Maybe just one to try them Norm. See if you can fit it to a Super 24. Super 24 's are worth a bit more and with a brand new engine might be attractive to a contractor or heavy user.

As you are close to the supplier, the freight is not an issue. That's what has been holding me back. Also they are a clone, maybe not as good as the original.

The one you have does it have spark & compression? Fuel is usually the issue with them I'm told.

All the best
Jeff

Yes Jeff the supplier is only 5 mins away, I'm just not sure how rugged they are compared to the 160 cc Victa as the Iron Horse is only a 125. I will wait till he drops the price back to $100 before I get one. His price goes up and down all the time. The Suzuki I have has compression, and the spark is very fine and blue , I would like it to be a bit digger but as I don't have another coil to swap onto it I can't check. Can't get the slightest puff from it with starter fluid so I figure it might have been straight fueled

Hi Norm.
I recollect hearing unkind comments about the quality of the Iron Horse

The Pot Metal Horse??
Still, might be worth the punt.
The original Suzi M120X weighs the same as the full-crank Victa (150 gm less on my scales).
Worth pursuing fixing your original? If the bore/piston scored from straight fuelling, nah.
So fuelling is mostly their weak area.
Not just the difficulty of ultrasonic cleaning of the original gummed up Mikuni carb, the throttle spindle can wear the carb body too.
The Carbie Doctor is selling Mikuni substitutes on eBay for $40 (eBay item number:331786948199), free postage.
Pricey, yes, but maybe worth a go?
It might be cheaper in the long run than fiddling about adapting Chonda carbs as some folk have attempted in the states.
Just a thought.

Thank tortise2 and wecome to the crazy place. I know all about the Suzuki carbs, I struggled with one for far to long and gave up on it, just couldn't get it to settle on the governor. I have no shortage of 2 strokes, it was Jeff up in Brisbane who was struggling with the early F/C bits and he thought that putting a new Iron Horse on his 24 inch might be an option. It is quite a difficult fit as is a Powertorque on a F/C 24 inch base. We have had many discussions about it

Hi,

I have the 24 running with a PT on it now. Seems OK but I would not try it again. Took forever. I'll post some pictures as soon as I work out how.

All the best
Jeff

Jeff, I know exactly what you have gone through, hours turn into days very easily. Glad you got it sorted in the end. One thing with the Iron Horse motor is the exhaust does not become an issue

Thanks for the welcome NormK. I think I might get one of those chonda carbs & see how it goes on a Soozi M120x. (Rover base)
Will post up in another section if any good.

Hi Tortise, be careful not sure what the difference is but 2 stroke carbies are usually different to 4 stroke and I'm not sure if the bolt pattern is the same, the Chonda is offset and I'm not sure how the governor would work and then you have to be careful about the choke, cable or manual operated. I will have a look at a Suzuki this afternoon and see what I think. I have a Suzuki here that I can't get to fire, it might have been straight fueled

Hi Tortise, that is a no go, the Suzuki as I thought has the holes level, the Chonda is offset.

Thanks Norm. Perhaps if the Chonda carb is offset, then my assumption that it would be the same as fitted to original Hondas is wrong.

The sort I'm thinking about modding is a copy of the Keihin 16100-ZOL- 013 (replaced by-023). Fits GCV135/160, HRU19R (and D),&HRU216.
Price varies from about $12 to $20
Mods required seem pretty minimal. Extend body mounting holes with round file to match suzi studs, drill breathing hole in airboxcover and mounting plate to match with new carbs idling circuit, cut/file off any interference with the new choke actuator plate (plastic). Governor/ throttle plate should line up with Rover's throttle cable and governor arm spring setup.
I've been looking at the work done by a member of an american tractor forum. Google "The Mikuni to $14 Honda Carb swap", My Tractor Forum.com
Lots of US Toros and Flymos used the Suzuki engine- all eventually develop probs with the mikuni carb, and at $140 replacement?
Sorry if I've misled you, but looking at what you've done with/for Victa's G4 and LM carbs, I think this might interest you.
I was thinking of mounting a spare suzook engine to a FC Super 24 too. This thread suggests I think about something else.

Hi Tortise always interested in getting /modifying anything to get things working again, I like the Suzy motor but the Mikuni on these is a dud. All the Honda vertical shaft I have worked on from memory have had the offset carby studs, that is not to say they are all that way.To me the simple way to set up a F/C 24 is to hunt up a F/C motor and rebuild it, cheaper and a lot less work that trying to fit a different motor to it

Gd'ay folks,
Oddly enough, I'd say that the reason this carby was a major failure point on these engines, was that it was too high-tech for its application!

Near motorcycle level design technology , with too many small diameter fuel galleries, which are prone to blocking by fuel gum formation.

Most probably the cause Gadge, difference with a motorcycle is it has a twist grip that gives it throttle to control , from what I have read about the Suzuki on the Rover the governor, obviously there was a problem with that part of it

I have always been intrigued by these engines. Has anyone used both these and Victa 2 strokes often enough to make a call on which were the better engine to use?

I have also been intrigued by them, have started a good running one before and went 2nd go and ran smooth.

Getting one on an alloy deck Rover chassis is on my to do list - along with a briggs komatsu 2 stroke on alloy masport deck

I have a few of the Suzuki motors here, I don't waste my time with them, motors are probably ok but not worth messing with the carb on them. I did have one a few years ago that was running, but hunting.It ran smoothly, I'm guessing because the motor is mounted north/south it helps with the smoothness

Thanks Norm,

A mate of mine from work has a really good nick Rover with one of these suzuki engines, and he has always said it is better than a Victa 2 stroke. Having never used one, I have no idea. I told him when it lasts longer than 40 years, give me a call. Mind you he has offered to sell it to me, knowing I am a 2 stroke advocate, and the mower itself is a nice looking unit, well maintained with an alloy body. But asking for over $200 I thought was a bit rich.

Hi Sapper,
The one I had I sold for $20 it was in good condition with catcher but the carby was hunting, I had tried to fix it but couldn't get it right. Apart from that it ran smoothly and cut well. I think your mate is dreaming a bit. Stick to your Victa 2 strokes, still plenty about to be had for $20/$30, just needing a bit of maintenance

Hi Sapper, NormK and Tyler,

I found a Rover one and couldn't get a peep from it so has been gathering dust ever since (3 years).
I have heard them and they sound like any other two stroke to me. I just like having one in the collection.

It might "run" nicer than a Victa but that's a moot point if it's giving trouble. A Victa will tackle jungle growth and lawn just as capable and reliably.

Hi all,

This info from tortoise2 will get them going if you have carby trouble https://www.mytractorforum.com/threads/the-mikuni-to-14-honda-carb-swap.255222/
