New carb now what?

[Mark siebenaler 88]

I just installed a carb on my bronco 14 from i save tractor it was really good right out of the box hardly any adjustments needed. It was running good for a couple weeks perfectly. 

Filled it with gas and mowed for awhile all fine. Then when I was getting ready to park  it started running  crappy on high and slow speed cutting out.?

Never completely died and I did see some fuel leaking out of the air cleaner.

Oh oh ... gas coming out of the carb usually means a stuck open float. Piece of crap get in there? Guessing you are running a fuel filter but even then s happens.

That was  my first thought two?

Did you install new fuel lines when fitting the carb? Especially the one from the pump to carb. The lines can degrade over time, (particularly if it’s rubber), and small particles can detach from the inside lining when you push the hose over the carb inlet pipe. Check the inlet for any sharp edges, burrs, etc. many of the ‘cheaper’ items, filters, etc can have a, “less than perfect” finish, even plastic, if edges are sharp, can damage the inside of an old rubber fuel hose.

We often assume the carb is the only issue when in fact it's a part of it. 

 

With the age of our machines and more importantly the usage of ethanol fuel we've reached the point that replacing the fuel system has become a matter of maintenance. 

 

The tank can be corroded or dirty. 

ALL new fuel lines need to be be installed. 

The fuel pump needs to be disassembled and cleaned and or rebuilt. 

The fuel filters as well of course. 

 

 

Do you still have the original carb?

 

Is it worn out?

No I just purchased it it had a throw away carb on it. I replaced fuel  lines all new and filter it's running good now.

Having personally seen at least 3 of "isave's" carbs go bad I can't give them much more credit any longer. 

They're  -  IMHO  -  better than a cheapo but still not very long lived and not repairable like an OE Kohler. 

 

If you intend to keep that Bronco 14 and use it for real work more than a couple years you'd be money ahead and stress reduced to casually look for a good Kohler  #30.

Why aren’t they repairable?

Most of the Kohler carbs have a "cup" of sorts around the top of the upper throttle shaft. That cup holds a particular bushing that moves the contact point from the worn place of the upper carb body to a new fresh surface on the throttle shaft. 

None of the aftermarket carbs I've seen... yet... have that recess.
