Righto I think things are looking up!
Last night I did the following:
1) Replaced the two carby gaskets and the air filter gasket.
2) Replaced the carby bowl washer as it was dodgy with a proper fuel proof washer
3) Re-installed the throttle linkage making sure the paddle shaft shaft was turned clockwise and joined to the throttle control when at full throttle.
4) Re-installed the choke rod to ensure and ensure the choke was fully closed when in the choke position.
5) Installed my new fuel cap and spacer. This spacer didn�t fall into the tank so that was a plus!
Result:
Mower started very easily and ran at full speed really well with no hunting at all. It kept running after stopping and starting several time with no hunting at full speed. You have to get used to the full speed position setting.
The mower idled reasonably well, however at idle it sort of hunts ever so slightly. You can see the governor arm moving slighting however I want to understand if this is normal feature at idle speed. The idle is quite smooth and never stalls with no coughing or spluttering from the engine.
Would adjusting the carby screw we spoke about earlier enable the finishing touches to be put on this mower?
When I first adjusted the screw it was in tight. What adjustment do you suggest if applicable?
The funny thing is the guy that gave me this mower said the local shop tried to fix it but couldn�t. I do like a challenge.
