Did you purchase from the local hobby shop or ordered online? If it were me, I'd contact customer service and see what they can do. Usually OS and their retailers stand behind their engines.

i bought it from advantage hobby.....i contacted customer service.......so far havent heard anything back.....i have an old os 10.....but washer hole is too small......and it does show it in the book that came with the engine...(the .25).

Give them a day or two to respond and then call them again. http://www.advantagehobby.com/help.p...mp;mode=update . But I wouldn't run the engine with that much slop. You could damage the engine back plate and crank.

Cheers,

thats what i was thinking.....i shut it down after i heard it rattling......thanks for your input......ed.

RE: new o.s. problem....solved
 

The endplay does seem excessive though the rattle is fairly normal for an OS LA. In fact at our field we call it the "LArattle". They run great, they just rattle.
