Great vid, just a couple things I noticed: 1. You put the carb back on the wrong way. 2. For any beginners watching, the connecting rod just slides off the crank. Pull it towards the back of the engine after sleeve is removed, with piston close to top dead centre. Great stuff love this engine! Great to see it on fire!!

There is no right or wrong way to put the carburetor on since the vehicle this engine is going and requires the carburetor arm to be on the other side And yeah I know how to take the connecting rod out of an engine that's not a problem it's just when it hasn't been apart and probably 15 years and the varnish in the top of the wrist pin and on the back of the crankshaft is holding the connecting rod from coming off that's the only reason why there was no actual force applied to it And upon reassembly the only reason why I use the pliers because it's a little easier than trying to fumble With it I have several other rebuild videos Where I don't use any pliers at all Also the little bit of solvent that burned off is it going to hurt anything this engine got to about 260° Not even hot enough for the bearings to come out

great video learned a ton :) got that engine send to me recently in a hyper 8 car. sadly 1 of the pins of the OWB was missing, it still turns over fine, rust has found its way in, the head is scraped with a bend cooling fin, the piston has a small dent on the outer edge just above the 2 rings. The rod is still in perfect condition as is the crank, carb, clutch and pipe. Probably going to try run it 1 time and set it on a shelf when im done. :)

How did you get it out? I've got a performa I bought used, I thought it would be good to practice the whole process with. As I have a guy who looks after my race stuff. I'm too embarrassed to tell them I can't get my liner out. I've even broke the heat skink next to shim seal. But how the duck to get it out. I can't be beaten

Remove the carb obviously remove the cylinder head warm up around the block put a zip tie through the exhaust port and rotate the flywheel or push up on the bottom of the sleeve with a chopstick don't use anything metallic otherwise you will damage the sleeve do not pry on the sleeve with a flat screwdriver otherwise you will damage it do not grab it with a pair of pliers because you will put it out of round. I have several other videos explaining it. You want to get it around 200°f that will expand the block away from the sleeve and make it easy to come out. But NEVER PRIE WITH A FLAT screwdriver EVER!!

Nice vid man, I did a tear down of my O.S. 12CV and now I’m worried lol because the crank was stuck so I heated the crankcase up to 200 degrees and the crankshaft just popped out but so did the main bearing is my engine bad now?

heat it back up and drop the bearing back in. it's normal for it to fall out when the block is heated up.

@thebug4046

No water! use brake parts cleaner to clean everything and use a real oil like golden spectro 2 stroke oil to put your engines together with. Just don't add it to your fuel. .. I have video explaining everything
