OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Victa with Briggs engine and plastic carb-governor problem

Hello guys, I bought this, fairly new looking Victa mower from the recycle centre. It has a plastic carby of a type I have not seen before. The carby mounts on the engine by friction on the intake manifold. There aren't any bolts holding the carby on. Anyway that's not the problem. It will start and run at stall speed but If I move the governor arm, it will run normally, as long as I hold it. It looks like a very simple set up but I think there is something missing as nothing moves the governor arm and it is very loose and free to move. When it is running, I can feel resistance on the governor arm when I move it, which tells me the governor is working. There must therefore be something missing or wrong in the linkages. In one of the photographs there is a hole in the governor arm where I think a spring might go. If someone is familiar with this set up can they have a look and tell me what is wrong. Thanks. Serial is 13 1217 51 99965

I can't help Sparker I have only come across one of those and it was a while back, I couldn't even find the main jet to clean it. I just dummied it up to get it running for them and I have not seen it again, not sure what that tells me. AVB once again is the go to man for this.

Yes, I was dumbfounded by the inside of the carby too. I did the same as you. Everything just says,"cheap and nasty" but only time will tell. I am sure what I am missing is just a spring so I hope AVB has a look.

I would need the info off the engine (model and type numbers) as the serial number posted just comes with the SVCS466 Victa mower and Briggs Power Portal here only lists the operator manual for that consumer walk behind.

I do know on that plastic the bowl screws are not to be over-tighten or they will strip out. I done had to replace one because owner strip them out, Other they are simple to maintain even though do clog easily from bad fuel.

It does appear it is a 09P6 series and that you are missing the governor spring.

Hey, thanks AVB. I will see if I can find a diagram for that series and see if I can get a governor spring for it and where if attaches. I can see another serial number stamped onto the engine but it is very hard to read.

The best I can make out for the serial number is 9P602-0058-H1

The serial number for the engine is 9P602-0058-H1. Looks like I need part 590541 - as AVB said - "Governor spring".

Hi All,

Attached is the parts list for your model 9P602-0058-H10

Thanks Bruce.

Is the year of manufacture for this mower 2000? The mower looks newer.

Provided the serial given is the Briggs date code then it is a 2013 Oct 03 for the engine but that serial on Briggs Power Portal actually pull up the mower which has an operator manual with a copyright date of 2012.

Plastic carburettor did I read? Did B&S gain some inspiration from Victa's LM two stroke carburettor?
If it's from 2013, you always have the option to wack in a PowerTorque, should the B&S put a leg out of bed. That is a very late model chassis, but not too late for 2 stroking. Good luck getting the Briggs successfully operating though.

MF, Briggs have been using plastic carbs probably as long as Victa has on their carby mounted on the petrol tank, this carby we are talking about is a carby with a float and the fuel tank mounted above it. And no, no chance of fitting a PT to it, it would require a long shaft PT and the height adjuster bar would hit the head.

G'day folks,
Sparker, 9P602-0058-H1 is actually the Model and Type codes for this engine - Briggs dropped actual serial numbers back in the early 1960s.

The manufacture date code is the 8-digit number stamped just after this one; format is YYMMDDxx where 'xx' is the Briggs plant location code.
E.g. if the code is '13121751', it was made on 17 Dec 2013 at plant 51.

BTW, another good download site for Briggs IPL's is http://bsintek.basco.com/MDEXResultsPages/default.aspx

As NormK says, Briggs' first plastic bodied carby was the Vacu-Jet tank mounted 'Minlon' body type. Dunno offhand exactly when they were introduced, but these are described in my 1981 vintage Briggs repair manual.

Their plastic bodied float type carbies came along relatively recently, and are a conventional design, with butterfly throttle valve. Unlike the G4/LM!

PS: The Repair Manual for this engine is HERE - 15MB PDF download. That should help with working out exactly where the spring goes.

Thanks everybody. Got a new spring for a princely sum of $3.50 which I thought was pretty good. Found where it goes from the parts diagram and now it purrs like a kitten. Plastic carbs are OK in my opinion after seeing so many chondas' with rusted out bowls. Thanks for the year built information. The mower doesn't look like it has done much work. Mackay is very patchy with its showers so if you're not lucky enough to be under the cloud dishing it out then you don't get any rain. I have seen it rain at my place but miss the street a 100 metres away! Cyclones are another matter. This mower may have been lucky in that regard. Most of the mowers I get from the recycle centre I sell for $85-$95 after the necessary repairs but this one is a little better.

Maybe I can screw a little more out of it....
Thanks all.

Actually that OHV single manual doesn't cover the 09P but is a good starting point. Briggs hasn't released a service manual for that is specific for it. We have to use our training and experience to figure things on our own.

The following APSIs and DSB covers this engine.

G'day AVB,

Many thanks for that additional info.

It doesn't really surprise me that that Repair Manual doesn't specifically cover the 09P model, as it was published in 2009.

However, if you ask which Repair Manual to get for that model, in the B&S User Community section of their website [ HERE], that's the one they'll point you to! As the 'basic repair manual' only; and they don't mention any additional model-specific docos, let alone provide weblinks...

I guess this is one of the new Victas a bloke was telling me about, one his neighbor bought about a year ago. Wouldn't start when he went to use it a few weeks ago, took it back to the shop and it cost him $200 to get it fixed.The bloke telling me the story was very happy with the $80 2 stroke he bought from me, he knew he was miles in front

I think people are put off by the noise and smelly exhaust. I have a friend who used to tinker with Victa 2 strokes and even powered a go kart and push bike with a 160, but insists on mowing with four strokes as he says they are more "civilised". He was using one of those V40 Chondah Victas in unusually tall grass and it kept stalling. He admitted a Victa 2 stroke would have been a lot better for that. I said you should keep one handy and he agreed. It has been over a year and no 2 strokev and I doubt he'll get one.

Thanks for the information AVB.

I think that's my problem with the spring.......
