Hi people,

I thought I'd reach out for a little advice about my regular mower. My Victa doesn't seem to be able to run the low revs. It's all or nothing. When I go to empty the catcher and bring the throttle back, it doesn't slow until it's ready to cut out completely. How do I recitify the issue so I have my range of revs back again? If there is a video you can link me too, I'd appreciate it or simple instructions as I'm still a novice when it comes to engines.

I'm referring to the mower pictured.

Hi Okidoke

Being a tecumseh, I would wager that the throttle shaft is sticking from years of dirt and grease. Spray it with something like wd40 to loosen it up, then a bit of silicone spray to lube it but not attract dirt.

You should just be able to flick it back and forth with your finger. It should not be at all stiff. You may have to take the air filter housing off on this model to get to it easily

This thread may also help you

I can't help but I think that engine looks really good on that base. Infinitely better than a Chonda, Honda or Briggs. Very smart get up indeed.

What a shame Tecumseh are no more. We need them now more than ever as an alternative.


Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!

Appreciate that. Will give it a try tomorrow.

G'day okidoke ,Mf ,Tyler

If everything on the motor is in good order and it still revs too fast ,I sometimes loosen the top plate on the carby
and move the plate with the elongated slots then tighten the bolts back up , this gives you a little bit of a change
in RPM.

Another quick way is marking the governor shaft and linkage with a texta line or scribe a line on both then loosen
the linkage from the shaft and move the linkage so the line doesn't line up any more by 1 mm ,if you go the wrong
way the revs will increase so if that happens loosen and turn the opposite way then tighten. You do this a few
times until you get the right maximum RPM.


Cheers
Max

NormK I find any Victa with a Tecumseh exotic to my eyes. Next we'll see a thumb latch alloy chassis with one.

I've sprayed WD40 around and I seemed to get a range of revs for a couple of minutes. For a little while it did actually go back to a nice idle, but soon it began to increase revs without me even moving the throttle lever. And then, it wouldn't idle at low revs again, just the full revs no matter where the throttle was set. Does that help with an evaluation of the issue? Do I just need to spray more WD40 into it? Should I pull the carby off and throttle cable and get right in there with WD40 maybe? I just thought it was very strange that I got it to idle nice, and without even moving the throttle lever from the slow position, the revs just increased on their own.

Sounds like there could be a fair bit of dirt around the throttle area - as it still cuts off fine, you can ignore the throttle cable.

I would highly advise pulling the carby off as you say

Did you do the silicone spray bit as well?

I took off the carby and gave it a good clean up and around the area, then finished it off with a spray of silicon. Working as it should now. Full range of revs available. Thanks all.

That's great okidoke. Glad I brought it up after Tyler's invaluable tips on what to do.

Excellent result okidoke

Quite common thing these do for some reason, beside that they are a reasonably solid motor (especially with pressure lubrication), although its another engine where coils are a bit thin on the ground

Tyler,
do you have any idea what could be causing a Teccy I got to be stalling after warming up as the seller said when I bought it?

MF, I am going to be trying your invaluable tip on split Briggs quantum tanks

I was in chemist the other day to get a bottle of black enamel nail polish (MF's solution if anyone is wondering) and was asked if the nail polish is for my partner/girlfriend.

I said, no, its for my Victa haha

Make sure it dries hard before putting any fuel in. I say give it a day.
Yeah, that will shut down many people lolol!! Especially at the cosmetics counter!
