Thank you Gadge for your reply.
The factory number is 59 according to the code reference.
I thought the partly sheered flywheel key would have fixed the rough running issue, but it didn't. Machine still has the wobbles when running, but the motor seems to be rubber mounted on the frame bolts, indicating this was an expected standard.
The primer leaked fuel when I first picked it up from my customer and put fuel in it, but this issue has since stopped after the initial carbie clean.
There appears to be very little compression when turning the blade by hand and, with compression test result being so low, after 3 pulls, only registering 35 psi, was a poor result.
Not sure where to turn, except compression rings, or lack thereof.
There was a lot of oil gunk built up at both ends of the drive-shaft with my thought being incorrect timing adding pressure to both magneto and pto seals due to sheering of flywheel pin.
Photo of oily gunk build-up on top of motor (under magneto) is now attached here for reference....

Sorry, no photos of oily gunk build-up from bottom end as main concern was initially to get it going.
I am starting to have a total dislike for these "self-controlled" no-throttle no-choke versions, but they seem to be coming more popular mowers.
Head will be taken off tomorrow for a look, but I'm at a loss. At 16 years, compression may be an unexpected issue, but may be the ultimate solution????
Appreciate your help, assistance and advice.
Thank you.
Daryl
