Mechanic's Assistant: I'll do all I can to help. How long have you been dealing with this?

I have a Kohler cv16 engine that has low top end rpms. I have installed a new carb, replaced fuel lines, adusted governor and tuned up. No change alsobh

Mechanic's Assistant: Can you guesstimate how old the engine is? And has it done anything like this in the past?

Don't know how old engine is. The engine is on a John Deere lawn tractor

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes

Mechanic's Assistant: Anything else we should know to help you best?

Technician: Curtis B., Technician replied 9 months ago

Do you have good rpm before engaging blades? Are the deck pulley and blades moving freely, if you check them with engine OFF and not engaged? Is the throttle cable opening the flap in the carburetor fully?

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
Not good eough rpms. Also drops when transmission is engage
Technician: Curtis B., Technician replied 9 months ago

Can you get rpm up if you manually move throttle at the carburetor?

Ask Your Own Small Engine Question
Technician: Curtis B., Technician replied 9 months ago

CV16, do you have pulse fuel pump or the can driven fuel pump mounted to block? Maybe fuel pump is weak, and not delivering enough fuel?

Has a new fuel pump. Ran a fuel line from a gas can to the carb. No diffrence. I thought a new pump and new hose, and gravity fed fuel source from a fuel can would make a difference, but it did not
Technician: Curtis B., Technician replied 9 months ago

Is the throttle flap in carburetor opening fully with throttle cable? Can you get rpm up by moving throttle lever at carburetor?

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
The flap is open. If I move it any further it goes to choke
Technician: Curtis B., Technician replied 9 months ago

Are you looking at the throttle flap or the choke flap?

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
On this model tractor if you go past the high throttle it closes the flap and creates a choke.
Technician: Curtis B., Technician replied 9 months ago

Gotcha, same as Briggs. So is governor link capable of opening the throttle flap ? Have you check compression on engine, maybe just too weak to run mower!

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
I would agree with what you said. However, the engine seems to have low rpms. If the Rpms were raised some how it would be fine. My experience of owning other lawn tractors tells me the rpms are low. I don't here the governor trying to compensate for the load
Customer reply replied 9 months ago
Engine sounds like its at half speed
Technician: Curtis B., Technician replied 9 months ago

I you manually move the governor link, will engine rev up? Usually if governor fails, it lets engine run at too high an rpm, not low rpm.

You have service manual? Link here.

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
sir
I adjusted the governor according to the manual. Moved the position of the spring to different holes on the linkage no difference
Customer reply replied 9 months ago
Adjusted high speed figure 5-22 according to manual
Technician: Curtis B., Technician replied 9 months ago

You keep avoiding the question as to whether you can rev engine higher manually.??

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
Sorry
No engine will not rev higher manually
Same rpms manually or with throttle control
Customer reply replied 9 months ago
I thought I had answered the question
"I can move the governer manualy it does the same"
Technician: Curtis B., Technician replied 9 months ago

Have you checked the timing key between flywheel and crankshaft? Engine may be out of time.

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
I have not checked timing.
I will check timing after I get off work.
Technician: Curtis B., Technician replied 9 months ago

Has to be sometime other than the carburetor and governor causing power loss and not reving up! Thanks.
