OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines High revving Victa..again

Hi Danny and Norm,

If you haven't tried to start the mower it could be a few things ,if it's the needle sticking ,when it stopped you could have put
some fuel in the spark plug hole and if it started then it's a fuel problem , fuel flow can be restricted from a bad fuel filter or
a restricted breather on the fuel cap.

Spark plugs can fail when they get hot and even new plugs fail occasionally.


Cheers
Max.

And this is the problem with the design of these things, you can pump on the primer and you have no way of knowing if fuel is flowing through the float switch, that is of course unless it is pouring out the primer and by that stage you now have a flooded motor and that needs to be delt with before you can get it started. One way to check fuel flow is with the tap on pull the hose off the carby. If fuel runs out the hose it is usually the float needle. Then as you say could be the breather in the cap, but in all my years I think I have only had that happen twice on a Victa. And if that happens the revs usually rise as the fuel flow leans out. With the float needle sticking it stops the fuel quickly so the revs don't rise because it doesn't get time to lean out
Dan, if you get stuck with the main jet screw (pretty awful design) I can send you a few bodies reluctantly through Aus Post, but I hate being ripped by them

My 3 cents (because of inflation) is that it's a dead plug.

Good call there BT, I have had 3 of them in a row recently

I will check the plug although it is the one that started this thread a few months ago when I left out the diaphragm metal plate and this new plug nearly caused the motor to self destruct.

I was in no position to check anything at the time due to being black-laquered from my first hour and a half of mowing and whipper snippering for about 3 months!

Danny

Bingo bigted! This plug that was new at the beginning of the year was completely deado. I did get a run out of it since the time of my previous posts. I've got about 4 of these Champion BJ8s all useless.

I robbed an RJ19LM from a 4 stroke and apart from verging on being too long to get the plug lead on works a treat. I even managed to get it to run a bit slower...or did I imagine that?

Danny

Yep, you imagined it running a bit slower.

I did a couple of PT's recently and they are perfect. Start first pull and idle as they should. They are so good if the float needle and primer cap work, but it is such a crap shoot, for everyone I get to work I can usually spend hours fighting and swapping primer caps 15 times before I get a pair that will work consistently.

What I've only just worked out with the 2 running Victas I have is that some of the high running speed problem seems to be caused by the cable control having a mind of it's own and just moving independently of any human input.

One of them, a Tornado I think, (Blue 2 stroke) is particularly good at this...and I haven't even messed with it!

Danny

Hi Danny,
if you tighten up the screw through the filter housing you should be able to stop the lever moving too much

will do Norm, thanks.

Was enjoying the continued use of this machine when, a couple of months ago, the catcher started falling off! Like lightening I deduced that the rivets holding one side of the flap had broken loose.
After using it a couple of times with no catcher I got round to replacing the rivets with some lovely little stainless nuts and bolts.Started using it again and catcher still dropping off.

After another couple of uses without the catcher my meagre brain worked out that I hadn't retensioned the coil spring on the flap that apparently assists in keeping the catcher in place. Thing is it was good using it without the catcher sometimes with no spring tension as with no tension on it the flap would just open a bit to let some cuttings through and keep things clear.What's a good way to keep that flap open a bit if you want to use without the catcher?

Danny

Hi Danny,
most people just tie the flap up a bit with a piece of cord or anything they can find. I assume you have got the spring working now.

I know it's working now Norm 'cause it bit me while I was doing the new nuts and bolts up.

Danny

That is a good indication
