277 cc is equal to between 7 and 8 horse power
357 cc is equal to about 13 horse power.
Brigs changed their rating several years ago when every thing went metric. I googled this information.

I just bought a brand new yardworks snowblower 357 cc works great but it dosent seem to throw the snow very far for such a big motor any suggestions?


it would depend on the kind of snow you are blowing
check for proper tension on the belt
you can add rubber to the blower paddles to take up space on the outside of housing check youtube

Snow blower will not throw snow far


I take it that you have a 2-stage snow blower, that is is has the auger blades and then the 2-stage impeller. The impeller blade is damaged <<OR>> the motor is to small to through the snow far. If you have a 5-horse engine and throwing heavy snow, the snow may not go as far as the light fluffy stuff.
A single stage snow thrower is not designed to throw snow far, just move it over a bit.

What is the head gasket torque spec for a 8.5 horse power horizontal shaft brigg and Stratton engine.


not nearly as critical as you think. I bet 40 ft lbs on all bolts would be fine. It's more the consistency among the Bolts than the actual torque

Dipstick mangled


Any chance you can post a picture of what is mangled ??
If it's the bottom end of the stick that goes into the engine the only way that's going to hit something is if it's the wrong dipstick and too long.

When snow is the least bit wet the blower won't pick it up and it gets cloaked in the shut. Will spraying the shut with WD40 or PAM eliminate this problem?


it sounds like you have a pretty small snow thrower, Here in northern michigan anything less than a 8 horse power will not work except on light fluffy snow. To answer your question, Yes that might help. any thing that reduces friction will make it work better. I really need a little more info before I can be of help on this. can you tell me what size (width) the blower path is, the horse power of the motor, the make of the device and also, is it one or two stage. when I hear back from you I'll try to be of more assistance.

357cc is equal to what in horsepower MTD


From my website: movingsnow.com. Five years ago the power output of every snowblower sold here in the United States was measured in hp or horsepower. It was a nice simple measurement that everyone was used to.

Three years ago they changed the rules and started selling snowthrowers with the power measured in gross torque. Of course no one understood what this meant and even though companies like Briggs & Stratton tried to explain it, it still didn't make much sense.

Well they changed the rules on us again.

So we just start to get used to measuring an engine's output in torque and now for the 2009/2010 season a lot of the snow blower manufacturers are dropping the torque measurement and only giving us engine size in cc's.

I spent a great deal of time researching this and I'm not going to spend time trying to explain why the engine manufactures have changed their terminology. Instead I'm just going to show you a formula you can use to figure it out yourself.

Here's the formula I used from the Briggs & Stratton website (rpm x torque / 5,252) The engine manufacturer's used 3600 rpm most of the time to rate the engine's horsepower so I will use that number in the formula. I also used the torque ratings from the Briggs & Stratton website for their motors to keep this chart simple. Other manufactures (like Powermore) may have different torque ratings for their motors. If you are trying to get exact hp measurements you should research the torque ratings for the specific brand.

For 2009/2010 MTD has dropped all torque ratings on snow throwers. The engines are only labeled in cc's.

Here is a simple chart of approximate cc to torque to horsepower conversions. It's not exact, but it will give you a better idea of how big the new engines are. I used 3600 rpm in the formula for this comparison. Assume that your new snowblower motoe runs at less rpm.

123 cc = 4 hp

179 cc = 5 hp

208 cc = 8 to 9 Gross Torque = 5.5 to 6 hp

277 cc = 11 to 11.5 Gross Torque = 7 to 8 hp

305 cc = 13.5 to 14.5 Gross Torque = 9 to 10 hp

342 cc = 15.5 to 16.5 Gross Torque = 11 to 12 hp

357 cc = 12-14?

420 cc = 14-15?

To me cc's is not a good comparison from one motor to another. It is also not a good comparison from one manufacture to another. For example, a 190cc Briggs & Stratton side valve motor will not have the same power as a Honda 190cc overhead valve motor. cc'c doesn't give you a good measurement of what the engine is capable of. True, an overhead valve motor from a specific manufacture should have more power with more cc's but there are a lot of other factors that go into determining how much power is available for you to use. The true power of a motor is determined by engine type, (overhead valve/side valve) carburetor (naturally aspirated/fuel injected/turbo) rpm you use it at (2750/3100/3650) and many other factors. I hope this helps.
