Victa Engine, Ignition Troubles

[Shane284]

Hey guys,

I recently got myself a Victa Tornado Power Torque lawn mower, or so I think. I had a bit of trouble starting it, after getting a new spark plug and the engine still not sparking, I decided to pull a wire that I thought was the culprit and then I got sparks from the spark plug, Only problem is, the wire i removed was the kill switch wire (I think that's what its called?) so I had no way of stopping the engine after it started. Obviously this is a problem since I need that wire connected so I can stop the engine, but with it connected the engine won't start.

Any ideas guys? I'm pretty much ready to pull the carburetor apart but before I do that maybe someone can save me some time by pointing me in the right direction of how to tackle this problem.

Pictures below, The white cable I think goes to the spark plug? The black one is the wire that stops the spark from happening when its in (atm it is connected in this picture, so no spark is happening)

Wire must lead to a switch which (apparently) is in the off position.
When wire is disconnected you are , in effect, by passing the switch allowing the coil to do it's job.
Locate the switch and be sure that it is working.

In that second picture, those to wires poking out of the carby are the kill switch, sort of, when you pull the throttle right back a little arm on the slide in the carby pushes the two wires together and kills the spark, simple hay?

A couple of things to check, is the throttle cable connected in the carby (it goes down the throat of the carby and intake pipe), it might be stuck on no throttle and thus killing the spark? Is it very dirty in carby? there could be dirt getting between the wires so it doesn't ground? The piece on the slide the pushes them together could be broken and lodged in there?

Heres a thread I typed about wiring a kill switch into a victa, don't know if its much use to you? Just thought I would post it up anyway, might have some useful info in it (sorry about the bad grammar in it!).

Hope this helps

Spot on mate! Works exactly like you said it does, throttle to off position pushes the 2 together causing no spark, just as you said, simple

The great thing is that when I put it into 'run' now, It does spark even with the kill switch wire connected so I can now turn the engine off, yay! The throttle cable seemed to be fine inside the craby but there sure as hell was a lot of dirt around the craby. I cleaned all that mess up, particularly the area where the connections of the wires were and I think that did the trick.

That link seems pretty niffty and possibly come in handy later on down the track, sure gave me a few ideas of what I could do in the future.

Thanks for the help Hayden.

Theres suppose to be a rubber cap on those killswitch wires. U need that on or it will get dirty n screw it up. Go to ur local mower shop n get one if u lost it or didnt get one. Or u can go here: http://www.outdoorking.com/index.php?main_page=product_info&cPath=193_514_225&products_id=594

Good to hear you got it going! Was the throat of the carby really dirty? Most are.

Yeah, one of the mowers I pulled apart just had a little o ring in place of the rubber boot, I just assumed it had that but yeah if it doesn't have one get your hands on one, take one from a mower at the tip if theres any.

Thanks

Yeah it was a bit dirty inside there, not as much as I was expecting tho. The little rubber thing was very dirty tho, which probly didn't help with the wires connecting but atleast I have one and it should keep the cables clean

atm I'm looking at a Rover lawn mower with a Briggs and Stratton engine on it, Sprint 40. Looks like its got the flywheel on top (I think) cylinder shape on top. I got a pic of it below, hope its a good one. Has Briggs bought out Victa engines?

Thanks Hayden,

Okay, you did clean it out didn't you? And get a new air filter, you can get them from Bunnings for a couple of dollars.

As for the Briggs engined mower, don't bother with anything 4 stroke, you will either have to modify the oiling system or get a right angle gearbox. I'm converting a vertical shaft briggs to run as a horizontal shaft engine by modifying the oiling system. Unless you don't care if you blow the engine up then don't bother trying to convert one because there a chance you will. So yeah, don't bother with that engine lol. Victa engines are 2 stroke so they don't need any modifications to run as a horizontal shaft engine, only the carb being turned 90 degrees which is super easy on a Victa. I'l say abit more when I get home (I'm saying this on the internet on my phone)

Thanks

Yer briggs owns everything now. http://www.briggsandstratton.com.au/

Look at em all.

 

[Shane284]

Yeah I cleaned it all up, everything runs good and works as it should. I'll look into that air filter, the one it has atm is rusted pretty badly.

I see, so basically a stroke engine can just be tipped on its side and will work fine with only having to change a few small things?
That's defiantly a good reason to go with 2 stroke then heh.

Btw would you have any advice of where to find victa engines. I've been using ebay, most of the ones I find though are power torques with the square tops :S

Ah thought so Yeah cause I seem em every where on the base of most lawn mowers.

Thanks for the info guys,
