OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines fuel running out of the rubber primer need help.

i have a victa v160 (tornado classic) 2stroke mower which has not missed a beat since i tried to give it a cleanup. it has a round cover to access the carby, a srew in the middle, one direct line from tank to feul tap then from fuel tap to left on round cover to carby, and on the right hand side a rubber fuel primer, and on the inside of round cover a semi circle float that just sits over a little plastic rod which sits just below the fuel intake. the float and everything seems fine, but when i put it back together it started fine then when i stoped it i noticed fuel pouring out of the rubber primer. ive taken it back of and put it all back together with no fuel comming out then when i push the throttle up to high then back to the start position it pourrs out fuel again. it would be greatly apprieciated if anyone cold help me because the amount of fuel ive wasted trying to fix it would of mowed my lawn for a year.

I would suggest the needle that the float pushes up is either the wrong way around or missing. Cheers Joe.

Thanx mate, where the fuel comes in and comes down through a hole above the float Ive obviously lost the needle out of it then. Would u have any ideas how I could fix it myself or can u still get parts for these old mowers. Cheers mate

The needle is easily still bought (that carby is still in use today) should be no more than a few bucks, it goes pointy end up into the hole where the fuel goes into the float chamber

I am having the same problem .

with both lawnmowers ive acquired.
I thought i could get 1 out of the 2 running . but nope
are these needles sold seperately?

also there was a link Bruce had on carby information?
the link is outdated?
help would be appreciated

Your local mower shop will have the needles for under $2 each.

I too have this problem.
I have pulled all of carby apart to clean (as was not starting), put all back together (have checked and all seems to be back together correctly). In the process i have replaced with new, the float, o ring & needle, and now have fuel pouring out of primer. Have read most of comments on this topic, attended to them, but still having problem, all suggestions welcome urgently.

It appears that your carburetor is flooding, due to the needle not being properly pushed into its seat in the carburetor housing, when the float rises due to high fuel level. Most likely your needle is not correctly installed. The tapered end has to be put in toward the seat.

thanks Grumpy,
I have checked this a couple of times, all appears to be ok...
are there different lengths of needles, and perhaps I have a shorter one, thus not being pushed up high enough into the seat by the float?
there is movement by both the float and needles, so neither are sticking. I cant seem to work this one out? The needle I have is black, and my model a Commando 2002. (plastic carby), would greatly appreciate any further advice.
regards
steve

I'm not a plastic carburetor guy Steve, so we need one to help us out here. However you may be able to sort it out experimentally if necessary. Can you remove the front cover of the float chamber compartment to reveal the float, with the carburetor still on the mower? Just lift up the float gently with your finger, and turn on the fuel. Remember it's a tiny float, so only apply a tiny amount of force to the float, just enough to overcome its weight. If fuel flows through the needle and seat, you'll have proved that it isn't working. Then experiment to find out why.

Thanks Grumpy,
Yes i can do this, a great idea, and will give it a go. many thanks

Does it leak with the old needle instered? I have had trouble with new needles before. Otherwise I would hazard a guess in saying the primer cap could be due for replacement as they can get somewhat bowed slightly over the years and can cause havoc.

Smack the carb with the handle of a screwdriver.


The only trick is doing it hard enough but not too hard, dont want to break anything.




If you are worried about the needle length you could undo the pilot screw and turn the primer face anti clockwise. So the arrow on the bottom is more at 1130 or 11 o'clock. Test it like that and see if it leaks.
