HI all, I was recently given a Kirby Tecumseh Model HK30 off from a rescued Scott Bonner mower. It seemed like a good project as the motor turned over easily with reasonable compression. Unfortunately as it seemed to backfire rather severely I guessed that it must be out of time. In hind sight it may have been something else. With these motors you need to remove the head and flywheel to adjust the timing and while removing the fly wheel I broke the end off from the crankshaft. (Didn't think I hit it that hard, by the crystalline appearance of the break I guess it was a fault in the metal or metal fatigue). There is about half a thread left on the crankshaft.
Regardless it has made it a little bigger project then what I wanted to take on in a reward effort ratio.
If any one out there wants it they are free to collect it in West Australia or I am happy to drop the oil out of it put the pieces in a box and drop it at the post office.
It had a compression reading of 70psi before I pulled the head off, good regular spark. There are no obvious scratches or marks in the cylinder wall and I cannot feel any play in the piston. The cylinder head appears in good condition. The valves do not have any obvious marks on them but are badly carboned which may have been the problem. The only thing I am aware of that is missing is the fuel tank and the air cleaner. I want to keep the drive pulley shown in the photo.
Let me know if you are interested.
If I can get a large enough hammer it will run for awhile just trying to get away from me
