Cylinder wall has some build up. Need to clean.

Putting the 1275 in the bugeye went through the fun of wiring, had it all wired. Pulled the starter switch and the starter moved for a split second nothing else except some smoke coming from the switch.

The engine ran when I sold it to someone in my 64 sprite. He pulled it to do a swap. It sat on his garage floor since. Never outside. I bought it back for my bugeye. Put it in and it was locked up. I oiled the cylinders multiple nights with marvel but no change. I got a socket to turn the crank bolt and the engine would spin one cycle when the 2&3 cylinders got to the top it would freeze.

Popped the head of to find rust at the top of 3 cylinder. It doesn't look major and I didn't force the piston into it. This was a running engine 5 months ago. Is this something I can try cleaning? This engine is for getting the car going and then will be pulled for one that will be rebuilt and cleaned etc....

I searched here and found a couple different ideas but just want to get some good tips and things not to do! Thanks.

also looking at the picture the rust that appears to be on the cylinder wall is from the top and the oil. It wipes away with my finger and is spotless. My concern is the top ring.

I don't see why not. Take out at least that piston, do a light hone and clean clean clean the rings. That said, if I had it apart, for not a lot of money you can do a ring job and possibly bearings and have an engine that will last a lot longer. And it really won't take you any more time.

i would also want to know why the rust is there. Head gasket?

I'm guessing the head gasket was going from looking at it. There wasn't anything obvious but from the looks of the engine this hasn't been apart in a Long long time. Looks like I get to pull this engine out now then pull my other one and swap them! I may as well pull it apart and rebuild this one since I was going to rebuild one anyway.

Thanks for for the reply.

Check the brass plug that corresponds to the marks on the head gasket in the photo. It looks to be recessed from the way the headgasket is discolored/marked between cylinders 2 & 3.
Drill and pull the plug. Tap for 3/8" npt solid brass pipe plug. Insert tightly and then surface head for new gasket surface.
Common problem on 1275 heads. Address any of the plugs that have recessed.

HTH,
Mike

Thanks mike, I'll have to talk to you more when I get the point of rebuilding the engine as I don't know much about those things. I'll research it a little more.

Thank
