Hi there, my ancient machine (engine) starts to cough once running at operating temp. Only way to keep from stalling is to put choke on 1/2 to full. Engine seems to run better cold. Although after running for 5 or ten mins idle speed starts to fluctuate greatly? Just started engine from cold… it fired up then promptly quit had to restart which has been usual lately especially when temp is +5 deg celsius current temp or colder ever since carb was rebuilt with new jets etc last fall at Honda dealer. New honda carb not being made for my machine. Did check my batt got 12+ volts. Have replaced fuel pump in the past, could it be causing my problem? Read about cut out relay?? sounds complicated!!!! Also had CDI replaced about 2 or 3 yrs ago. Can feel pulse in pump. is there an easy way to check it? Any help appreciated!
Frustrated with the old horse.
