After having this on my list for over a year, I finally got around to it. For the last few months, since I put the new engine in, about every 10-20 miles I have been having to clean the idle jets.
When I pulled the fuel lines off, there was a lot of black gooey crud around the fuel drain fittings and a small amount of fine rust "silt". There were no big chunks of rust, but there was a fine coat of rust all over the inside walls.
I had a radiator shop boil it and I then treated it with the Por-15 metal prep and tank sealer. We sprayed the exterior with their black chassis paint... looks like NOS. This was a very easy project.
I am amazed at the difference. It is so pronounced, I feel like it is more of an "upgrade" than a "repair".
The motor is totally smooth from idle, to light acceleration thru out it's rpm's. Sustained revs in the lower range do not miss a beat. After a 100 miles the idle circuit is still totally smooth. I wish I had done this a year ago.
So if you've been thinking about it...
