Impellar kits

I have seen vast improvements in snow removal with the addition of impellar kits on two stage blowers. I'm not sure I would install them on my machines for my concern would be overworking the design capacity of the engine , and two , would it not introduce an added imbalance on the rotating assembly . Do you think that is a valid concern?

I don't think it ads any extra load to the engine. At most maybe slightly until they break in if you install them too tight.

As for the balance you should keep all the parts the same and keep them on opposite blades to keep the balance pretty even. The truth is once you get snow and ice in there the impeller isn't really balanced very well anyway.

Please direct all snow blower questions to the forums and not to me with PMs.

Guys been running them for a few years now and nothing has come up about overworking their machines. No balance problems either. I've made my own and also used the actual clarence kit and they both work well. I think you'd know by the sound of your engine if you were overworking it. As SHRYP said though. Don't install it too tight.

I also have been running homemade impeller kits for years with no issues. You will know when you are working the engine too hard. If performance starts to drop off from overworking either select a lower gear or take a smaller bite.

When you do the install you are merely closing the gap with your impeller namely the rubber should only touch the housing.
Clarence impeller kits are in your own city, maybe pay them a visit?
Good Luck

'Closing the Gap"....Always wondered if Mfr's calibrate that gap , maybe for marketing purposes, like allowing larger frame machine using same smaller HP engine...and thus wider gap on impeller..and customer feeling they bought a bigger machine ? Gap does seem to vary among models....I have not installed on mine...Have seen a few blown connecting rods on Tecumsehs -- didn't really feel like adding a reason..

Tec blown connecting rods can be traced to poor oil changing procedures, lack of oil and tilting the blower. You can do the same with a Briggs, just more of the Tecs around and they get the bad mouth

I've seen many impeller kits.....I like the Teflon or plastic cutting boards....as for me, it's the impeller housing that is most important. however I favor the cutting boards for attaching to my impeller.....I'm still looking for a epoxy coating to both the housing and the impeller to help slick both surfaces.

Take a look at places with cooking or sewing supplies. There are things like plastic self-healing cutting boards there along with various others. Some are rigid material while others are flexible.

I've used the thicker kitchen ones to make tablesaw throat inserts for a few years. Very slick and easy to shape but these are very rigid material and about 1/2" thick.
