Default need Go engine help!

Just bought a used go 3 port R and pulled it out and cant turn in over by hand the pinch at the top is tight but can get it around but at the bottom it just stop like in the pic on both sides.

Is somthing worng or is it tight? It seems like the rod is rumbing aginst the case and thats what is stoping it.

Its hard to tell but it looks like there are some pieces of aluminum or gouges on the bottom crankcase just below the rod!

The guy said he rebuilt it the bearings have 1 and 3/4 gallon and the conroad piston and sleave have 3/4 a gallon on it.

What should I do from here?

pull the piston sleev rod and crank and heat up the engine, when its hot stick the crank in and use a mooden dowel inside the crank bore to push the rear bearing in so its seated properly.
Also check the piston and sleeve for scoring or gouges around the ports.

Also If you buying an engine used and the seller says there is anything less than two to three gallons on it or its not brand new, chances are they are lieing. No one sells engines that quick unless there is something wrong with them, unless they are new.

Not true. I have a Go 5-port for sale that I put 3/4 of a gallon through. It was broke in by Pro Twister Mods and runs perfectly. I am just done with nitro. Not everyone selling nitro engines is evil!
