fuel flow rate? By OMN (Read 624 times)

[OMN]

hello, all! quick question: on the MC-54B 250, about how much fuel should be flowing into the carb while cranking the starter?

background: couldn't start it the other day, took a look at the clear fuel filter i installed close to the carb, and it was dry. hooked the mity-vac to the vacuum line running to the fuel pump, and got a couple dribbles to come up.

I took the fuel pump off, took it apart, and found a tiny blade of grass or wood splinter inside. (some may recall i found one of those in the carb a few months ago...) put the pump back together, reinstalled, and now it fires up again.

However, viewing thru the clear filter, it appears that only a trickle of gas is flowing into the carb. shouldn't that filter pretty much stay full of gas? and if i were to disconnect the line, about how much gas should i expect to see pulsing out?

thanks a million!

It should be a good little stream coming out everytime the pump pumps the fuel through. It should not be a dribble. But when it is running the fuel filter should show full when you shut it off it may not show full due to the gas draining back into the line some. It also depends on how long the hose is from the carb to the fuel filter and from the filter to the pump.
