model #E150TRLCNM<br />I am looking up parts on the BRP website.<br /><br />-part # 0323783 Screw, plug qty. 2 SA 7<br />-part # 0317501 Screw plug, orfice qty. 2 SA 4.<br /><br />What's SA stand for, the size? How many should I expect to get with each order? two right?<br /><br />Can I get the screw plug for(# 0317501) with the orfice. The reason I ask is because this plug isn't attached to the orfice, i.e., I can remove the plug without removing the orfice.
