Weird motor issue

[KnappAttack]

So what did we learn from all this?

1. the new, albeit broken & humbled steveO, can clearly & calmly state his knowledge without picking a fight
2. my OCD with sleds should not be laughed at, but rather revered, as i may have the cleanest valves out there
3. FLEECER has 300 hp & a gun which would make him a great Seargent of Arms of the newly sanctioned TYOCD Clan
4. start your sleds & dream boys........even at 90 degrees in your SPEEDO.......tell your wife it's life or death........for your motor (or engine's) health

I'll park mine in a dry place and just let it sit. Has not been an issue for me. Oil on, or I should say drained back from the engine (rings and cylinders) along with rusted valves is very real, but they always come back to life it seems and run well the next season after having some miles put on.

Some say more harm is done buy running them than good, I know how much water (condensation) is put into them without running them for some time to get that condensation out of them with temp and time, which you can't get just running it for 10-15 min.

Aaaagreeeeeddd knappAttack.

The reason for my original response is in every relation to yours. The title to this thread should be "Am I over thinking this". Reason being is because no one here has tore down the ops engine and can come up with everything under the sun of what may have cause this engine to be easily turned over by hand but getting back to the basics of everything is... Just fire them up and ride them. We've been doing this for years with engines and they work great. I grew up in a junk yard and hung big breaker bars from harmonic balancer a with cinder blocks on the end of it, dripping in trans fluid into the cylinders to break the engine free. After a few weeks, wall in there and the cinder blocks are laying on the ground. Spray some gas down the carb.... Boom, we now have a running,operable fork lift that the family buisness couldn't get running. Lol smokes a little bit but it's easier lifting a pallet of batteries then loading batteries by hand. Obviously were talking something that had a intake manifold filled with water that someone scrapped vs a snowmobile that sat for a summer. But non the less, it probably was a fuzz easier to turn by hand. And it is understandable, on the flip side. We shouldn't make it a point to scare people and give them anxiety for them not running there sleds over the summer. Winters here, change the oil and let's ride

Fair enough, as for me I start mine every month or two, prolly not as much as OCD but I usually need too make sure the TACH IS WORKING CORRECTLY

I'm not going to lie, I'm a little kid when it comes to snowmobiles. I start mine, rev it up, ride it around the lawn. The whole nine. Take stuff apart and put it back together for no reason too lol

I would think one of the key observations from the OP is the backfire. That would make me think a valve hung up for a bit.
