Slow motion

It may happen that somewhere is entering the carburetor.

Thanks for the answers. It has two pairs of beautiful, instead of being independent, and it is not carburation. The feeding system is through injectors. The spark plugs are changed recently. Greetings

Well, you have to focus on that cylinder that works halfway, this can be basically due to lack of fuel, due to lack of spark or a bad compression, you can send to try your coil to rule Tests, those are more less the steps to follow.

Thank you. Why a bad compression?, Combustion chamber? Valve seat? I will have to prepare the pocket ...

Bad compression is basically due to two factors or rings or valves, if it is a valve first, it is tested with a regulation, if it is already adjustment, but eye because the status of the cylinder head is very important, if the compression is wrong, it will not be correct, first Czech and then, depending on the result you take out the cylinder head to see surface and change packaging, it is more normal that this is to the failure more than rings or valve
