So I found out I had starter clutch on backwards spun it around and put everything on filled with oil and water. Turned it over it spun once and stopped. Drained oil and water took everything apart. Found that the piece that caches the flywheel gear had popped out. So I managed to get it back in. Tried it again starter spins all day. But just won't catch and turn over but at least it is turning over or did once. Still need advice or anything been at this for about a month. Between work. And having an 8 month pregnant wife trying to make her happy and trying to get rhino going

Not at all sure what you mean by "the piece that caches the flywheel gear had popped out". The one-way is nowhere around the gear teeth. The gears are in continuous engagement, nothing comes out and grabs a gear to make anything spin. Can you provide a clear photo of what you are talking about? This is a Rhino, and not a 1952 Chevy, right?

Where the starter clutch slides on. Starter gear maybe. You use the flywheel pulled to get off the gear

One way clutch goes into starter idler gear. The bolt in center of crankcase tightens down I guess to get the one way clutch onto idler gear I'm guessing

Here is a snapshot of the Yamaha Parts Fiche. The Starter Clutch (8) inside bore slips over the Hub of the big idler gear (6) that spins freely on the crankshaft. The outside ring of the Starter Clutch (8) is bolted onto the back side of the flywheel (not shown) and is carried onto that gear hub as the flywheel is installed. The starter clutch locks the flywheel to the idler gear (6) when the idler gear is spun by the starter motor. The flywheel is oriented by a key that slips into that rectangular slot on the crankshaft (on the left, not numbered) and is taper fit locked onto that shaft such that it cannot spin on the crankshaft.

Are you talking about the woodruff key (half moon shaped) having fallen out when you tried to put it back together? It orients the flywheel with respect to the crankshaft. and might have come out or broken after that single initial start. If the flywheel is not properly seated with the key in its proper place, by torqueing the nut that brings it all together to the proper torque value, It can spin on the crankshaft and the engine will not turn over when the starter motor is spinning.

Also, the outer rim of the starter clutch needs to be bolted onto the back side of the flywheel for the engine to turn over with the starter motor, just in case you did not do that. The bolts (9) are drawn pointed the wrong direction in the picture below, if I am not mistaken.

Ok I downloaded service manual. fresh start on it. if I'm not mistaken. I thought I felt 2 washers behind idler gear could be something else but I know it's suppose to have one washer. Have to take it off and check. Also does the woodruff key just set in the slot or should I tap it in to set fully in the slot? The service manual doesn't really say way it sets now there's a little higher than flush on the crankshaft

It would not work as a key if it was flush with the crankshaft. It has to protrude to engage the mating slot in the flywheel. Look at the bore of the flywheel and you will see how much it should be protruding to fill the depth of that slot.

You could consider using a gob of really heavy grease in the crankshaft slot to help hold the key in place while the flywheel is sliding over it. It is really important to have the slots in flywheel lined up with the slot in the crankshaft before you push the flywheel into position. If the flywheel is out of position, the flywheel will simply push the key out of the slot in the crankshaft, like a bulldozer blade. It will also help if the crankshaft is oriented with the slot up, such that gravity will hold it in position (rotate the crankshaft with the spark plug out to make that so). It is a hopeless cause to expect the key to hang in the slot if it is facing downward.

I haven't done this but what would happen if I turned crank with plug in? Would it mess up timing? Like to line up to where key is on top

If the sparkplug is in, the piston will build pressure in certain positions as you turn the crankshaft. It would be harder to turn and it may bounce back to an unwanted position when you let go. No spark plug means no compression and it makes a much easier job of it. Do you find it hard to remove the spark plug? If so, try it with the plug in and see if you are lucky.

Got rhino running. First I filled with oil and rad fluid. Put 1 1/2 quarts of oil in. Fired it up running good checked oil. None!! I cut it off. I did put in wet clutch slugs. Also. Choke is really sticky and I give it gas and it wants to die

The locking ring for the choke knob may need adjusting. At the base of the knob, right next to the dashboard is a ring. Grab it and rotate it one way to lock the choke knob and turn it the other way to release the choke knob. If that does not do the trick, you may need to lubricate the choke cable or buy a new one.

OK, so you got enough oil into it to show on the dipstick now? Do not try to run it if no oil shows on the dipstick.

Are you letting it warm up long enough for it to idle well with the choke pushed all the way in?

Have you touched the carb or the various hoses associated with it and the air-box since it last ran properly? How long has it been since the engine last ran properly?

Oil is full I keep checking it. Last time I ran it was about a month I took to of carb off and needle out sprayed carb cleaner Inside let it set drained it out and fired it up. Idles good wth choke. Push choke in still runs good put it in gear forward or reverse tap he gas it dies I did notice one I puta new starter solenoid on the fuse beside the solenoid constantly ticks until I turn key off

You have to work on your grammar and punctuation. This is unintelligible to me:
"I puta new starter solenoid on the fuse" Hmm, How did you manage to put a relay onto a fuse?
Or is it: "the fuse beside the solenoid constantly ticks". Hmmm, I've never heard a fuse tick before.

You included a picture. The relay that you have your finger on is ticking? Refer to page 9-2 in your 450 service manual. As near as I can tell, that relay is item (14), headlight relay. I have no idea why it would be cycling with the ignition switch on. Try fiddling with the headlight switch on your dashboard? At any rate, I doubt that it has anything to do with your gas pedal problem.

Regarding the no go when you press on the throttle pedal: I suspect that you might have a blockage in the main jet. Or, there is an air passage from the intake bell to the atomizer (perforated tube) that resides above your main jet. That air passageway may be clogged. Carb cleaner into the holes in the intake bell and follow with compressed air to clear it out.

Did you have any extra parts when you put the carb back onto the machine?

Yeah, real keyboards are a whole lot better. It pays to read your post before hitting the send button though.

It would seem that your carb needs another cleaning. This time do a thorough job, including the internal passageways.

While you are at it, check the rubber diaphragm at the top for any small perforations or tears. Make sure that the perimeter of the diaphragm is properly seated into the groove as you put it back together.
