I been working on this thing for like 2 months now and it will not run right, is very smokey, and has a pretty loud tap that i think is in the bottom end. Not sure how much the parts are but i will put the time into it if they are pretty cheap. Im not very experienced but going off how the plug looks and the oil on top of the piston i am getting a whole lot of oil coming in from somewhere, not sure if it can come from the valves or if the rings are just shot, my cheap scope cant really see the walls of the cylinder too well.

Pulled my '86 Moto4 out of shed where it sat for 20 years. I knew it smoked. checked it over a little put in gas and it fired right up!!
Drove about 100 yards, ran about half throttle wouldn't idle. Put on somenew parts, jug/piston and rings, carb and valve seals.
'went together ok, tuned it over by hand about 6 revs whick went well. Hit the starter it fired for about 6 revs and quit. tried it again fired once and then th sound of something slipping like maybe chain slipping over spoket.
Took cover off to watch cam sproket, hit starter again, heard same noise and the cam sproket was not turning but jumping a bit. Chain was still tight. You will probably tell me I need to split the lower case but hoping there mightbe something else.
I don't fully understand the chain tightener, the plunger only moves about 1/4 inch, should it move much more than that when off the motor and compressing it by hand?
Thanks for any thoughts.

So i bought a chinese carb and in messing around still trying to get it to run right i figured id pull the spark plug to see if it was running rich, well it was definitely but also i have a nasty mark on the strap (i think thats what its called) that looks like the piston has been smacking it. I never actually pulled the plug because i had it running for a second on starter fluid when i first bought it and was just stupid and figured whatever was in there was good. The part number on it is DPR7EA, which is similar to what is called out for in the manual but i assume the little bit off that the code is means it must be a bit longer or something. Unless the plugs are made like this, but i can pretty easily see that metal has been pushed away from the area of impact. What are the odds that my piston is trashed now you think? It does still run just not well due to carb issues but thats a whole other problem.
Actually i just took a second to google both plugs and it says the reach is the same its just different resistor values and gap size, so maybe the bigger gap is why its hitting. Either way the actual one for it is on the way and i hope it just didnt do to much damage. Wish i woulda just went over the whole thing like i normally do with this stuff.

Picked up a 86’ LT 185 for $10 in trade value(my items only cost me $10)
recoil only , I pull the recoil and it won’t move , so I took it off , I can spin the crank there one full turn left then it locks up , and one full turn back to the right and it locks up
pulled the plug , the piston is moving up n down , both valves are moving(pulled the caps)
pulled the clutch off , oil pump gear , and it still locks up after one turn
any ideas or where to go from here would be greatly appreciated
im a 2 stroke guy so this all is new to me
thank you in advance y’all
