Rebuilt carb on '04 RMZ-250 and it won't start
Posted November 04, 2012 - 04:43 PM
Now, it won't start.. I screwed around with the idle speed djustment screw and wonder if that is my problem? I attempted to adjust the idle UP, hoping to just get it running.
I also re-adjusted the idle-air (2 1/4 turns). The previous owner put an aftermaket adjuster screw in.
Any suggestions?? I have read all of the comments about valve adjustment and plan to do that. But I want to get it at least running again first.
BTW- I've been kicking it over as suggested here(in neutral). I've also tried pop starting it in 2nd

I noticed that the hot start plunger, wher it screws into the carb was a little goofy. The boot appeared to be poped off of the part that screws into the carb. I fixed and also adjusted the cable so that I was sure the plunger is all the way in.
I adjusted the idle setting so that the screw just touched the throttle cam, then I gave it about 1 more full turn, so that it holds the throttle only a little open. *** is this correct??? ****
NOW: If i kick it using the recommended technique, I can get it to fire and run for 5 seconds, then it will die. I found that a quick twist of the throttle while kicking will get it to bump over.
Thing is - I don't know if its carb or valves.. am I wasting my time messing with the carb and should I jump righ into the valve clearance check?

My valves are WAY out: both intakes at 0, one exhaust at 0.024 the other at 0.014.
Are these kind of numbers normal ?? Those exhaust numbers seem crazy loose.
