Mont needs a doctor

[jimmyl]

Stood my mower up in the shed to save space - some oil must of ran into the exhaust.

took me half the lawn before I could see the neighbours again due to plumes of blue smoke - revenge for their barbecues anyway.

if this can happen to a small 4 stroke engine then imagine too much 2t oil

maybe clean exhaust front pipe out, fresh petrol - a good 2t oil - think I used to use the Castro’s fully synthetic stuff from Halfords etc and give it a good run - so long as nothing is knocking.

maybe clean carb out to make sure mixture is good - the early ones where prone to getting much in - think they work differently on pilot jet - air bled not fuel or vice a versa 

best of luck

I'm thing to bare in mind it that some.oil has a high burn rate (or something like that) so a low reving engine doesn't burn it off and will be smoky)

Remove the exhaust and see if it drains out unburnt oil. If the exhaust is partially holding oil this could be your problem. Really a photo of more of the cylinder bore would be good. Did you have the engine running when you saw the bike to buy?
