Hello all. 2 problems I have that maybe someone can help. I installed my new pumper carb last week. When the bike is warm it starts first or second kick but when cold (after 2 or 3 pumps and 4 or 5 kicks) it rumbles to life for a second or two then stalls. After repeating this 4 or 5 times it will hold an idle (with encouragement) then warm up and run fine after 45 seconds or so. The second problem is the idle. The bike idles high (500-1000rpm above normal) after coming to a stop when warm every time (yes the slide is fully closed and not hanging up and correct free play on throttle cable). After I blip the throttle a couple of times it will suddenly settle and idle normally. I have no backfiring, flat spots or other indications that I am running rich or lean. I am at sea level, uncorked. Any takers on tuning these small problems out?
