The Ariens Pro model 926065 with the 420 cc B&S is spec'd by Ariens for 3,600 rpm +/- 100 rpm. Has anyone increased the engine rpm to 3,700 rpm using the governor control? Is it an easy change, and how did you do it?

Thanks for any input.

WHY?????????????? Would you want to do that????

Yeh. Why?

That was the first thing that popped in to my head. Why?

Many engines from the factory run slower than their spec'd engine speed. In my experience setting the engine to the top of the spec'd rpm range gives better engine performance and therefore more throughput of snow.

The LCT 414 cc engine in AX form is spec'd for 3,700 rpm but mine was running 3,450 and did not perform as well as I expected/wanted. By changing the governor setting the engine ran at 3,700 rpm and performed very much better. I kept that setting for almost 5 seasons. The LCT/AX engine manufacturer spec'd the 414 cc engine with rpm at 3,900. Near the end of season 5 I upped the governor to 3,925 rpm and it ran better, sounded even better and performed better with snow throughput.

A friend has the B&S 420 cc in an Ariens Pro and has not used it in the winter yet, but has some demanding conditions. The thought is that the engine may be short on rpm and so perform below par. I cannot get access to his engine's governor system since he lives far away. The internet has nothing that I can find so far on the B&S 420 governor system. Now in the fall is a better time to check on stuff, rather than wait until winter snow and cold.

My thought is that some of the experienced people on this forum would know the system and be prepared to share their knowledge.

Until someone posts and exact answer about the 420cc, Taryl covers it generally in a video only he can do:

Because.... "There's your dinner"

Thanks Zavie I usually don't watch those redneck videos after the first few scenes. But that is the best video I have ever seen on how the governor system works and why and what you have to do to correct any problems that may be there. Quite excellent. He is one smart guy, and able to get the principles across completely, not halfway as usually the case.

So the question is whether that B&S engine uses the same spring adjustment process as the Ariens B&S 420 in the Pro.

Thanks for posting.

I'd be very surprised if it didn't have the exact same system.

You made my day. It's a long time I didn't laugh like that. These guys are crazy. I suspect they smoke something before doing this video
