PLEASE HELP!

I got a 2004 Ariens Zoom34. I had the deck leveled etc. I was noticing odd level cuts, heard my engine might not be runnin fast enough. Turns out that & uneven tire pressure seems to be the blame. I have a slower time starting it btw also, but I noticed at idle & high idle it is okay (I even popped the air filter plastic off to check throttle movement from inside the carb). It works fine but only at running speed is the throttle actually wide open. When I put it in full throttle, the plate closes back up as the screw pushes & makes contact with the linkages on the carb. Here's a picture with throttle lever in the groove at running speed, again full throttle closes it back up & its bogs down or will die under blade running. Help

But I should add even when its open like this, it still doesn't seem to be running as high as it should. Carbs aren't hard to clean I know but why is it closing the flow & not running higher when I go to run full throttle

So it sounds to me like your problem is dying out/ straining under load, i would remove the carburetor and clean it. specifically the main jet.
The butterfly valve doesn't have to open very much for a engine to reach full speed (about 3600 RPM) with no load.... Under load the governor may open the throttle more to compensate for the load.
Looks like a Kohler Command engine?

Thank you will definitely clean it, but how come full throttle still closes the butterfly valve completely? That mostly is what's killing my power, otherwise at high idle/running speed engine is mostly ok when the butterfly valve is open. Just not full power it seems

Its also a briggs 14.5hp engine, I can't find much on YouTube or online besides asking a forum about these

What you looking at is the choke plate. The throttle plate is the one next the engine and not the air cleaner.

Well I popped off the carb to clean, choke plate/links seemed like they had lots of play when the throttle is lowest/mid. The screw on the choke plate coming off the throttle cable that pushes the choke links etc doesn't start pushing choke until its all the way full throttle. Then dies/bogs. Sounded good low/mid throttle but won't reach highest rpms as it closes the butterfly valve in the carb & seems to choke it out

Will need the Model type and code numbers off the engine, they will be stamped into the OHV valve cover on the front of the engine

Also not sure why but everytime I go to find a replacement. I get this one exactly with a fuel shut off solenoid & mine is a Walbro carb that I can't even look up on their site! Idk if the person before me put a different carb on & bypass the solenoid, idrk. Im not slow but im also not an expert by far ??‍♂ Im so lost!

because I can't remember the actual thread size I won't mention it but there is no difference internally between the solenoid & no solenoid carbs
So all you need is a bolt to hold the bowl on .
If no one chimes in with the thread ( think it is a fine pipe thread or conduit thread ) take the solenoid to a specialist nut & bolt shop & ask them for the shortest bolt in that size.
I got my from a gas ( LPG ) appliance shop by doing just that .

I appreciate that but its already set up like so. It just seems to be a different carb than oem but if you would please look at my follow up posts & see what it might be? Like I said its fine until full throttle then it closes choke i guess and butterfly valve. Not sure if its supposed to but I'd assume at full throttle it would be all open right is the choke links supposed to be loose also when it's not full throttle? Sorry not an expert
