Is this a sanli engine? Cause its got lawn beetle sticker but then victa on pull start lol. It has great spark but wont fire up at all lol

It seems to be one of the multitude of Chondas on the market. You might take a look at this thread:

You will notice that it is much the same as one of the versions Joe Carroll posted a picture of. The dress parts such as cowl and fuel tank tend to vary a lot between versions, and several of them have unique air filters. The one in your picture may have been retrofitted with a Victa V40 starter (the V40 having a basicly similar Chonda engine, that uses the same starter anyway).

The engine may not be difficult to get running properly. Some of them have endemic problems with heavy-handed tenants who mess up the speed control so they won't start, then trash the starter by trying anyway, after which they scrap the mower and put on a huge turn about alleged poor quality. I do not think serious problems are usual with newish Chondas, but they may have relatively short lives because of inferior materials.

That problem your talking about with the starting problem? Is it a easy fix?

Indeed it is a sanli lawnbeetle engine, victa used the same engine on part of their budget range. I sold the sanli in my thread for $30 just to get it out of my sight and quench a thirst on a hot afternoon.

Nathan, people seem to be able to operate the speed control on the handlebars in a manner that kinks the inner cable, and/or breaks the plastic handlebar control. After that it is all downhill, ending with them scrapping the mower.

Because it is an accurate copy of a Honda engine, it will normally start with one or two pulls from cold unless something is wrong with it. Something wrong usually means nobody turned on the ignition, or the speed control cable was wrecked and therefore the kill switch was still operating even though the speed control had been moved away from the stop position. We've also had a case or two where somebody made a habit of leaving the speed control in the choke position after the engine started, causing the engine to rich-load and stall. After this had been repeated a few times the spark plug was fouled and the combustion chamber crudded up in a big way, and it was never going to start again until the plug was cleaned and the tenant changed his or her behaviour.

I'm not saying that Chondas are good, durable engines - there are serious questions about how long some of their parts last, due to use of cheap materials in place of the materials genuine Hondas use. It could also be said that their speed control mechanisms and cables may be tinpot and fragile.

I tend to dissagree with Grumpy a bit.

They are rubbish. They are a copy of a good thing, but copied in such a way as to downgrade the the original design by cutting corners on the original design, the quality of the materials and design execution in general.


Non working correctly throttle cable or control is one thing. (very common issue on the Talon mowers too, business end is under the cover and you can not see that it is not working) Then the linkages, check to see that they are functioning correctly.


You didnt give much to go on. If all you have checked is spark, you could probably do more before asking in here.
Have you had the carb off and had a look inside it???


First. Flywheel key. Not sure what they have but check it. Most likely you wont even have to remove the flywheel.

Start with a new plug. Or at minimum a known plug. sparking outside a motor is a different thing to in a smelly wet hole in 8x atmosphere.

A common issue with these is bad jetting. Perhaps that should be rephrased as unforgiving jetting. They can be hard to start as they are too lean. Try starting with the air cleaner off. Well the air cleaner lid off. I had one here that I messed with, it just started when it wanted too. No rhyme not reason, just when it wanted too. I mentioned it to a mower fixing guy and he said get a drill and put a hole through the aircleaner element. Didnt pay attention to what size he said as there is no way in the world I would do that, if your gunna have a hole you might as well put on a fancy chrome trumpet and have no air cleaner at all and mow your few hours of engine life out in style
A parts list for the motor would be your best thing, one that explodes the carb entirely. If it is a copy of a honda carb it should have a removeable emulsion tube, ive seen them crudded up plenty.

Check the valve clearances, if they have closed up on any 4 stroke it will be hard to start.

Check the valve timing. Cam gears were an issue. Easiest way to check would be to just see if both valves are shut at TDC power stroke, exhaust opens on the upstroke and the overlap period at the next TDC then the inlet.




After all that bagging out I will admit that the Sanli / lawnbeetle ohv motor does sound pretty saucy. I have a few dunga chonda bits around the joint Beetle x 2, a GMC and a Ryobi. And the intention was to rig one up on some sorta Putt Tutt get around convereted ride on for my Daughter and Nephew.

Cheers.

Bob, a Ruixing carburetor is usually - maybe always - used on the Chondas, and it is a very accurate copy of the Keihin BE used on the genuine Hondas. Generally speaking, the parts are interchangeable with genuine Honda parts. You can clean the Ruixing carburetor properly by using Honda's Keihin maintenance instructions:

I've been guessing that because it is a Chonda, it has only run one or two hours before the previous tenant destroyed the speed control, wrecked the starter, and threw away the mower. Hence the other checks you mentioned might not be relevant, because the engine would not have run enough hours. However I do hold the usual original equipment spark plugs on Chondas in disrespect, they don't always work to begin with.

The most common reason for genuine Hondas not to start, aside from crudded up fuel system, is that the coupled choke linkage has been messed up and the choke is no longer closing fully, if at all. I expect this to be at least as common on Chondas, which have inferior linkages to save a couple of cents.

The jetting on my own Chonda version of the GXV160 is effectively the same as Honda uses (emulsifier drilling may be different number of holes, but same outcome). It doesn't run any leaner than a Honda. Having said that, Honda's carburetors are vulnerable to gum build-up in the main jet, and the Ruixing ones being identical, will have the same vulnerability if the engine has been used extensively or with inferior fuel.

The air cleaner should never be interfered with. If the engine runs lean, I am confident it will be because the jets/emulsion tube are dirty, the fuel filter is clogged, or the intake gasket has been split and now leaks air. These things are always easy to find and fix.

And having said all that Bob, I don't really disagree with what you have said, as usual (except when it comes to welding up sprockets, of course.)

Ok progress on this mower. Now i removed the bowl n cleaned gunk out of the bottom of bowl n i cleaned the jet that goes up the middle. An i got it to start. But the pull starter is a bit dodgy its most engagin the starter cup half way through the pull stroke. An doesnt start but if i pull it real quick it sometimes engages from the start an the mower starts lol but then once its running it will run for a minuteish an then kinda rev up an die out. N i cant get it to not die out lol. What kinda things should i be looking at to resolve that.cause ifi can now get it to keep running i will just get another starter for it

It sounds as if it is probably fuel starvation, unless you left the choke closed and strangled it to death. The symptoms are a fairly good match for a blocked fuel filter: it takes a while to empty the float bowl.

In just cleaning the main jet you have not got either the carburetor or the fuel system up to scratch. You need to clean the fuel tank, the fuel filter, and the fuel tap. Check the flow rate of fuel from the carburetor with the float bowl removed. Then remove the carburetor and clean it properly, as in the threads I pointed to in a previous post in this thread. You will probably have to replace at least one of the heat insulator gaskets. You will have to clean the idle jet, and the idle discharge port. When the fuel system is up to scratch, you will need to look at the linkage of the coupled choke, making sure the choke closes fully when you put the control in the choke position, then opens fully when you click the control back to the run position.

Because of the decompressor, you should not expect a Honda to start if you don't have the starter working properly for the full stroke of a proper, full length cord.

Part and parcel of fixing mowers is stripping down and cleaning out carbs. At least do that before asking for help.

Its clear to me from what you said that the starter is not right. Why bother doing anything if you have not sorted that out? All you are doing is risking breaking a starter for a V40, something you could use at a later date, or something you could sell or swap to someone else.
I would say that someone has fitted that but the starter cups are different between the V40 and the Sanli.

If you really must mess with it, and yes it might be a handy thing to know you have a good running sanli motor in the spares pile, Take the starter off and notch the starter cup and start it with a good old fasioned rope with a knot in the end.
