RE: engine proplem please help
i now this shop they dont now any thing and they will take 30 $ only for opining the engine
and i now the best shop in the uae but i want to fix it by myself |
RE: engine proplem please help
Heat the engine cylinder. This will loosen your piston. (when hot, the liner expands more than the piston)
If your mixture is too rich, the oil is thinned. because of the piston pinch in a new engine, this will stick the piston in top dead center. This is normal. Use more oil for running in, and do not flood the engine. Heating the engine before starting also helps. A tight piston is the sign of a good engine. You should respect it. The engine will give better power, and last longer. |

<div align="center">thank u man..... so i should lean it a bit
and how can i heat the cylinder without damaging it and the problem was from the oil after all and thank u so much </div> |
RE: engine proplem please help
Are you sure there's pinch?....He's talking about a Baja 5B engine...that's a gasoline engine with a piston ring...shouldn't be any pinch.
Piston should never get stuck unless it is so flooded the combustion chamber is full of fuel and the piston won't move any further. In that case, take the sparkplug out and crank it over a few times. If it's really stuck.....remove the exhaust and look at side of piston through exhaust port. Do you see any damage?...Like heavy scoring? If so, it has to come apart for repairs. If the piston really is stuck due to heat, then be careful about heating the cylinder head.....there's gasoline around, so don't use an open flame. Try a hair drier. I can only imagine a piston being stuck this way if the engine was running way too lean and got very hot and after shut-down, teh ring/piston somehow stuck to teh cylinder wall.....but the whole thing sounds unlikely to me. |

RE: engine proplem please help
Yes. And if there is scorring when you look through the exhaust, perhaps the wrong type oil was mixed with the gasoline? That could also be a reason if you're sure it wasn't running lean.

RE: engine proplem please help
thanks man i did what u told me i heated the cylinder it works
you saved my wallet from paying 300$ lol man u rooooock |
RE: engine proplem please help

RE: engine proplem please help
Well Big Dog.....we can't win them all......LOL.

RE: engine proplem please help
yeah it happens.
i'm the king of bringin back things from the dead. the wd-40 actually helps free up stuck rings and really nothing else. it's just for freeing purposes upon start up and anything after that is up to the oil in the fuel. |
