Hey there Mr Davis and Grumpy, thanks for all the tips and help it's great.
Seen as the seals aren't that expensive I have replaced both the top and bottom seals today. They actually looked pretty good, although underneath the top seal it seems like there was a little bit of oily dirt sitting on the bearing. Maybe there was a slight leak from the top seal? I cleaned it up and replaced with a new seal. I also replaced the decompressor with a new unit as it was still the original factory Victa item from the early 80's and maybe it wasn't sealing the best.
I have not touched the carby at all as a bit of a test until I get it ready to run again to see if changing the seals and decompressor will change or lower the idle speed a little as maybe it was a leak somewhere.
If it's the same then I should be pretty sure it's somewhere along the inlet where the carby sits or something wrong with the carby itself.
For the sake of a few more dollars I will grab new rubber seals for the inlet where the carby sits.
Thanks for the diagram Mr Davis yep that's exactly the same carby that i've got, it's all original as in the diagram. Nothing has been modified from factory on this one. If there is no leak anywhere in the system then I will try adding this washer there to try and bring down the idle a little bit.
Yes i've had the lawnmmower since new and I do remember many years ago the idle was a fair bit slower than what it is now. I'm just trying to get it back to the original factory idle speed.
Thanks again for all the help guys, I will get back to you again and let you know how it all goes.
Cheers!
