Will a shop manual for a '98 Yamaha F50TLRW tell me how to adjust the idle? The previous owner had let the engine set and it varnished up the carbs. He said he had the carbs worked on, but the idle is not right. When I go fishing, I have to increase the idle in order to get the engine started. After it warms up, I take the cowling off and adjust the idle back. I tried to adjust it today as best I can (just by ear) and hope it will do for my fishing trip tomorrow, but I need the proper steps so I will have it done right. Any help appreciated. Thanks everyone. Larry
