Dobrodan, the one I disconect is the one you call accelerator pump (power enrichment), this has a rod that goes from the main blade shaft to a lever that pushes the pump, that is the one I disconect.
My concern is that even I disconect it there is no odor in the exhaust of being rich or black smoke coming out, what I noticed was that the fuel economy is very bad, and looking to the spark plugs they are not to black, the only part black is in the outer part of the spark but not in the center.
Yesterday I did a compression check and I had 100 psi (very steady along the 6 cylinders), you might think that this is low but I think that being a 2600 mtr above sea level the number is ok (the reading of a baro at this altitud is 74).
Another thing I noticed was that hot it is very hard to start, the engine cranks but there is no cylinder explosions, it took me more than 5 minutes to start, I'm trying to find out what is happening, it is probably because I disconect the accelerrator pump, but not sure, if I c
onnect the accelerator pump back again and engine starts, I might think that during crank the engine might be too lean.
We need to keep in mind, that this is a 50 years old vehicle/engine, and do not know to much about the way it was mantain, and /or modifications done to it, so what I think is that there are many components in the carburetors that might be damadge or change and the full equation is not the one for the vehicle. How can I assure I have the correct components in the carburetors? (like idle jet, etc)
I realy appreciate your feed back, I will continue providing as much information as it comes and hope soon this will be sorted out.
My best regards.
