Just purchased the mower with a blown engine. original owners ran it out of oil and wiped out the connecting rods and crank. I went ahead and installed new rings, rods, crank and of course seals and gaskets. I honed the block and before assembly. I did however assemble the block using assembly lube to ensure lubrication when first start. Anyway, getting to the point. The engine fired up fine but there is a lot of blow by through the carb. is won't rev up high and sounds like the timing is off. I tripled checked the timing marks on the crank vs the cam during assembly. I did notice the timing mark on the crank is a small arrow not a dot like the original crank. All parts were purchased from Kawasaki. Can anyone give me some advice on where to start or what to check.
