OutdoorKing Repair Forum Forums Finding and Swapping Rare Finds & Donations VICTA 500 TWIN CYLINDER

Thanks emmo1980 hopefully you do have one.I'll keep my fingers grossed.Yes the fuel gauge cap is still in one piece however it looks like it's been sitting in a jug of beer,cause it has turned the same colour.

Yeah, they do tend to do that, or go white, or melt...

I cant say specifically what that cap is off, but it is quite a range, keep an eye at Mugga, I'm sure you can by a scrapper down there one day that will have it.

HELP!!!!! Ok starting to get sad.Old Goliath,that's what I've called it.Won't go,now although carby isn't happy (and will have to get another one,a bit leaky) it is getting fuel.However in the firing sequent's suck,squeeze,bang,blow.The bang is not happening.Checked spark on plugs front spark plug was very very weak (any weaker and I would have not seen it) back plug weak but not as weak as front.So now I'm at a lose.Does that mean I'm now on the look out for another ignition? Or is there something else I can do.I fairly sure that's why Goliath won't start.HELP anybody please? I really wanted to see and hear it go.

Have you done anything to the ignition, and was it working when you got it>?

No and no

OK, i would suggest fully servicing the current carby, as long as its not cracked or broken, there's no need to replace a good carburetor, especially as it may be you original. (while they are all the same, i like keeping things together if they were made together)

Then get in there and give Goliath a good ignition service, making sure to get the timing right, and when you can, re-check the spark.

The full instructions and specs for servicing your carburettor are in the manuals section. as well as the parts guides to the Victa Twin.

I will get the ignition guide, and 170cc Twin overhaul guide to Bruce, ASAP, and i will get you the copies of my book on the twin when i next come by.

Yeah I'm not to sure about the carby as I can see where somebody has used a massive amount of glue to try and repair it.So as far as saying a good carby I don't think I would consider it as good one.Also I'm not sure how the kill switch on the twin works or seen one up close,but to me it looks like a regular G4 to me.What are the noticeable differences? Ok as far as timing is concerned I would have no idea on how to do that.I do have a parts guide on the twin,but that's all I have.So I guess any manuals would certainly be a help.If the condenser has fouled up,could it cause this lack of spark?I know I wanted to know more about the twin,but I really didn't want to do it first up.I must get Goliath working.I was really looking forward to hearing and seeing it going.[Censored] Goliath you will LIVE!!

OK, if thats the case, service the other carby, and pop it on, the cut out is the same as any G4.

The old carby should provide enough parts to service the new one, however make sure it is a G4, and not an LM, while an LM would work, it would not be original to this mower.

The easy way to tell is the main jet/face screw, if this has a thin tip after the thread, its an LM, if it has a wider opening, with a long plastic tube comming out, its a G4.

Let me know when the carby service is done, and we can move onto the ignition service from there.

I'm sorry Ty you lost me then with LM.What I think has happened (now this is going to sound like I'm a dumb arse,but I haven't had much to do with these.Correct me if I'm wrong.Please?).It looks like somebody has got a G4 carby and the original twin and busted the front of the twin carby and glued it onto the G4.As it has some sort of idle speed control at the front.I have only ever pulled one G4 apart before so I'm not sure what things your talking about.If you have any pictures to illustrate them please do.

Ok, sorry for the crappy pics, my camera is dead, so i had to scan the parts.

This is the main jet/face screw of a G4 carburettor, the plastic tube can be removed.



And this is the main jet/face screw of an LM, the plastic tube is manufactured into the post where this screw threads into, if you look down the hole, you can see it on an LM carby.



You need to have the carby that has the first one, if you get the fist one, and it wont fit into the carby, then the carby body is an LM, and not a G4.

So when the main jet comes out.With the G4 the tube comes out with it? Is that right?Where as the LM won't? Am I getting the right idea? I hope I am.Cause if I am I will bring it in from the shed in a minute and have a look.

That's right

For the G4, the tube fits firmly in the end of the jet screw, and should come out with the screw.

For the LM, the tube fits over the tip of the jet screw, but is fixed inside the carburetor, and will not come out with the screw (it cannot be removed from inside the carburetor, it is still white however, and you can see it in there.

If you are unsure whats going on once you get it apart, photograph what you see (plus this glue business) and i can tell you more.

Cool I think I'm finally getting it

Ok have done that it is a G4 carby.Has the tube on the back that comes out.




The first picture of the carby is a bit fuzzy,but the bit that looks like oil is the glue.You can see it better in other pictures.I just added the last 2 to show the screw.

OK, looks like the cap has cracked and been glued up.

Can the cap still be levered off with a flat head screw driver (watch out, there's a spring under the cap that may try to run away!)

[Censored] not good.Yes it did come off.After it came off I could see that there is a hole in the cap as well as a crack from the centre going to the outside.


You can see the crack in the last photo.

Yep, that ones stuffed, however, chances are, if you clean out any dust and dirt from inside the carby, and pop another can in place, it will be good to go. (Keep the big white plastic screw)

I don't think the diaphragm is any good on it either.It's sitting with one part flopping down.I bet it has a hole in it to.It looks bad.

might just be out of place, as you clean it out you should be able to work it out, its not common for them to get holes. the caps however are often cracked

So am I able to put the speed adjuster onto another cap?
