I have an older early 70s? Attex I'm trying to get running before I sell it. It hasn't run for a few years, the gas in the tank was old and the fuel filter was sludge. I put in new filters, cleaned tank and everything. It will run on starter fluid but won't stay running on fuel. Any suggestions? Everything seems to be clean, the carb looks to have been gone through already and is perfectly clean. Also, there are three fuel lines and I'm wondering if they are weren't possibly hooked up wrong? Thanks |

Hi, David;
It could be a number of things preventing the machine from getting fuel, but it would be a much easier guess if you can tell us what model engine and what make carburetor is on the Attex. There should be three lines to the fuel pump if it uses an external pump, and two of them will be marked with arrows. The last one is the pulse line and it goes to the crankcase.
Hope this helps

Don, thanks for the reply. I don't know a whole lot about the machine, to be honest. I just want to get it running before I sell it. It's an Attex 300. I can't find an engine model number, but I think the guy I bought it from said it was a 283cc or somethin? Anyways, the serial number for the machine is #822. It is a Tillotson carb, casting number is HR 65A. Hope this helps, any more info that you can give me would be helpful. Also, there are three fuel lines. One has the in-line fuel filter, another has a diaphram type, fuel-filter looking thing, and the other one is just a plain line with a bolt in the end of it. Where do they all get hooked up at? Thanks for the help |

Ahh, a Tillitson. It's been a long time since I tinkered with them, so maybe someone with more recent experience will add good advice. These have an internal fuel pump and get the pulse through the hole in the flange and the inslulator port. As I remember, the Tillitson HRs needed the diaphram kits replaced pretty often, and that may be what's killing yours. They use a supply line and return line to the tank, and I'm guessing the other line may just be a vent. Sorry I couldn't be more help. |

Don,
Thanks for your help. I'll look into getting a diaphram kit. A guy at the local small engine shop said something about a reed valve? Possibility or not? |

The JLO isn't a reed valve engine, but there's check valves in the body of the carb that work pretty much the same way (only with fuel instead of fuel/air mix) and maybe that's what he meant.
Good luck on the rebuild. |
