That`s enough to start the bike easily with the kick starter. And yes a flooded bottom end will make your life miserable. You should be on the right track.
You have adjusted the piston on the M/C too far in. Now it`s not releasing. Back the adjuster off until you have some free play between the lever and the plunger.
My 1974 Ossa Explorer. Yes. Taken Nov. `74. Candy Apple Red by me. And it came this way! Kind of strange, looks like an MAR. It was an explorer frame and Explorer on the title.
Yellow shock or spring? At the same time your 4rt could be sagging pretty good. I was noticing that yesterday with 3 older 4rt`s next to 2 brand new 2016`s.
Sure you had a little blow by. That happened at full throttle with a cold motor. Remember you can do a 250 or a 290. The 250 Rev`s better especially at low elevations.
Just pull the cracked piece on the pipe up a little to line them back up. Put another bolt in to weld it up. By the way are you missing the spacer between that broken tab and the frame?
It is called a cold seizure. A warm engine might have survived. Remember to always check for the clunk of the slide closing completely when working on any bike.

The manual has some pretty good basic starting points for your weight. Push hard on the center of the bike (seat) and make sure the front and rear are moving together at the same time. Trials suspension is usually on the soft side.

You nicked the piston. If you remove the front pipe, you will probably be able to see the rings are now stuck. If you are lucky you might be able to clean it up. If you have aluminum stuck on the cylinder walls, use muriatic acid with a small brush. It will dissolve the stuck pieces. Keep us posted.
Dad of Two. I remember a very nice 348 do a wheelie in a section and the front forks pulled away with the tank. Incredibly the fuel line came off the carb about the same time the spark plug cap pulled off the plug. It burst into flames as the head stock broke from the rest of the frame! Was just incredible the timing that happened. That was twenty years ago. By some twist of fate I became the owner of that bike several months ago. I hope to have that bike running again for our vintage events this year!
On the Sherco side of things, my son just bent the crap out of the bash plate on his bike. Waiting for gaskets. I knew this was a problem as the frame bends easily and the plate is very soft. Looks like I`ll be re-bending the skid plate at least once a month. I`ve replaced the Top cylinder mounting bolt 4 times till I got one to hoId. I tried Loctite blue, then red and finally just got an extra long bolt and it held. Damn 18 year old kids thinking they can splatter every rock they see!
Stays in the clutch side. Years ago I made a (thin) steel plate that I attached a puller too. The plate would fit just over the crankshaft (after the flywheel was removed) and the holes would line up with the mag cover bolts.( I used longer bolts) It took 30 or so minutes to make, but it still sits in my tool box today. Made the whole job much easier.
