Two-stoke mower maintenance
Hi,
I have a '83 model Victa Charger that usually takes 20 or 30 pulls of the cord to get going (that's fine - good exercise!) but has recently stopped a few times during the mowing. After an hour then dipping the spark plug in petrol, it goes again, but I noticed last time there was a lot of "soot" on the spark plug. I can't really be bothered getting ripped off for a professional service, so was hoping someone out there had some advice (or a URL with advice) on DIY 2 stroke maintenance. The last proper service was about 10 years ago! Cheers, MK in Brisbane. |

A "Good service" won't fix that and if you have neglected it for 10 years you should really consider a major repair or replacement. -- Regards ........... Rheilly Phoull |

g'day mk,
yup my sentaments exactly i also reckon it is a worn out motor the only real remedy is a complete rebuild, there could also be worn crankcase bearings involved + +. not all proffesional mower repair services are rip off's but i must agree there are a lot of sharlatons around, when i repaired mowers i had a large following of customers reckon i must have been doing something right huh? but i must admit it is probably going to pretty hard for the end user to find the good guy in the pile. there is no real servicing on a 2 stroke mower apart from keep the air filter clean and use fresh mixed 2 stroke fuel at the correct mixing rate. len snipped -- happy gardening 'it works for me it could work for you,' "in the end ya' gotta do what ya' gotta do" but consider others and the environment http://members.optusnet.com.au/~gardenlen1/ |

Varoius things can cause that problem.
sometimes cleaning of the cylinder, cleaning of the pot. fitting oversize rings if the cylinder is worn. Cleaning of the ports etc. Regards, Mitch |

The last proper service was about 10 years ago! Replace the plug and if you have the know how remove the exhaust. Mechanics at work remove the exhausts from our whippers and blowers all the time, heat them up with an oxy (taking care to not melt or warp the exhaust), then tap it with a hammer to remove all the carbon. Failing that, the motor might be stuffed, or the carby, which I have no idea, take it to a professional. Having said that I had a ryobi scorpion whipper, that ran for about 10yrs (at least once a month for about 1.5hrs), without a problem. Only last year did I pull the plug out and check exhaust. Cleaned the plug, didn't touch exhaust, still goes good. Shame about the bump feed mehcanism :-( Anyway, I know a local dealer here that suggests running a ratio of 25:1 in all 2 strokes, regardless of suggested manufacturers ratio. This gives them business of a 10min job of cleaning carbon out of exhaust, and throwing in a new plug for around $25. I do run 25:1 however I can run the stihl at 50:1 when using stihl oil. Chainsaw is a 40:1 (I think), but 25:1 is just easier with one can needed. Cheers, MK in Brisbane. |

Two-stoke mower maintenance
Hi,
Just wondering, what is the correct ratio to mix my fuel and oil? (I have an old 2-stroke Victa mower I inherited from my Grandmother - at least 10 yrs old I 'spose?!) Also, over the last 6 months or so, when I go to start the old beast, it will start first pull, but then I have to let it idle for about 5 - 10 minutes (while it smokes the whole nieghbourhood out), before it actually revs high enough to start the mowing! Once it's going it works a treat, but getting it started like this is not making me popular with the neighbours! Any ideas on how I could remedy this - cheaply?! Could it be that I am using the incorrect mix of fuel and oil? A new spark plug? I'm not much good with motors, but with a bit of guidance, I'll give it a go!

Could it be that I am using the incorrect mix of fuel and oil? A new spark plug? I'm not much good with motors, but with a bit of guidance, I'll give it a go! Since it starts first pull, then I'd say it's still in pretty good nick. Could try a new plug, it wouldn't hurt, but then if it were me, I'd leave well enough alone. I wouldn't use anything other than 25:1 mix. I assume you are using that? You could try starting it with slightly less revs, that may cut down the smoke. A cold engine will not burn all the fuel efficiently, and full revs may choke the engine a little, even though it may be suggested to start at this setting. That would explain while it takes a little to get full revs, and that's quite normal. Starting at less revs, then gradually bringing the revs up over ten seconds (by feeding more throttle) may cut the smoke, and will definitely prolong the life of the engine.

g'day mick,
25:1 mix is the correct mix for it that ='s 40mil's of oil per 1litre of petrol. make sure you are uisng only 2 stroke mower oil and not maybe outboard oil. also check the filter maybe it needs cleaning or replacing sounds like there is some restriction to air flow, could also be a clogged up muffler and or exhaust port. outside of that you may have to take it in for a mechanic to look ata new plug can do wonders at times. len On Sat, 5 Jun 2004 15:01:16 +1000, "MC" none wrote: snipped -- happy gardening 'it works for me it could work for you,' "in the end ya' gotta do what ya' gotta do" but consider others and the environment http://members.optusnet.com.au/~gardenlen1/ |

Thanks for your advice Andrew and Len! I will try your suggestions,
especially cleaning of the filter and maybe a new plug! I'm also going to mix myself up a batch of "White Oil" from the recipe on your site Len - for the citrus leaf-miner on my new Lime, Lemon and Orange trees! The little buggers are right into them and I'm wanting to stay as organic as possible!
