Just had the top end of engine apart.
Now when the MSD cap is on( has the two spring loaded dogleg deals on it to fasten it…it’s not tight, can move the cap around with the legs out.
Is there some sweet spot, register I am not seeing. Getting an intermittent loud backfire, thinking this cap not seating correctly has something to do with it.
Don’t think it should move around at all. Has the standard push lock type non HEI cap on it.
