Hi
as an old motor technician , I have just been presented with my Dads little used Mantis rotavator with a Honda GX25 engine.
I believe that it was overfilled with oil , but I cant be too sure.
When I looked at the machine , there was oil everywhere.
The fuel was cloudy with what I assume is oil , so I flushed and replaced with new.
I sampled the fuel in the oil can that was used for the fill before I started - it was clear and fresh.
The foam air cleaner was literally swimming in oil .I could wring it out in my hand
I cleaned and dried this item , along with the housing.
I removed and cleaned the spark plug , and checked the gap.
I drained and filled the oil to the correct level - all per the supplied manual.
So , the engine will only start on choke , even though I managed to get a little warmth into the engine.
I then removed the air filter and it was swimming in oil yet again after about 1 min of intermittent running.
Touch the throttle and it dies.
The exhaust is smoking quite badly.
The engine will only idle for about 15 seconds after each start
I am suspecting internal engine damage unless there is something that my basics has missed , because of the oil being emitted in volume from the carb and the oil might be creating enough of a seal to allow some form of compression at point of starting.
Can you help please.
Many thanks
Steve
