PES,wasn't difficult at all as long as you follow Dinqua's advice and slide the air box back. I left the throttle linkage hooked up and pulle dthe carbs out the left side. Had plenty of room to work.Had it apart, cleaned and back together in a couple of hours including beer breaks. My filters did'nt look bad but cleaned them anyway. I then as recommended by our friends on this site replaced the vac caps on the carbs as well as the spark plugs. It's now running great! I believe it was the vac caps $3.00 as the plugs looked good. But figured $5.00 for plugs what's the harm.Hope this helps.Thanks to all!!
