Man i hate that i have one that is only 5 years old this means i have three more years on it before the engine case blowes out. LOL I have a case if you need one let me know
Try looking on e-bay thay have some good deals on there sometimes. I have got some flexshafts from there and got a good deal on them. Just watch the shipping prices on there.
What is so bad wrong with the K&B engines I have been running two of them for three years and have never had a lot of trouble with them Any engine will give you trouble if you dont take the time to keep it up and service it like it needs to be
