Title: CARbS!!!! the saga of the cheap riding mower
Post by: natedawg120 on August 24, 2009, 07:22:27 PM
Yeah, I am a fan of not having to walk around with my engine so I got a budget rider.  It ran good but a little rough, sat for a year surprise.  I pimped it out in the yard before I forked over the 100 beans to get it and rode it into my truck, triumphantly :icon_lol:.  Well after a good battery charge and a minute of running things go to poop.  I pull the carb bowl and gas elves have set up camp and taken a massive crap in the float bowl, :woohoo: :woohoo: :woohoo:.


Now where is that carb cleaner, or that wd40, or that anything ..... I hate moving .... but i love my garage :D

PS: Early-Mid 90s chassis, 12hp B&S I/C, 38" so not to huge but it cuts the hell out of some grass ... when it hasn't sat, i borrowed it for a summer the year before it sat and it ran great, amazing what cheap gas turns to in time  :icon_lol: :icon_lol:

Wish I could find a deal like that, I'm also tired of pushing around my mower. Oh well it's not like I don't need the exercise I guess.

ok it ran great and mowed great.  However right when i was done it was acting like it was clogged again.  Except you can watch the fuel filter empty, then it starts acting up.  Then you let it sit and the fuel filter fills back up and its fine again.  Is it possible that the fuel lines are to short for the gravity fed system?

PS:  Its not a vaccume in the tank either and i have verified a million times that gas is still flowing throuh the line to the filter easily when it is acting up.

short/long shouldn't matter on gravity fed. i'd bet there is crap in the lines, either right at the tank, or the filter is partially clogged. you've seen it slowly fill again... it should fill quickly. that means there is a problem at or before the filter for sure.

yeah that is what i am trying to figure out.  The fuel flows through the line to the filter fine when i disconnect the fuel line but this is the one piece of hose i didn't replace, just disconnected and ran a hanger through and good gas to rinse.  Did the same to the tank outlet. So there is probably one little itty bitty bit o crap in the line or tank that is buggering things up.  Its just so much fun when things that are so simple to troubleshoot keep kicking you in the balls  :icon_lol: :icon_lol:

well i found the problem but it was uber ghey.  There was a small hole/crack where the filter was sonic welded together that was letting air in but not fuel out and since the inlet to the filter was slightly less elevated that the outlet the filter would fill with air instead of gas and start to sputter when no more gas was at the paper element in the filter.  Runs great and cuts great and with another new glass car filter all is well.

Moral of the story, get a filter that looks like it wasn't made in china and if that doesn't work just chuck the filter cause you'll have to clean the carb every spring anyway
