What is garbage? Your comment? What exactly is garbage? the fact that the accelerator was leaking due to too much fuel pressure and I put a regulator on and shared my experience with other people in the same boat? Be a little more constructive than that. Not a lot of people are familiar with the old mechanical fuel pumps and even more don't realize they don't hold a steady fuel pressure well and the pressure can change with wear and tear. Hope your life gets better.
I am having the same issue, after the rebuild the accelerator pump was leaking. Rebuilt it because of accelerator pump was leaking gas from the top of it. So you are saying that the fuel pressure regulator inside of the fuel pump has went bad, causing too much pressure at the float?
@@geraldcrutchfield1451 seems that the mechanical is pumping way too much fuel. Put the regulator on it and it should be good. Shouldn't have to replace the mechanical. These carbs only require 4 psi to work efficiently.
@@geraldcrutchfield1451 In my case that is what it was. I didn't do anything different when I rebuilt the carb but it started leaking from the accelerator pump. I took the carb off several times thinking my float was too high and causing it not to cut the fuel flow off in time before someone in a forum told me they had the same issue and fixed it by putting in a fuel pressure regulator. Fixed the problem. What they said is the old mechanical pumps can't be trusted to send constant fuel and aren't regulated by themselves and can change after time.
Russell O'Dell any idea what caused it? Before the rebuild you didn't need the regulator right? I came from the other video of it leaking out of the top of the accelerator pump. I think I read somewhere that the M4MC should be good around 4lbs of pressure. Anything higher is no good.
plz let me know too. I rebuilt mine found out I didn't have enough pressure. I replaced fuel filter and fuel pump. now it's leaking out of excel orator pump and all over. I cleaned all the surfaces really good. I used 2 cans of carb cleaner and a tooth brush n rag.
Find out how much fuel pressure your new pump is putting out. In my case, the mechanical pump was pushing out more pressure than the carb could handle. This carb is made to only handle around 6lbs of fuel pressure. I had to install a fuel pressure regulator between the fuel pump and carb and adjusted it down to around 5lbs and it hasn't leaked since. If you have rebuilt yours and you have double and triple checked everything to make sure you haven't missed any old gaskets or hung the float incorrectly then i would suggest trying this.
from what others have told me and what i have gathered from the web, mechanical pumps don't ussually keep a stable fuel pressure and most recommend a pressure regulator inline with them. I'm not sure on this though but in my case it was true.
+stephen long I ended up putting a fuel pressure regulator between the pump and the carb. I got a cheap one off of amazon and a guage. It solved the issue. I believe anything over 6lbs of pressure will make it leak from there but i'm not sure of that number. I believe 6lbs is the max for that carb. I hear the old pumps can pump at unreliable pressures and its best to put a regulator in anyways.
stephen long Check to make sure you got all the old spacers out and all the old gasket out of there. Triple check to make sure everything was reassembled correctly. It kind of threw me off that mind started doing it after a rebuild too because it wasn't doing it before it and i did everything the way it was supposed to be done. I even thought the float was going too high and not stopping the reservoir from stopping due to an adjustment i must have made by accident but it wasn't. i think they are just really sensitive when it comes to fuel pressure.
