working great on 901 2nd try, haah first was straw was good but instantly flooded cuz the fill moved got stuck,, i twist my carts all the time... i guess thats a bad habit lol,
so the spring get 2 from a pen cut in half then unwound at bottom so it stays in cart,, then took half the polyfill and made a lil ball and twisted it into the spring so it cant come out,, so now the fill part is a lil harder but not really,,
took my dental flos pix,, its plastic and pointed on end,, slide that in the side of fill push it over a lil and drip on to the plastic pic and it will drip right into the cart 10 - 12 drops and shes full and the filler isnt coming out..
I like it now,,, thx everyone..
