Grumpy and Mark thank you for this post it has been excellent.
I have an old Masport Commercial Slasher mower that was given to me with a Honda GV400 motor that was in need of a little TLC.
I opened the motor up to find the main bushes had turned within the conrod. Luckily the crank was not damaged and neither was the conrod. I tried to purchase bushes but Honda do not sell them anymore only a Conrod with the material built into the Rod. I purchased a new Conrod from Sparesman in Thailand and have started to reassemble the motor.
I followed your timing alignments for all the cogs which worked perfectly. However I am bewildered with the internal u shaped lever in that which position it should be in when putting the casing back on. I realise it is something to do with the little weights and the slide piece but not sure what it is supposed to do?
