No markings on the case so that must have been replaced as well.
Engine still has some pinch left in the sleeve when I disassembled it to take a look.
dub sent me a reg backplate to loose the backplate mount and a new spinner works just fine.
This engine has the racing engine bolt pattern ( same as a nelson q40 ) unlike the current sport jetts, so it must be from
racing stock
, Sure screams when I ran it the other night.
Do sport jetts ever wear out? I have seen lots of posts as to the inability to wear one out, just wondering.
Thanks again Bob for the info, its appreciated
