Double check the valves and put a wrench on the head bolts while your in there just to be certain.

A poor test (but somewhat helpful) of the compression can be done with the spark plug out. Put your thumb over the hole and have a buddy crank the engine. If it is good(ish) you will not have a prayer keeping your thumb over the hole. If you can there's your problem. I assume its bogging just off idle?? Adjust that carb before you get into too much else get everything as right as you can and then we can go from there with more...
