Here is what I have a 2001 trx 90 with a115cc kit in it, 200x kehlin carb unifilter, & fmf power core4 pipe. Before winter it had a slight hestation at 1/4 throttle we took apart & cleaned out real good & wanted to change pilot but no one had any. My son had to go back to school & it sat all winter long on work bench not put together, so I not being a great mechanic put it back & have had nothing but problems.
Here is what i have in carb, & my engine builder retook apart carb to make sure I didnt do anything wrong. main jet 108, pilot 38, needle in the middle, fuel screw 2 1/2 turns. Here is what it is doing:
Idles ok liittle high then revs down, 0-1/4 throttle ok 1/4-1/2 boggs out looses power, 1/2 - full wants to die. Full choke sounds good but revs real fast. I have tried different mains of 100 105 108 112 120 130, & everything seems the same. I didnt do anything but put back together. Checked for air leak in carb boot, sprayed soapy water over engine & carb to see air leaks & checked air into gas cap. I have no freakin clue. Oh & plug seemed a little wet not much though, PLEASE help. I know there are a lot of good brains on here,
Thanx Ken
