I'm after a new o'ring for the 4ac Dizzy. It's leaking oil like crazy, is it a special one ? And where is the best place to find one ? Thanks in advance for the help. 

Nothing special. Just go to your local nuts and bolts store and it'll likely be a 10c fix!

Thanks for the quick reply I grabbed one from the local shop but now the issue is it won't start. It cranks then will pop but won't actually start. Am I doing something wrong ? 

Ok finally solved the problem, it now starts and runs. Still not too sure about the o'ring as it wasn't the best fit but I'll see how it goes. Would be awesome if someone had a part number. 

Just get one from Toyota. And make sure you put the engine to TDC before you pull it out again 

Ok thanks. I'll see if I can get one from the local Toyota dealer.
