Bad coil? No.
Air in pump? No.
It strains going up? When you say it drops too quickly, you mean when you hit the lower button? Or does it creep down?
There is an adjustment screw to adjust drop speed. There is another screw to adjust pump pressure. I do not advise even attempting to adjust pump pressure without a gauge. The E-60 is capable of 6000 PSI, and at around 3500 PSI you can blow the top cap off the unit.
Early models were plagued with problems, and I see them selling like crazy on eBay. They used a rubber packing on the small lift ram. This is severely affected by alcohol. America's Body Company used to add 4 oz. of Methanol to all the units they sold, which ate the packing. The smaller 1.25" lift cylinder needed 2500 PSI to lift the blade. Meyer upgraded it to a 1.75" cylinder, with woven packing, and dropped the pump pressure to 2000 PSI. The seat of the pump relief valve often came loose, allowing the pressure to go too high, resulting in the top cap blowing off the unit.
If you still have a single terminal motor, it too could be the problem. It could be tired, and not reaching the proper RPM. It could also have a bad ground, and not be reaching the proper RPM. To upgrade the motor to a 2 lug, you also need the motor mounting plate.
If the unit is creeping down, it could be the lift ram packing cup, or the A valve O rings, or the A valve itself. If it just drops too fast, you can adjust that.
What I find is often people don't know where to add fluid to these units, and just start unscrewing things, and in the process, they change adjustments. It could just be a simple 1/2 turn of an adjusting screw that will solve your problem, but without a gauge, you can't do it properly. Your pump could be worn to the point of needing replacement, but again, without a gauge, you can't know that for sure.
