The barbed fitting came in last night so my son and I went out to the shop and went to work. We finished installing the carb and new barb fitting and hose. It all fit nicely together.
After the carb we started to clean up some of the wiring connection to see if we could get the engine to turn over. I energized the start directly with a battery charger and removed the belt. It turned over smoothly without any bearing noise so that checked out ok. I bypassed the amp meter because the needle is missing so it's toast. I cleaned up the connection on the starter relay. I turned the key and the starter hummed (at least the electrical problem is fixed) but didn't turn the motor. I decided to try and turn the motor by hand but I couldn't move it. I got out my big channel locks and finally broke the engine loose. I think the rings had rusted a little bit to the cylinder wall which is why the started only hummed and didn't turn the motor. I turned the key again and the engine finally turned over but the dipstick pushed up and I had air pushing out of the muffler. I didn't notice much sucking from the carb. I think the exhaust valve is stuck open making the engine spin very freely.
Did you see the gremlin on the side of the motor?
It started to get hot in the shop at 96 degrees and my son is getting over an ear infection so we called it a day for now.
