more concentrated next, or pre-soak. So many different combinations to try!
