Tip: Have gas mixed with the above-mentioned carbohydrates. If you have a disability of carbohydrates. or bad reeds. (spitting out the carb.)
Port a carb manifold vacuum leaks or induction motor side.
Any water around the plugs? You can kill a cylinder, if you have a leak in the exhaust ports. (despite all the claims can be burned in an engine, no water.)
Edit if you tape this old Merc, you can have traces of carbon on the top or tail rotor. So you see that you have a good spark, but it comes at the wrong time. Take a commercial tester ignition and set the strength (1 / 4 inch), so you can see the spark and turning on and see the structure of care. It is rhythmic and constant. Nobody out of step. If you are at your service, Place d ', 008th This will be the integration with the changes of N Sync CLIC.
Not take top 2 cylinder power.
You have good compression and spark, so that the injection quantity.
It affects only 2 cylinders, it is probably a question of carbohydrates, but not too quickly to remove the fuel pump - may be too weak to reach the fuel needed to lift to the upper 2 pools. To see if the pumping begins, and help your business, if so, rebuild the fuel pump again, otherwise the reconstruction of carbohydrates. Do all four - or you will be there for the other two shortly.
Are BTW, during the first two cylinders starved for fuel, they have not received oil or ......................
It was a stupid problem like 4 years ago with an engine friends. The spark in the 4-cylinder, but it was the same. I have the top and bottom of coils around and solved the problem (which I could not find). Even the sea for hours and the replacement of coin rolls and could not know why. Worth a try
