Its been a while since I have worked on carbs. Well I got a great deal on a 300ex so I picked it up. It ran good when I got it, but it was already warmed up. Couple days go past and I want to give it a good going through. Started it to warm up a little, it wouldnt idle, adjusted idle up till it idled smooth(wasn't idling high). Then when it warmed up it was racing at an idle. Adjusted it down then it was sporatic. Changed oil, pulled air filter(kn), then I notice the inlet tube to carb was wet. Ok, smelled it, it was gas, pulled it all apart and took carb apart. Accel pump wrked fine not gummed up. Pulled jets to see size, it was running a 38 and a 130. It has slip on and airfilter with no lid( I have lid to put on). Looked it up nd that's close to what's recommended. Checked a/f and it was all the way in. Screwed it 2 1/4 out and put all back together. Motor was slightly warm and it started and idled great. Ran better to( outruns my friends stock one with 100+lbs extra). Well went out today and started it. It wouldn't idle till it was warmed up a little. Is this typical or what should I try next. Oh, and spark plug was hand tight before and I tightened. Sorry for novel. Motor background, no blue smoke, slight blck smoke every once in a while(rich). Are these things so cold natured it takes them about 3minutes to run properly, I don't remember my warrior being like that.
