Any reputable garden machinery dealer should have a proper tester , try to go for one that’s been in buisness for quite a while , most modern upstarts know next to nothing about coils and condensers.
Spitting and banging is quite often incorrect timing thoroughly check it.

Couldn’t get that link to work , first and foremost would be to get the coil and condenser PROPERLY tested , and by that I don’t mean wasting ones time with a multimeter.

I’m fairly certain that is a variant of the 4/5 Carb , which was unique to Atco(I’m not 100% on that , but have never seen it on any other machine)
It’s a very simple carb to work on and get clean , which leads me to suspect you have an ignition problem , either timing , or coil/condenser failure.

To me it looks like the drive system from a Ransomes Multimower.

Nice to see another machine saved , and going to use. It’s only the modern Howard orange that is bright , originally 350s had what I would say was a semi-gloss finish.
George at Villiersparts did have some ID plates , worth checking if he has any left.

Before you go about removing the flywheel(which will involve re-setting the timing) , just remove the circular brass points cover and thoroughly clean the points , you may just be lucky if it’s been standing awhile that the points have a covering of corrosion. This can be done without removing the flywheel.

I would agree with Charlie , only my personal opinion , but I think it is ridiculously overpriced , as has been said carefully no mention of any issues , or whether it actually runs.
Having said that , it is ultimately the current market and what some folk are prepared to pay that controls prices. Due to recent events with more people going into growing their own prices of all types of garden machinery have hit very high “false” prices , and I suppose we must understand some are seeking to take advantage.
Unless you have heavy clay type soil that really needs ploughing and standing over winter , I would just settle for a good quality rotavator.

From memory there are 5 positions , it should (as a starting guide) be in the 3rd or 4th grove try it and go from there.
One point I have overlooked , is the manifold butterfly free and working.

Steve , there is no main running jet , adjustment is done by altering the height of the fuel needle , slip the holding circlip out and lower the needle by one notch.
Incorrect timing will cause poor running , but we must try to help you eliminate one problem at a time.

Before you even think about removing the flywheel , THOROUGHLY go over your carb again , check the jet and its passageway in the bottom of the float bowl , these have a nasty habit of corroding badly. The mixture jet is for tickover only , main running mixture is achieved by raising/lowering the fuel needle

Geoff , one tip , make sure your horsemuck is at least three years old , IMO using “fresh” horsemuck will do more harm than good.

From the last photo I can see alot more clearly that you have seen the bolt I mentioned , I was almost certain there were 6 bolts holding the sump on. Yes, I’m almost certain the roll pin just drifts out.Once you have split away the sump , and split the big end you will be able to see/feel what if any damage has been done.
Report back as and when.

Andy.

[andyfrost]

Check the recess hole positioned between 3 and 4o,clock , from very distant memory the sixth bolt is down inside this hole……..it’s many years since I had one of these apart , so I stand to be corrected.

Are we talking of the small engine(around 3hp) as fitted to some Howard Bantams , if so I have one laying in the shed doing nothing. I’m not overly familiar with Kohlers.

Alan , one springs to mind among many opportunities , it was a large Ransomes cylinder mower at a posh country hall that my uncle worked on, it had started to become unreliable , I had the chance to buy it for next to nothing.
At the time it was the oldest petrol mower that I had seen , powered by an
“Orwell” dry sump engine , I did see another at the Ardingly vintage show a few years ago.
