Rick, I have a tecumseh lv198 engine on a lawn boy lawn

Customer Question

Hi Rick,
I have a tecumseh lv198 engine on a lawn boy lawn mower. I recently cleaned the carb and replace the needle seat, bowl gasket and main jet gasket. It restarted fine, but runs at higher rpm than before. I believe it's too high for the machine. How do I lower the run speed. (this model has no throttle, its factory set to run at one speed). Thanks in advance!!

Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you.

Please take a look at the image below. That is your control bracket assembly.

Expert:  Donald replied 1 year ago.

First, check to make sure that your throttle linkage is not binding. Then check to make sure that the throttle shaft on your carburetor is moving freely. If all parts are moving freely, with no signs of binding, you can move your control bracket, in order to lower your rpms. Loosen the two screws that secures your control bracket to your carburetor, then slide the bracket forward. You will need a 5/16" wrench to loosen the two screws.

My carb does not have the 'control bracket' illustrated. The only 5/16 bolts are the ones that hold the carb to the throttle body.

Were any of those numbers helpful??
Expert:  Donald replied 1 year ago.

Thank you for the additional numbers. I used your numbers to pull up your engine. Even with your specific numbers, the image shows a control plate, although your engine does not have one.

Can you take a picture of your carburetor and linkage assembly?

Customer: replied 1 year ago.
just took a few. Where do I send them??
Expert:  Donald replied 1 year ago.

You can attach them to our discussion, using the paper symbol, after you save them.

Customer: replied 1 year ago.
OK...I'm trying to figure out how!!
Expert:  Donald replied 1 year ago.

Did you take them with your phone, or with a digital camera? If you took them with your digital camera, you will need to save them to your computer first. After you have saved them to your computer, you can attach them right from this discussion page.

Do I just drag and drop??

Donald...they are attached to the mail....
Expert:  Donald replied 1 year ago.

Thanks! I will take a look.

Expert:  Donald replied 1 year ago.

Okay I have marked your picture. Please take a look below.

Expert:  Donald replied 1 year ago.

Locate the tab that your throttle spring attaches to. You can use a pair of needle nose pliers to bend this tab forward, to slow your engine speed down. The farther forward you bend this tab, the slower your engine will run.
