The WR is very difficult to get started when hot. When cold, first start of the day, it will start on the first or second kick. But when the engine is warmed, I need to give it several twists of the throttle and on average, about 20-30 kicks. Once started it runs great. It is not the spark plug. I assume it is carb related. Anyone know where the problem likely is? Is it something that I can fix without removing the carb?
