Finally received the new diaphragm and it was quite easy to install after watching a couple of you tube videos.

I have given the carby a good once over and included a few photos for reference. As expected the internals were in quite good condition for their age.

Everything cleaned up nicely.

I originally set the mixture screw 1.5 turns out and the mower would not start upon being serviced. I wound the screw out an extra turn and it fired up and ran a little rough. I managed to get the engine warm whilst adjusting the mixture for smooth operation. I found the mixture screw on this carby to be very sensitive. Despite these difficulties the mower is running quite well for its age.

Just a few queries/ thoughts on this type of engine as their appears to be a few differing opinions online.

1) Best method of adjusting the mixture screws during a first start up. If I need to re-adjust I will.
2) When you turn the engine off and its warm � it�s a bugger to start because the choke closes�� any tricks to avoid this?
