Bought a used unit and I need help on this one. Poor weak low rpm idle with a smoky exhaust. Add a little choke no smoke and strong idle.
The spark plug is shiny black on the electrode and not grey. Their is zero no oily residue at the muffler exhaust tip which is dry with black carbon.
Valves have been adjusted intake/exhaust .004/.005 Engine starts on 1st pull.
Oil changed.
There was debris in the fuel tank and in the process of installing a B&S shorty 75micron inline filter. Not much room on the LCT. Used an oil extractor to remove fuel and debris. Wiped out with a paper towel.
I drained the carb and have not yet removed the carb’s bowl. Will do after installing the inline filter. I really don’t want to remove the fuel tank or rebuild the carb.
Will do Seafoam and 5 minutes idles for the next week.
What is the cause of the low idle and need for choke? Any suggestions moving forward?
