Ok....all was good for a while. I finally got her to a state where I can drive her daily to work. Acceleration and take off were great. After a few days, there started to be some lag below 3k. After a few more days of driving, it got to where it lagging below 4500 RPMs, the 5k and now it is at the point to where it will lag until 6k. After I reach 6000 RPMs, she shoots off like a rocked, but of course I have to shift and when I do, the lag or bogging down returns till 6000 RPMs is reached again. I am not sure where to start....I just had the carbs syncd and I cleaned the plugs. I just replaced the air filter and I have new wires on the way. Could it be the fuel filter causing my issues or do you think that I will have to clean my carbs again (3rd time in 6 months)? It seems the more I keep driving it, the higher I have to get the RPMs in order to get normal throttle response. also, Yes, I have been running seafoam. Please help....
