1) check the fuel petcock filter/strainer for gunk
2) try simple compression check:
	a) pull plugs and check it - good?  bad?  get a shop manual and find 
	out.  
	b) squirt a little oil into plug holes, crank to distribute, then check 
	again, get any better?  then rings gone else valves.
3) how's your floats (i beg your pardon :-) in the carbs bowls?  cracked?  
swelled?  taken on gas?  float levels ok?  jets really clean?  run better with 
choke half on?  then carb problem.  
4) some people can "read the plugs" to determine what's wrong - i can't but
clymer's shop manuals usually have pictures of plugs/conditions.

And all this advice is free free free!  Good luck.
