'82 DL250
Engine running good until fuel valve stopped up
removed & "Kreem"'d the tank, replaced the valve
Started engine, ran for three minutes & died
Kill sw on, choke on, fuel valve reserve
Now won't start, sounds like it fires once occasionally while pulling
Plug wire to engine, pull start, good spark
Removed fuel line from carb., pull start, good flow of gas
Fuel line return to tank not plugged
I guess I need to pull the carb & check? What?
Thanks in advance.
