I GOT THE BUGGER! Endoscope worked great. I was able to insert the scope in at my riser hose junction initially to verify if old flapper was down in ypipe without taking the elbow apart. I could see the new flapper and then went down from there to see the old flapper. I then took the whole elbow and new flapper out. Using the scope to guide me and a bendable steel rod, blue tip at home depot, I fished it out. Took about an hour of fishing before i got it out as flapper was jammed in a bit.
Endoscope to phone was only $36 and worth every penny.
My port riser is cool to the touch now, however my stbd seems to be hot now as i think port side is so clear system is not balanced, something maybe plugging stbd also.
I will check to stbd now to see if maybe old flapper might be down on that side too.
What pisses me off is the shop must not have even looked down the pipe to see if old flappers were down there when they installed my new risers and manis.
