I just bought a 96 carburetor version FZJ80. When I stepped on the accelerator, the car drove very slowly. When I stepped on the accelerator to the end, the maximum speed was 70KM. Cleaned the carburetor, changed the mechanical oil pump, changed the spark race, changed the carbon tank, the fire head and the fire cap with sandpaper grinding, now the car can run to 110KM per hour, but after driving 3~4KM hang into the third gear on the accelerator did not respond, the speed has been in 1000 RPM, after a period of time after flamed out and can drive normally, what is the problem? Thank you all
