MTD rider Tecumseh OHV125-206604B. How to increase rpm at full throttle?

MTD rider mower

Eng and carb Tecumseh OHV125-206604B
Id like to get it running faster(eng speed) at full throttle.

I just repaired the carb by replacing the bottom bowl., shes running again...actually better.

There is only one adjustment screw on the carb (Box A), its the idle set screw. Turn it counter and I can set the idle lower. Turn it clockwise and the idle/throttle increases, but then won't return to lower idle if I increase it to where I want it.

There another screw, to the right of the carb(Box B), where the choke and throttle cables connect too. Where they connect has a spring loading 'arm" thing.
The screw is on top of this connection plate(Box B), kind of at a wired angle. When I turn this screw, not much happens.
These are the only screws it has.

Ive loosened the cable itself where it tightens at the carb(Box C) and the cable at Box D, and have adjusted where I get full open and full closed positions usuing the manuel levers.

I lke the current idle speed, but just want a little more power at full throttle.
What am I doing wrong?

No replies.....

anyway...i solved it...thanks anyway.


I disconnected the throttle cable, loosened BOTH screws OUT(box A and B), The second screw (box b) I turned to 'set' the idle while throttle was disconnected, reconnected the cable and made the cable taught, restarted, adjusted idle screw(box A)

Then, just to the left of Box D you'll see the 'tab' that stops the mechanism from going to far right...I bent that just a little bit further rigt to allow it to go further.

Now I have a low nice idle and the rpms that sound right.

This "group" or forum is 100% worthless.

Twice Ive posted asking for help and not ONCE have I recieved an intelligent reply.

Delete my account...a homeless person can better answer my questions.

Wow, in 4 hours you decide you should have a reply? Look at all the other posts here and see all the replies. Maybe no-one knows how many settings you've screwed up with your random indiscriminate screw turning. Most of the experts check in when they have a chance... might not work with your demanding schedule I guess.
