id like to know that one to got the same problem with my 795Newbie here - Question - the primer on my 440 is leaking fuel around the pump shaft - anyone know where I can get a new one - I see in forums the name Bob Johnson but have no idea how to contact him
dang thats not what i wanted to hear..guess I'll have to break out MacGyver again!My research into this led me to switch to a tillotson on my 380 that hand an inoperable primer. My understanding is that there are no new replacements available and if you find a used one the odds of it working for long, if at all, are slim at best.
i figured it might be something like that just haven't got into mine yet but SOON..and thanks man i appreciate a little extra knowledge!You can remove the primer pump to service it. You likely need to replace the two little o rings and you're good to go.
It's a simple design and easy to work on.
I've taken plenty of the damn things off the carb and repaired them successfully.I'm not following you....... the primer can be removed but it cannot be taken apart and repaired, hence it is not serviceable. It is designed to be replaced as a complete unit but it is NLA.
If one is dealing with a non functioning primer it can be removed from the carb and cleaned out with carb cleaner. Keep plunging until it comes out clean. If it's worn so bad that it lets fuel leak then it'll obviously need replaced. I still wouldn't rule out a bad o ring letting the fuel leak out. I know you say it's leaking out the plunger, but it can be hard to tell with the way fuel crawls around things before a drop starts building up.guess I dont quite understand - mine is leaking thru the plunger into the basin that the carb sits in-how do you get the primer apart once it is off the carb?? also - does anyone have a good schematic of these flatback carbs?
