Jgoodsell 19 #1 Posted January 6, 2016 I am currently working with a freshly rebuilt 10hp Kohler motor that mowed all summer. Since running it at full throttle I have noticed it is again pushing some oil out of the breather towards the top of the engine. I think that It may be adjust to too high of an RPM and that is causing the oil to be forced out since it is running too fast. I do not have a meter than can measure RPM's as I have seen some people post about though. Any suggestions on what to do about getting her to run better in the snow? The blower is a single stage 42" Wheel horse that was bought brand new by my dad back in the 70's. I have cleaned it up and redone all of the paint on it too. I have talked to lots of people here and they have had no issues with the same model throwing snow. Also put a new chain on her. Any ideas? Share this post Link to post Share on other sites
Shynon 7,435 #2 Posted January 6, 2016 Was It just rebuilt or have you been mowing all summer? If just rebuilt, check the breather and make sure it is installed with the drain hole on the bottom. I would advise you need to set the RPM at 3600 or risk motor damage. Sounds like you governor is not set correctly causing it to bog down. 1 Share this post Link to post Share on other sites
Jgoodsell 19 #3 Posted January 6, 2016 Is there a way to see what the RPM's are running at without a meter? Share this post Link to post Share on other sites

mmmmmdonuts 274 #5 Posted January 6, 2016 Thank you for that tip ekennel. I never thought to use a multimeter as a tach. That is awesome. 1 Share this post Link to post Share on other sites

Kegler 68 #8 Posted January 6, 2016 Great tip on using the meter as a tach, Have worked on motors for many years and had never heard this one. If you didn't have any problems with it while mowing I would be looking for something binding up on the blower. Might want to check your oil to be sure it wasn't over filled causing the blow back.

elcamino/wheelhorse 9,045 #9 Posted January 6, 2016 Just read the thread on using a multimeter to measure RPM. Unbelievable I printed out to but in my reference notebook. Hats off to Save Old Iron. 2 Share this post Link to post Share on other sites

PaulC 341 #11 Posted January 6, 2016 http://www.amazon.com/CyberTech-Digital-Photo-Tachometer-Contact/dp/B001N4QY66/ref=sr_1_3?ie=UTF8&qid=1452115079&sr=8-3&keywords=RPM+TESTER I purchased one of these for testing my RPM's. It will work on pretty much anything that has a spinning surface so you could test the rpms of your box fans at home if you want . It really has been a great tool though and it wont break the wallet either. I put one of the square stickers on the pto bell and its still there to this day so i can pull out that tester and check it at anytime in the total of 1 minute. and as far as bogging with the snowblower did you try adjusting your ground speed? with a single stage you need to keep the rpms of the auger up and going to fast with to much snow will bog it down for sure. My brother tried to clear my driveway once for me while i was out of town and when i came home he told me he had so much trouble with it that he ended up shoveling! Im pretty sure he was just trying to barrel right into the snow and then got frustrated when the motor bogged down. Share this post Link to post Share on other sites
Jgoodsell 19 #12 Posted January 7, 2016 Thanks for the replies and I will be testing SAVE OLD IRON's suggestion with my Multimeter. I did not have enough time tonight to test it, but I will try tomorrow. If I am unable to make that work, then I will probably take PaulC's suggestion and pick up that one off from Amazon. I need to deal with this before I ruin the engine that I just spent lots of time and money rebuilding. I did however get to enjoy plowing with it tonight as I think that it is not going to see that snow blower again. That blower was originally purchased for use on an 18hp 418-8 that my dad had stolen from him. I am not sure unless told otherwise, that a 10hp should be handling that snow blower. No lost oil this time either, but I did not use it at full throttle either. Half seemed more than enough to give my neighbors a nice snow bank to enjoy!
