Is a Carter really that much better than a Walbro carburetor?

 

I have a Massey MF16 that has a Walbro on it and it just doesn't have that smooth steady sound to it at high rpm.

It has a good smooth idle at about 1800 to 2200, that's what the Massey owners manual says to set it at.

From Idle to 1/2 throttle it has good response and runs smooth.

From idle or 1/2 throttle to full it sputters, surges before it smooth's out and even then every so often sputters a bit. Doesn't have that smooth steady sound to it at full throttle 100% of the time.

I've done everything else I can think of, ignition, governor, mixture, leaks vacuum+head gasket, last thing was to bypass the fuel pump, it failed 2 days ago.

 

 

My other MF16 has a Carter on it and when it was running last yr it was always smooth and steady, all speeds and with different loads on the engine, it's my grass cutter. It also has the fuel pump bypassed.

I think I'm gonna try swapping carbs and see what happens.

 

 

So my Question is > Is a Carter really better than a Walbro on a Kohler 16hp engine?

I think you answered your own question. The Walbros that don't have an adjustable main jet can't be adjusted for temperature variations.

Are they the same # carburetor. #30 for a 16 hp, as far as I know. I have three 14's, one 16, one 12 and one 10. All have the adjustable high speed needle. All engines start differently and all operate different and sound different at different loads. Some of that could be because , they all have different mufflers. Maybe the mufflers are different on yours. All so sounds like it's running just a little lean on the mixture. Adjust top no load at 3600 rpms high speed jet a little rich, that some times helps the acceleration from idle to full speed. Just some thoughts, Noel.

Carter #30 is what you want.

 

Those darn Walbro carbs suck.They won't hold a low steady idle and no matter what you do they will Always try to stall out the engine on bumpy uneven ground.It's just the way they are manufactured.

 

The Walbro carbs with the Fixed main jets are the worst for boggin down on bumps and what not.When you hit a bump it chokes the jet of fuel.

 

Walbro carb parts are alot cheaper if you ever need them.Some Carter parts are a bit pricey like the main needle and float.Even though you can get aftermarket parts they will not always work the way you need them to.Especially the main needle.

here are the setting for the screws

they are for only for setup and you have to adjust the screws to make it run the best you can

 

each carb is will act different - I have found that no two carbs of the same model act the same.

It doesn't matter what brand, you want an adjustable carburetor.

 

Walbro makes great ADJUSTABLE carburetors.  They were one of the best.

 

But no fixed jet carburetor is good on an old engine.  An old engine has character, and you have to meter the fuel to match it.  The modern engines have a lot more science behind them, and they can make a fixed jet carb work.

 

My Walbro has adjustable jets, high and low, looks like this.

My Carter looks like this.

You've got the nice style Walbro.   The EPA down here doesn't let Walbro make them anymore.

I have found that it's best to adjust a carb with a tach to get it perfect.

Today I spent some time and switched carbs, removed the Walbro and installed the Carter off my other Kohler 16hp and what a difference.

Smoother, steadier, no spiting, sputtering and higher top rpm.

I took the bowel off he Walbro to see inside and it looks clean, why it don't run right I don't know.

 

All I can say for sure is My Carter works better than My Walbro.
