tight?

okay im working on putting my briggs 5hp back together, just had it rebored to .010 oversize, guy had it cleaned and honed as well. Oiled everything up, piston, rings, more than enough in the cylinder. I got it in there but it's REALLY tight, I had to put the flywheel on all the way to rotate...

Just wondering if there is a general setting on how tight the chain should be? I have about 1/2 inch of travel up and down is that good?

my chain is tight, and i like it, i heard it was bad but didnt believe it is it bad?:confused:

is it possible to make the chain too tight? when i start it up it just wants to take off. should i loosen it up just a bit?
