Absolutely outstanding video. I have the exact prob. I even stored it with stabilizer last year and ran the gas dry prior to storage. Sure would be nice if Toro have made an easy access door for that carb. Thanks for the great and easy to follow vid.
@@PhillipNeely Thank you Phillip, I really appreciate it! I agree, it sure would be nice if Toro made it easier to get at the carb. Definitely some labour involved to get at it. As for fuel stabilizer and running your unit dry for storage, that usually works however I see the odd case where it does not. Unfortunately there will always be some gas in the system especially in the carb even if you run it dry. The best way is to run your unit completely out of fuel then add engineered fuel. Run the unit for 10 minutes then store it. This fuel will last up to two years in your unit. If you have a light winter and you don’t end up using your snowblower, it should still start the following winter. You can add fresh gas when you need to use it again then repeat. That’s the only way I can guarantee a machine will start for the customer after storage. I will be making a video on this topic because I get it all the time. Thank you for your comment !
Excellent how-to video. I'm surprised how difficult Toro made those covers to remove and the mounting of the gas tank. And once again no fuel shut-off. I have a couple of Toro 2-stroke throwers that are easier to work on.
@@James-dt7ky Thank you James! They definitely made it a time consuming process which would otherwise be a straight forward repair. Shouldn’t every small engine come with a fuel shut off valve? Nothing beats those good old 2 strokes. Hold onto it if you can!
I have two questions. I am considering putting a fuel shut off valve in line on my 621 E toro snowblower and also wonder if anyone has cut out part of the black plastic that inhibits the access to the carburetor. It doesn't seem to serve any purpose that I can tell other than to hold the choke mechanism and that part could be left intact i think.. BTW very nice tutorial!! Best I have seen
@@terry2346 Thank you Terry, I appreciate it! All small engines should come with built in fuel shut offs from the factory but unfortunately very few do these days. I would definitely recommend installing one to make your life easier going forward. As for the plastic cutting to gain easier access, I don’t think it would be an issue as long as you keep the choke area strong and avoid compromising the integrity of it. Hope you can find a way to make it easier to maintain and service your 621E
Great video - thank you! However, I did everything to a T and it's still surging. My carb didn't seem dirty at all to begin with. Any further advice? Clean gas. Maybe the fuel filter?
@@michaelgray48 Sorry to hear you’re having issues Michael. It sounds to me like you have a fuelling issue. I would quickly check to make sure your fuel flow from the tank to the carb is good and steady. If you have low flow then remove the fuel filter and check again. Be sure you have fresh fuel. If you removed the carb to cleaned it out but the fuel was contaminated then that could be the issue too. Drain a little fuel out of the carb bowl drain and check it for dirt/moisture.If that checks out I would go after the main jet again. I know you mentioned you followed everything to a T however you mentioned your unit only runs well on 1/2 choke. This tells me your simply not getting enough fuel. I would remove the carb and pull that main jet to check it again. You could run a micro drill bit through it to open it ever so slightly. Hope this helps!
I put a amazon carburetor on one of the toros with Rtec engine surges. Runs fine on 1/2 choke. Think i need to drill jet or check that gasket not out of place
@@mikehrdlicka8635 I think you’re on the right track. I would start with making sure everything is tight and your gaskets are in good shape. If all is good there then you could try oversizing your jet using a micro drill bit set. It’s likely not getting enough fuel. Worst case pick up an oem carb and call it a day. Good luck!
@@Ryan-hw3xp Hi Ryan, two things come to mind for a high rev/over revving assuming it is revving much higher than it normally would under normal operating. It sounds like your throttle is stuck wide open in the full throttle position. Check your throttle linkage is moving. Check the top of the carb and be sure the actual throttle mechanism is moving under spring tension. If the whole mechanism isn’t moving then you have a seized throttle likely in the carb. I do see this from time to time. Spray penetrating fluid on the top of the carb where the throttle arm is. (Between the black plastic top and the carb housing). Give it some time to creep in then use pliers to move the throttle very gently back and forth. Keep spraying penetrating fluid while doing this. Be very careful when rocking it back and forth and be very gentle as the top of this is plastic and could easily break. If you free it up then be sure it moves freely and does not get stuck one way. If your throttle is very loose and doesn’t have any tension on it then check your return spring. If that checks out then you likely have a broken governor gear inside then engine. Hope this helps!
@@notsurluap I couldn’t agree more. If they made an access door for the carburetor then we’d be all set! Do you have access to ethanol free fuel? If not have you considered putting engineered fuel in your Toro for storage? This would help avoid having to clean your carburetor
One of the best ACTUAL step by step videos I have ever watched!
@@bbrownm1 I really appreciate your comment. Thank you! Hope this helped you repair yours 🔧
Fantastic video took me about 45 minutes to an hour runs like a top wife is Happy thanks
@@Wjk1457 Thank you for your comment! Wow I think you repaired yours in record time haha. Happy wife, happy life 👍
@OttosSmallEngine I'm also a welder heavy duty mechanic
@@Wjk1457 Great to hear! I’m sure you have no shortage of work
Thanks, very good tutorial now I will go and see if I can fix my s blower.
@@AshrafMohammed-h6f Thank you, hope it helps 👍 Good luck with your repair!

Great video - thank you! However, I did everything to a T and it's still surging. My carb didn't seem dirty at all to begin with. Any further advice? Clean gas. Maybe the fuel filter?
Also, it runs almost perfectly on half choke with only a little hiccup every 20-30 seconds.

My 621E , when I start it with the choke on then the rpms are fine but as soon as I unchoke the 621 the engine revs up very high

@@itrrfan2itrrfan281 No problem, thanks for tuning in!
Using a battery powered tool to remove the carb drain bolts is very dangerous. A spark could ignite that fuel.
Just makes it a bit more exciting 😂
I am cleaning out my carburetor once a year. Toro please redesign your covers for easier carburetor access.

You don’t have to clean the carburetor out once a year if you run it dry
