Here's the deal- I bought an 01 TTR125 that had been wrecked & sitting for 4 yrs.(for $200, by the way) Brought it home cleaned the carb(disassembled & dipped) , changed the pilot jet to a 17.5, turned the fuel screw out 1 1/2 times, replaced the choke cable, removed the snorkle and changed the spark plug. It runs like a champ when warm, idles fine & is crisp, but is a bear to start when cold. Using the choke doesn't seem to do anything. It takes lots of kicking, then begins to hit, then hits a little more and finally sputters to life. As I kick it, fuel leaks out the overflow hose. When its warm it starts 1st kick. The Main jet is stock. Any ideas what to try now? Thanks for any suggestions in advance.
