I got this from my sister after my brother in law passed away. It had set for several years. Turned over very hard but got it started. Carb needle valve was stuck and filled oil with gas and smoked like crazy. Fixed that, now it tries to turn over but locks up during the stroke. Took the plug out it turns over fine. Replaced battery, starter and solenoid, still same thing. Tried putting some oil in cylinder wall, did not work.It is a B&S model287707, Type 1224-E1, code 97100620.Could it be a bent rod and if so how do I check it? Thanks so much for your help.

You need to adjust the overhead valves,I had the same problem with my sons mower. My sons actually vibrated the crankcase bolts loose to the point the engine locked up and cracked the crankcase. JB welded it and got it running again.

The cylinder is full of oil, and is locking up due to hydraulic lock. Remove plug, and crank engine until no more oil issues from plug hole. Fit NEW spark plug, and re-start.
