Hey guys, <br /> I've got a question. I got my 57' 18hp fastwin started and running great today. What I did notice is that when I got the motor there was a piece missing from the carb. I didn't notice until I rebiult the carb last week and started the motor. What I'm looking for is a diagram of the carb on this motor or something close. On the carb are two needle adjustments, the one on top from what I understand in the low idle adjustment and the one on the bottom is for the high idle adjustment. It's the top one that I found was missing something. It looks like there is a threaded sleeve that compresses the gromet around the needle valve that keeps it from vibrating out of adjustment. This is the part I am missing. <br /> The model number for the motor is 15020-19224. Does anyone know what the part number of this item is or have a carb diagram that I can look at?<br />Thanks
