Thanks Richard for the Nut Splitter suggestion. That is not a tool I have ever
heard of, but I intend to give it a try and see if it works.
I am stuck again on this project and really need more of the excellent input I
have gotten previously. I got the exhaust riser off and was able to order a
new one. It arrived yesterday and I attempted to compare its function to the
old one. I can't convince myself that the old one is the source of the
problem. If I run water from the sink faucet into the input port where the raw
water would enter, water comes out the back (where it would go to the muffler)
in both the new and old exhaust riser. I can't see an obvious difference in
flow rate between the two. Is there a better test or is this not meaningful?
Obviously, I am going to install the new one, but I am unconvinced it is going
to fix the problem. The only thing left in the system is the muffler. I have
not heard of anyone replacing this due to blockage. I thought that tended to
occur at the exhaust riser instead, but I have found online discussions of a
blocked muffler possibility. But most of the people I see replacing their
mufflers are stainless steel ones where they begin leaking. That is not my
problem. I checked all the hoses rearward of the muffler and all look good, so
it seems my problem is either the riser or the muffler. Are there any
diagnostics I should do or just go ahead and replace the muffler at the same
time as the rest is apart and pray. Thanks- Dave
