ok, new gasket installed.
I have also cleaned out the carby (for good measure).

I gave the cord a yank and it still feels like some compression is missing....

Anyways, I decided to give the mower a shot at starting.

I was yanking fairly evenly and had a backfire or 2. A couple of brisk pulls (i mean VERY brisk pulls) and the damn thing started running.

Now...

The machine did not sound right (not like any mower i have heard before) but it did respond well to throttle controls. Also, it seemed like the vibration was a little excessive.

I did not keep it running for long (as the neighbors would have lynched me running it at this hour). But when i switched it off, i could not get her started again...

Im hoping anyone can chime in as to what the next step is? Or is this as good as i might get the machine to be?

What exactly is there left to replace if the compression is unsatisfactory? (i think its just the bottom end crankshaft bearing?).

Also, could this low compression be contributing to the unusual sounding mower?

Any help would be appreciated. Again, as stated before, piston rings and piston seemed tight and in good nick.
