ROTARY LAWN MOWER - 917.378430
Hi Gurus,
I am trying to service my old trusted lawn lower but have following issues:
It is running at 2200-2300 (tachometer) and I would like be around 2900 rpm. I have changed governor arm to the right ( > 90 degrees) by 1/8 increments but it still run at 2200 -2300 rpm. I made sure the arm Torx screw is tight. When I move arm while running it revs at higher speed. I What I am doing wrong?
I have to prime more than 10 to get it started, once started it runs fine, meaning fuel is flowing as needed. I replaced the primer bulb and also rebuild the Tecumseh carb last year, fuel line looked fine therefore I did not replace it! What to check next?
It is leaking a little oil from oil tube. To make sure it is not from oil sel, I had removed the flywheel, luckily no oil leak there but I found a piece of graphite about the size of flywheel key on the floor. It si smooth on one. I am of opinion that it is a part of lawn mower but can not figure out where it belongs!!!
It has also started making some rattling noise, please see clip. Is it from engine block. Please help in identifying.
