I had to split the tractor to work on the clutch. Now I can't seem to get it started. I have tried to bleed the fule lines. I backed off the injector nut to let air out but fuel. I backed off the by pass hose and have fuel there.
I changed out the throw out bearing last year on my Kama 554.
As I recall, there were a bunch of connections ... electrical, fuel and hydraulics plus cables etc. that had to be disconnected for the split. I did a complete thread on it here: Clutch Repair Kama 554
You might want to cruise through that thread to see if you recall any connection you need to make. I believe I took a lot of photos and posted them in there.
