Hi everyone, 2000 5.0 0M012817 Carb, Non TKS.
I had the carb rebuilt a few weeks ago.... Its been running fine, but a few days ago I was hearing a hiss from the engine, and found that the gasket on the base of the carb was sucking air. The gasket that went bad was a very thin metal covered in (whatever the black stuff is) A lot of that material was gone and thats why it was sucking air. I purchased a new gasket from M/C its about 1/4 of an inch thick ( the one that was bad was 1/16 if that). When I restarted the engine, it wouldnt idle, so I turned in the idle screw and it seemed ok. But since then it starts quickly but really smokes for maybe 3-4 min. then for the rest of the day it fires perfectly, just turn the key no throttle needed.
This am, I gave it one FULL throtle, returned to neutral and it wouldn't start until I added 1/4 throttle, then started with bleck smoke.
I have checked the choke before starting it closes all the way and opens fine. One other thing...... The single needle valve adjustment on the front does bog down the engine when turning
in, but backing it off a turn or two runs smooth, but you can still turn it out 5 or more turns and it doesn't change at all.
Any idea's??
Thanks very much......Rick
