I replaced the 350 pv motor with a 310 cylinder in my 85 250r atc. The old kit had a plv ignition so replaced with used cdi new coil and ebay cdi box. Starts up but kicks back bad. All it does is bog like its getting to much fuel. I went up and down with jets might run a little better with bigger jets but not much. Tried another carb same thing bogs. Changed stator put a rickys stator in and a new honda coil and cap same thing just bogs. Hit the throttle it jut goes boooo boooo booo wont hardly rev. Its a new air stryker carb also. I am pulling my hair out any ideas ????????????????
