Briggs engine but not a Cub Cadet
I have a 24 hp v twin Intek that is driving me CRAZY. It is on a Huskee tractor that was given to me. Model 407577 0292 E1. It has the single barrel Nikki carb with no fuel adjustment screws. The tractor looks like it was taken care of but the engine runs like crap. When I first started it it wanted to lope at idle so I checked the governor adjustment which was ok. Since then I have checked everything there is to check--- valve adjustment, compression and leakdown tests, ignition spark, new plugs, checked the flywheel key, new fuel pump, fuel filter, and checked for intake leaks with my propane wand. At some point it stopped the loping but still is not running smooth. I removed the carb, got a new seal and cleaned the carb out. It seems to be running lean because when I pull the choke partly out it seems to smooth out. I am at my witts end. I am about ready to find an old style carb off a Kohler or Briggs and put on it. Im sure that would be a challenge.
I would appreciate any input on this problem. Thank you in advance, Jim The reason I have done so much on this is because it is going to be my tractor to mulch leaves with and keep my Cubs clean. :biggrin2: |
Is the fuel flowing freely from the tank?
|
Yes it is. I even drained the tank and put in new fuel. Even put a new "o" ring on the dipstick tube because the pump runs off of crankcase pulses.

It uh.... it doesn't hurt them to get leaves on them. They were actually built to do that kind of stuff..... |
how does it run when mowing? any signs of a leaking head gasket or intake manifold?
|
Welcome to the EPA world. They are jetted so lean that they barely run at idle. The fact that it runs better with a little choke answers the question. I looked at the carb and don't even see any adjustment possibilities. I guess you learn to live with it or try to find the slow speed jet and take a set of small hobby drills and try to open up the jet a little. Wish I had a better answer.

No J-mech, I did not buy another tractor to do my leaves. It says in the very first of my original post that it was given to me. What difference does it make if I use an old off brand tractor to do the job instead of getting my good tractors all full of dust? I happen to be very proud of my Cubs and clean and wax the one I mow the grass with which is an SLT 1554 that is ten or so years old and looks like new.
I thought this was supposed to be a friendly forum. To tell you the truth I am disappointed that one of the most informative forums on the net has given me criticism as to the use of my equipment and why I chose to do something a certain way rather than help me with my problem. I give thanks to the ones of you that did help. |
Sam Mac, I agree with you and have considered drilling out the jet. I have a set of drills to drill out torch tips which are great for that.I'll just gauge it with a drill and use the next one bigger and see what happens. Worst case scenario, a new jet is only $11.
Here's to experimentation..... and maybe some knowledge. By the way there are no fuel screws, just an idle speed screw. I hate to run it with a lean fuel condition as this makes it run hotter. |

Maybe I should tone it down... |
