The 182a and 182b use a different burner orifice. www.busboys sells them,and
lots of other Dometic parts. One look at the prices will get you to make the
broken ones work again.

New orifice is $12.50, brass. The orifice is different in how it mounts on
the burner box. The hole is the same in 182a and b.

The last few years of Vanagon westys used a ruby orifice.I think they are
about $45. Those will clean up with alcohol.

There are supposed to be two different orifices avaliable. A #22 and a #24
.I think #24 is for average altitiudes. The #22 for high altitudes.

Neil, give that thing a kick.
