Carb identification

[wh1075 6]

I have a model 1055 with a K-241 engine.  It has issues with flooding when trying to start.  The carb is getting fuel.  The float dose not seem to be stuck open as it doesn't overflow and leak gas when sitting.  I have gone over the ignition side (new points, condenser, plug) and have strong spark.  I have double checked the timing and believe that it is correct.  Fresh gas and fuel filter make no difference.  I had the carb soaked and gone over (not rebuilt) at a local shop and installed with new gaskets and air filter with no difference.  I have adjusted it as well as I am able to from my experience but would like specific instructions.  My next step is identifying the carburetor.  It says Carter model N.   The Kohler manuals that I have reference either a Kohler built adjustable jet or a Walboro fixed jet version, neither of which seems to match this one.  I know that Carter made carburetors for many years just never saw one on a Kohler engine before.  I would like to try to rebuild this one before spending the money to get a name brand oem replacement.  Any help would be appreciated.

One thing you didn't tell us is if you've had this machine for some time and it has previously run normally, or, if this is new to you and you've not ever had it running properly.

Why do you believe it's flooding out?

 

 

[wh1075 6]

I recently bought it as a project.  I had it running very poorly for min. or two a month ago.  I have not had it running well at this point.  Had to play with choke etc just to try to keep running.  Decided to have the carb soaked.  Put back together yesterday and now I don't get even a backfire.  I believe that it is flooding since I smell gas and the spark plug is wet when I pul it out after trying to start.

What does 'gone over' mean if it doesn't mean 'rebuilt' ?  Aside from soaking it, what exactly did they do to it?

 

I don't have an answer to your question about the Carter being appropriate or not, I don't know that engine other than by the number, but I do have the 12 HP K301 which AFAIK is basically the same.

 

Have you checked compression or done a leak down test?

I have not done a leak down test at this time.  Probably a good next step.  As for the carb at the shop, I tooknl it in to be soaked and rebuilt,  when I picked it up they said they soaked and went over it.  I will look at the invoice to see what parts are listed.  I will also check with them to clarify what they did or did not do.

[Jeff-C175 7,206]

I've looked around a little to see if that engine ever used the Carter carb and didn't find anything.  The service manual only shows the Kohler and Walbro carbs.

 

But that isn't to say that it wouldn't run fine with the Carter... dunno about that!

I think Kohler engines used Carter model N carbs at least in the early to mid 60’s. I have a 1963 W.H. 753 with a Kohler K161S and a 1964 W.H. 854 with a Kohler K181S and both have original Carter model N carbs on them.        -JD-

Post a couple pic of the carb so we can see what you have.

[WHX?? 51,732]

Couple of things here. It sounds like you are not comfortable with rebuilding the carb yourself so I would suggest sending it to a carb specialist here for a look see. Not that I dont trust shops I just trust the guys here more.

Another idea might be just to get a cheapy knock off carb. and  see if you can get her to run on that. 

If you suspect it's flooding turn the mixture screws in or set per manual. Is gas coming out the intake by any chance? 

[squonk 43,778]

It's possible that you have a problem with compression. How does it sound cranking? Low compression can keep it from starting and fuel on the plug could be normal. The engine turning over will draw air through the carb which will draw fuel as well.  It seems to me if the carb was flooding that bad it would be dripping out of the air cleaner.

[WHX?? 51,732]

Kinda what I was thinking too Squonky ...a 1055 does not have ACR so they can be difficult to turn over with good compression. The short pans had an advance/retard mechanism in place of the ACR. 

[wh1075 6]

I will try to post a picture of the carb, engine etc.

[wh1075 6]

Sorry for the delay.  I was able to borrow a kit for checking compression and plan to do that this evening then post the results and some pictures.   The kit I have borrowed only does compression.   I am able to borrow a kit that does compression and leak down testing both, when my friend drings it to work with him.  I would eventually like to buy a kit for myself but haven't gotten there yet.

I have a hard time justifying purchasing a tool I may only use once or thrice in my life... especially when there are other tools I've put off acquiring because I may only use them five or ten times in my life.

But I do have a nice 'inherited' compression tester.

No leak down.

I agree.  That is another tool on the wish list which likely may never happen.  Other tools that I can use more frequently will probably come first someday.

If the carb was disassembled...where were the adjustment needles set on assembly? 

[wh1075 6]

I made sure the battery was fully charged and did the compression test.  The results were 87 psi.  I don't know if that is good or bad for this engine.  Also I am trying to add a picture of the carb.  Thanks for all the help so far.  Also the carb settings when it came back from the shop, I am not sure where they were at this point.  It didn't start so I tried to follow the manual to adjust it.  Don't believe that it was far off but can't confirm

  Next time I will be recording where it starts from.

[squonk 43,778]

Awful lot of paint on that carb for it to have been " soaked " Also that bowl gasket doesn't look new to me either. 

[pacer 3,177]

 I too have some doubts as to that carb having been around any 'soaking'

 

I havent seen any thing mentioning spark.... A wet plug could also mean its not firing - and so wouldnt run. Have you checked the ignition on it - see if the spark plug IS sparking?

[wh1075 6]

I installed a new plug and it appears to have good spark with either an inline tester or by removing the plug and letting it touch the engine cover when cranking.  Sounds like I may need to address the carburetor.   I plan to stop in to the shop and talk to the owner to see if I can determine what was and was not actually done to it.

Skip the shop, nothing worthwhile was done.  Buy a rebuild kit and you will see only a few parts to replace.

@wh1075  Just wondering, did you ever resolve this problem?
