Gday from hervey bay, I have a this motor which has had a good clean .


The numbers on the motor are g200f. 1005031168. e13*97/68sn3g2/88*0155*01 I had this motor running beautiful and then a small clicking noise come in to it . I then shut the engine off pulled the cowl off checked the coil. The coil was still tight ,I clanced over at the flywheel and pushed the plate where the screw is in the photo and noticed it was a bit loose so I undid the srew and the magnet underneath the plate was shattered. Please tell me I can buy this part sitting at the bottom of the motor in the last photo. Regards roebuck.

The 168F is one of the clones of the Honda GX160. Honda claims 5.5 hp (gross) for the original, and the 168F's manufacturer describes it as 5.5 hp but puts a 6.5 hp sticker on it. Remarkable marketing practice. You can get some details of it here:

You may be able to get a magnet from one of the importers of the engine. Otherwise a Honda GX160 magnet will probably fit.

Thankyou Grumpy ,I started to get a bit panicy about part as I'm just helping a friend out and I wasn't quite sure what to tell him. It only needed a valve ajustment. I wonder if this happens on the chonda regularly or it's just a freak thing. Try and get a part Monday.

I suggest you talk to the Honda dealer about installing it. It is possible there is a trick to it - for instance Honda might, say, put some epoxy on the underside of the magnet before installing it, so it has a full bearing area onto the flywheel. If the Chonda folks left out a step like that, it could work out just the way yours has.

Grumpy, I've been to honda and they do not sell these magnets and I have been looking on a forever list on the net and have had no luck so I was wondering does anyone have one of these flywheel laying around that they might like to sell me . Ithought I was in luck when I found one on the net but they refunded me my $33 to good to be true.please help.

Remember, you are looking for a flywheel for a 163 cc chonda - I don't think it matters whether it is horizontal or vertical crankshaft, the magnet at least will be the same, and probably the whole flywheel will. That means most of the chondas sold in Australia should suit. There are vast numbers of them out there. Outdoorking members seem to flick them aside with their feet when they run across them, and just keep walking, because they have a reputation for being difficult to keep running. You could just as easily use a GXV160 or GX160 Honda flywheel, but people are less prone to throwing genuine Honda engines away, even when they have problems.

Have you tried a tip shop? From what people report here, chonda-engined mowers seem to spend most of their time in tip shops.

Yes I'm going to the recycle centre on Thursday ,but I've only ever seen one 160 gcv that was at least 6 months ago and don't recall ever seeing a chonda but I have been lucky just of late I picked up another GV 150 . I'll keep trying though. Thanks and ill let you know if I ever get one.

The GCV160 is nothing like the GXV160, and nothing like a chonda. Personally I'd be disinclined to pick up a GCV160 if somebody abandoned it on my nature strip. I'd rather have a chonda.

I'll look forward to hearing from you when you get the flywheel, roebuck.

Hi Grumpy, moving a little off topic, in your opinion what is it that makes a GCV160 an inferior honda engine?

Hi bigted. The Honda engines with the C in their designation are the "residential" series, where those with the X are the "commercial" series. The Cs are overhead camshaft instead of pushrod, and are designed quite differently. The rubber cam belts wear and jump after a while, and the engines have to be split to replace them. They have an integral cylinder head, so the crankcase splits diagonally to enable the piston to be removed from the bottom, and this makes splitting the engine more difficult than usual. Of course, valve lapping is awkward from underneath, and the piston ring compressor has to be removed from inside the crankcase after installing the piston. Oil sealing is minimal - there is no oil seal on the governor shaft, which not-infrequently leaks - and the plastic camshaft and cam-sprocket is all in one piece with just one lobe: intake and exhaust rockers run on opposite sides of the same lobe, like on the old Triumph Dolomite Sprint car engine. The plastic camshaft is just a large sprocket with the single cam lobe moulded right on the back of it, so it is quite flat, but despite that has a reputation for fracturing. The camshaft rotates on a loose steel bar pushed through its center: you can just pull out the bar to lower the camshaft so you can time it on the belt. The carburetor is a slightly cheaper version of the Keihin, with a pressed-in tin idle jet that is quite awkward to service.

That is a basic outline of what I don't like. I see it as having been made as a throwaway engine for residential users, who are satisfied if it runs well for a few years. There is a market for that, but I don't admire the approach.

Grumpy do you have any pictures of the internal of a chonda. I'd just be interested in seeing what it looks like. Incase I come across one.

I don't have any internal chonda pics, blumbly. I've seen a few, and they look identical to a real GX or GXV Honda. Most of the parts are interchangeable with Honda ones.

Well grumpy ,though I had got one but it turns out the shaft size dosent match . This is the mower I got .

They match up in circumference the original a little taller but not a match sure what brand of engine is on this . 1P64F5Y25585. Never mind I will come across one I hope.

That is interesting roebuck. Can you just change over the crankshafts as well?

I wouldn't like to do this because it isn't mine but I'm going to ask what might be a silly question . The new Flywheel shaft size on the bottom is the same as the original but the top shaft size is slightly smaller so it wouldn't be practicle to drill a bit out of the top about a mm? So that it could drop a little.

No it's a silly question I'll just wait till I get another to suit either gx/gxv 160 thanks for your time.

I haven't understood the question yet roebuck. Is the taper the same? (Will the new flywheel sit on the taper and lock onto it when you press it down, with a large contact area?) Is the problem that the new flywheel has a smaller bored taper of the same angle, so it sits higher on the shaft?

It is essential that the taper has the same angle as the original, so if you put blue on the shaft, then carefully sat the flywheel on it then pulled it off without moving it, you would have close to 100% blue transfer to the inside of the flywheel's tapered bore.

Fits on nice but just won't go dowm far enough. It has the same taper so no point in drilling . They are not the same diameter across the bottom.where as before I said they where my error.

I'm slightly surprised they have made the diameter different - I don't see what the point was. However the outcome is that the flywheel won't fit on the crankshaft you have. Did you take a look at the magnet in the new flywheel, to see if it is the same except for not being broken?

Grumpy the magnet appears to be exactly the same size. 3 pics the first one of the flywheel with the original magnet plate just sat over the other . The second pic the Flywheel with good magnet in it . The third with both flywheels underneath side faceing up. Idont know how to go about getting the good magnet off as it looks really well glued.
