7,000 miles since March last year. I decided to vacuum the gasifier, Leitinger style. I’ve only done that once, in the fall. I have no other way of emptying the dump area and the coarse sandy part of the ash likes to accumulate as a bottom sediment.
While doing this I discovered my restriction looked funny. Kind of oval shaped. When I touched it, it was loose and about to fall down. It’s a bearing racer and its flange sat on a spacer. The flange is now burned away.
I put a new bearing racer restriction in. 4.5" ID this time. The old one was 4" ID (before it became oval )
What’s funny is that the flaky side of the restriction is the outside. Inside is smoth as new ???
No damage to the thin 1/16 ss protective shields around the nozzle area.
