Should of knocked on wood .
Got car out of trailer since Nov 1 .
Dewinterized it rocker arms, newfuel ,carb back on .
Started it up great on alky even .
Started getting warm could hear pump running .
Open cap no antifreeze moving ,so shut it off .
Let it cool did some other things ,it then ran.
Pulled pump off notice i could move impeller 1/2 inch or so clockwise on shaft ,but i can't tighten or loosen set screw .Pump hot .
Anyone else know the workings of the pump ,
and cost to send back to them to update fix .
NOT KNOCKING pump at all been on car since 2000 100s possable 1000s hours .
glad to be looking at stuff now before season starts .
