Good morning, I was wondering if anyone could tell me what the 4/6 cylinders have for casting numbers? I recently picked up a 4/6 but the cylinders are bare cast and not black. Any information is appreciated.
-
The ones I have say 440/2A like Invader jugs. No special numbers on them to indicate that they are 4/6 jugs. The only odd one has a "3" cast into it just behind the "440/2A 3". The humps on the intake side are the most obvious thing.

Thanks, you would happen to have a good photo showing that difference?

Never mind I found one. Thanks

Looks like someone has swapped on a set of Invader jugs, so I will likely be in the market for some 4/6 cylinders in the near future.

I have seen that swap a few times...The 4/6 cylinders like to cold seize. They also are a 1-year only part so are more difficult to find.

Another thing to know about the 4/6 is the piston and rings. Invader piston # for 1980 is 13001-3007 and a ring number of 13008-3001. The 4/6 has a piston # of 13001-3011 and a ring number of 13008-3008. The difference in the piston is the 4/6 is coated and the ring gap locating pin is positioned to put the ring gap safely along the side of the jug. The 13001-3007 used in a 4/6 jug puts the gap on the intake bridge. Many have run this combination but I wonder how long until the rings wear enough to catch an edge?? I have measured the rings for both and they are the same dimension's but the 4/6 ring is coated to assist with break in. As I finish this reply I am questioning if I remember the pin location details correctly??
