Yes if i tip some fuel down the carby inlet (where the air filter is) it fires after 2 or 3 pulls of the cord. From then it runs fine and now doesnt stall. Thats the only way i can mow at the moment otherwise i would be pulling the cord until sunset...

And that is probably what you will have to accept, motor is probably a bit tired and not creating enough suction to draw the fuel up on start up. This is why the primer setup was so much better

Fair enough. I am half thinking of an engine replacement down the track, does anyone know what make is best for a replacement? I found a briggs that will swap straight over but is it worth going to a honda?

Hi Mb,

I guess it's up to you on that one, it all depends on how much you want to spend. There are plenty of Chonda's available for around $130~140 on eBay delivered so that's a pretty good option. Only thing is you'll have to change your clutch body to a 19mm unit as the 3HP Briggs you've got has a 5/8 shaft along with it's clutch half.

There are new Briggs slopers around and as you have the model with the lower kinked handle bars you can fit one of those straight onto the chassis, but those again are generally a 3/4 (19mm) shaft and will require the new clutch body.

Honda in my opinion are just way too costly and if you buy a Chonda and do regular oil changes etc. there's good life to be had out of one of those.

It's your call I guess.

Cheers,
BB.

Thanks very much for the advise BB. I have found a 2.5hp briggs for around $280 that apparently will fit straight on. It comes with 2 options on shaft sizes. See how i go. Cheers

Sorry it is 3.5hp not 2.5

Hi Mb,

Around that figure sounds about correct as the Briggs engines are somewhat more expensive than the Chonda's, but in saying that they are no better in my view and still idle quite roughly which is not what you want sitting on a twin rail model 45 that suffers from rail fatigue rather badly if not kept in check.

Cheers,
BB.

stupid question.... i have never heard of chondas before and I can't seem to locate any on ebay...
Any links?

Chinese Honda copies we just call them Chondas. Just ebay horizontal shaft motors and you will find heaps of them

that's what i thought... thanks

Hi Guys,

Sorry for the confusion, I thought everyone knew what a Chonda was, seems I was wrrrrrrrrrrong.

I'm just about to buy a recoil starter assembly to get one going that I have sitting on a 20" Scotty. Honestly at the price the whole engines are I'm starting to wonder why I'm buying the starter. I guess I just can't get my head around disposing of anything that still works and very well I might add.

Cheers,
BB.

Thanks BB, i found some online. To me it comes down to being comfortable with a "guarantee" that this will be a straight swap onto mine... I understand there are 2 shaft sizes to be aware of however not sure i feel right buying a chonda without exactly knowing it will fit. There are brief measurements on there ebay listings however one of the suppliers for the briggs was able to check the model number of my current engine to confirm their latest briggs will fit with confirmation in writing.

Hi Mb,

If you buy a 5.5 HP TWM Chonda that is being sold for around $130 to your door on the bay you'll find it will fit straight on.

The only thing is they come with the 19mm / 3/4 inch size shaft only. The base sizing is all the same industry standard along with the height from base to centre of shaft. If these were different they'd never have sold the millions that they do as the fit is universal.

Cheers,
BB.

PS. do not buy anything higher than the 5.5 rating.

Ended up fitting the new briggs and stratton engine, went straight on with no issues. Just a minor adjustment to ensure the clutch was engaging correctly,l with tightning the screw on the clutch lever. Very happy with how it runs.

Also fitted the new bedknife after it got sharpened and it cuts a dream
