Toro CCR 3650 GTS Snow Blower

[stephanpitts]

I am wondering if your running rpm's have fallen off. With one-stage blowers, the distance snow is thrown is directly related to engine rpm's..see if you can kick up the throttle a bit. Make sure your throttle is opening all the way and that your choke is also open. MH

Motorhead64/Starfire1,

Makes sense about the rpm's but I am not sure how to get it to achieve the 4000 rpm or open the throttle. If I have the choke fully open(after it starts), it runs too rich. Thanks.

First, you gotta fine out what RPM it is supposed to be running at.. Then, find out what RPM it is actually running at (and to do that you need a tach) and once you have those 2 things figured out, you can determine if you need an adjustment or not.

You may also want to inspect your impeller blades - as they get worn (and they do) they start to have a greater gap and do not generate the same amount of force (since snow will be slipping back and bypassing the blades) - Could be all you need is a new set of impeller paddles... or scraper bar.. But again, best bet is to find out if it is running at the RPM it should.. if it is running rich with choke "off" (Wide open, run position) then *THAT* alone will be enough to cut down your engine RPM and performance.. meaning you likely need carb work. (But also might do to check your flywheel key which can throw off timing and make engine *act* rich.. not to mention, make sure you have the *CORRECT* spark plug with proper gap installed.)

bsengine,

I hear you about the tach, but this an unlikely adventure for this user. I am going for broke and I would like to up the rpm if possible. How do I do the following and kick the throttle up?

Snowthrower (horizontal crankshaft) carbs typically have the air vane mounted remotely and engine speed is adjusted by bending a tab to which the governor spring attaches

I have the picture from the URL that was posted by jwales, but the part were I would bend the tab is not clear. I take back what I previously said, the engine is running rich with the choke on and I, of course, disengage the choke after the engine starts up.

The Toro site lists the speed setting of your engine at 4000 +/- 250 rpm.

You bend the tang circled in yellow in this picture: http://outdoorpowerinfo.com/repairs/ima ... vernor.JPG

Good luck.

Thanks, that picture does the trick. I will have to try to bend something this weekend. Here comes the rookie question, I am assuming if I bend it away from the spring, I would up the RPMS?

Yes sir !

Bent the tang and it seems a little better. I bent it in the middle and leaned it away from the spring. The spring did not seem tight to me even after I bent the tang. Thanks for the advice.
