Honda HS928 Engine Surging Between Loads
Original Message Feb 1, 2011 7:20 pm

Given Situation: Engine has been fully warmed up and the throttle is set to fast.

Scenario: My Honda snowblower surges when it comes out of the load. If I blow the snow with the throttle at either low or medium speed then the engine does not surge when the load is light but when the throttle is set to fast, the engine will surge when the load is low or minimum. As soon as it gets a full load, no surging. I took the blower to the dealer today (since no snow for few days and the wait is not too long) as I felt this was not right. I had this problem since it was brand new in Dec 2010. I will let you know what the fix is or if this is normal. Any similar experiences from Honda snowblower owners?

A few years ago "60 Minutes", I believe, did an undercover type show on auto repair shops. If I recall they purposefully made a minor elementary mis-adjustment to the engine...and they did secretly mark parts, and had a young women take the car in. Only like one shop out of ten said that it was just a simple adjustment. The rest quickly did the adjustment but then went on to replace, or claim to replace, all kinds of things. Struts, calipers, rotors, seals, exhausts, and other gismos.

You might recall that Sears Auto paid a 20 million dollar fine to settle state filed fraud charges.

There are a lot of videos about that on youtube. I think it was Jiffy Lube and a lot of places like that. They did the same thing with computers too. Disconnected the cable between the motherboard and hard drive and took them in to places to be fixed.

OPE or Auto are not the only place people get taken. There are a lot of organized churches (any form of organized religion) which can take people for a ride. There are many churches that are there truly to serve and help. OPE and auto dealers are the same, there are honest and dishonest people just like anywhere in our society.

After the carburetor replacement, my engine runs much smoother and quieter. So it was a good fix whether the dealer used a $2 part or $50 part. Replacing a jet inside the carburetor is just as much as work (maybe more) then simply replacing the carb.

"Replacing a jet inside the carburetor is just as much as work (maybe more) then simply replacing the carb."

Not necessarily.

On most OPE engines, all you need to do is pull the float bowl, unscrew the main jet and replace with another. To remove the carb, you have to disconnect the throttle linkage, and governor linkage. Then you need to remove the bolts/nuts that attach the carb to the engine. Often that requires, cowling to be removed to get at the screws and linkages. From my experience, with the machine in it's maintenance position, a jet change is relatively easy.

My guess is the low speed jet was plugged, the only thing you have to do to change that is unscrew the Low speed throttle stop then pop out the plastic jet that sits under it .

You know which one Borat--- the plastic one that has the o-ring on it that snaps in verticaly from the top of the carb. In the shop, I saw sometimes the carb body chips off a piece of the o-ring and plugs the jet when it is installed without a fuel system type lube like petro jelly or STP (Don't laugh--- great lube for fuel components during assembly, melts off after install)...

I figured out why my 1132 was surging at the end

I was doing lots of maintenance on about 4 or 5 of my OPE engines, and I looked in the tank of the Honda and the fuel pickup at the bottom is poking out of the gas. I'll have to try it again if we get another storm in the next 4 weeks (Winter is closer to the end than the beginning here), but I'll bet that's it.
