I know may people recommend a squeeze bulb, in line to make bleeding the system simpler, and it likely works well. But, I believe I read somewhere here that thye may not be up to code, so to speak, for use inside an engine compartment. This may put you at some risk, if ever there was a fire / insurance
Most squeeze bulbs I have seen are for outboard
engine use, and I believe has some warning to that effect. To each his own.
For the few times I have to bleed the system, the manual lift pump works fine. If it doesn't seem to work, lift your decompression levers, turn the engine over manual one crank, and try again, as the cam may not be in the correct position / stroke. As well, it is deceiving as the lift pump does nothing throughout about the first 3/4 of it's stroke, and then pumps during the last little push on the lever.
