Qualcast Rotavator Cultivator Refuses To Start | Lets Find Out Why

[@alandykes2519]

Fantastic Martin you are one clever guy gary can scrap the old engine now 👍👍👍👍

[@retrorestore]

Thanks 👍

[@butler386]

Excellent fix for the rototiller. If you change the belt on the pulley it will increase the rpm of the tines a lot. It will dig better but will give the operator a better workout. It will make a man of Gary. Great job. Thanks for the video.

[@davidthehillbilly7995]

That Honda engine has a gear reduction output. The poor tiller is only seeing 1/3-1/5 of the RPM it is expecting. It will do a much better job with full crankshaft revs if you have another engine without the gear reduction box. You will need to redo your mounting and push the engine rearward since a non gearbox engine will have the output shaft 2 or 3 inches closer to the front of the machine....

[@retrorestore]

I just need to speed the engine up.

[@andrewwitham5405]

The Honda has a 2:1 reduction box. The PTO won’t be turning fast enough for the tiller.

[@andrewwitham5405]

retrorestore you can’t speed it up enough. It would need to run at 7200 RPM to compensate for the reduction box. The engine will fail at around 4-5000RPM.

[@retrorestore]

@@andrewwitham5405 We'll see, I like to break the rules.

[@rabsrealm]

The knack with a rotivator is to pull back on it slightly while it rotates. That way the teeth get a deeper purchase on the soil. :)

[@retrorestore]

Thanks for the info!

[@barbarawiddowson635]

There's a lot of people with a lot of knowledge on this channel.Me,I know nothing other than I enjoy watching your channels Martin.Stay safe.

[@retrorestore]

Thank you Barbara.

[@philiphutchinson4210]

Hello Martin, I discovered your channels a few weeks ago and I have binge watched them since. I am too old and the wrong shape to climb under cars etc. but you have given me great entertainment. It has been a pleasure to watch the trials and tribulations of your rise in the KZbin world. Your family gatherings and the love and loyalty shown is wonderful to see in this day and age. There is not much in your content I do not watch. I did enjoy watching the reruns of your live streams and it literally made me shed a tear when each of your dogs passed. As a dog owner myself I understand your sadness. Sorry to drone on but I thought I would just let you know how your "adventures" have given me pleasure. Much love to you and your family and I think of you often when pottering about in my sheds and garden. Phil.

[@retrorestore]

Hi Phil, Thanks for your message bud and glad you are enjoying our channels. Its nice to know there are still people about who have the same values as us. All the best. Martin

[@garymucher9590]

Martin, here in the states we call that a rotor-tiller. And you don't take any wheels off for them to work. Your engine is not transferring the power to the belt/gear assembly correctly. When it is working properly, the cultivating tines will spin a heck of a lot faster and dig in without effort. Been there and done that many many times. You need to dig into it more to see what is not working properly yet. Thumbs Up!

[@adierob1]

Ive looked forward to watching how you got on with the cultivator.just got in and sitting watching with a pizza and chips and martin ive got to say only you could think of taking a file to the spindle to make it smaller!! Top class and well done, thoroughly enjoyed watching.

[@retrorestore]

Thanks Adie, glad you enjoyed the vid bud.

[@andrewkelley309]

That's a brilliant job Martin , proper retro fit of the Honda engine . Before you menchened using a file to grind the shaft down, I already thought you were going to do that . It's amazing what you can cobble together with a bit of thinking. .👍👍👍

[@retrorestore]

Thanks Andrew.👍

[@normsmowers4758]

Cracking job Martin pure Guinness

[@imiles5548]

the speed reduction on the engine as to slow as the old engine was direct off the crank shaft.

[@jamesgame8573]

Martin, I have no idea how you find the time to read all these comments but this one from me after viewing your content for some time and the content of a number of other leaders in the rebuild/repair/discover field: This was a really impressive video and immediately stood out by not only the quality of the production but more so by your fantastic way of describing to the viewers what it was you were looking for and what you were doing to sort it out, brilliant! I know it will be difficult to continue to produce content of this quality all the time but I'm sure if you do then you will be admired and watched by so many of us out here in the land of people for whom mainstream TV offers nothing to interest us.

[@retrorestore]

Thanks James, that's kind of you to say bud.

[@DiecastPowderCoating]

That's great Martin, I would have given up and chucked it. You persevered and now have a great machine. Well done. Take care, Jeff

@@retrorestore it's just refreshing to see you look at things from an engineering logic way like I was bought up with . 👍😉

[@cabdriveruk]

Great video Martin. That old engine has had its lot. Seems like the honda needs a lot more revs to spin them blades around.I don't think you have to remove the wheels , just raise up the bar the wheels are on with that lever. Cheers, Jeff.

[@retrorestore]

It was just the first test run Jeff. I'll sort that out.

I have this rotorvator my pap brought it new in 85 86 just changed coil on it due to no start and she runs but faster that what your is no prob triple speed although my blades spin all the time and handles dont seem to be working properly lovely to see another one the same

[@berndb.5097]

A few people would surely want to play with that. I would recommend that you put up a poster in front of the house that says "Play 30min. In the garden for only 2 pounds" ;-) Good work Martin !!

[@alanlake5220]

Good video Martin, If you have to grind in the valves, you need to check the valve clearance , 6/8 thou, as the clearance will tighten up from grinding them in, so you adjust the clearance by grinding the bottom of the valve stem .

[@retrorestore]

Yes I know Alan but these valves were shot.

[@andy_v4443]

excellent, deffo keep it, could have very good vegetable patch

[@sharky09000]

That suffolk engine is the same as om my suffolk colt mower but you done better by putting the honda engine on it great job martin

[@retrorestore]

Thanks Roy, yes its handy I had an old Honda engine to use.

[@lambyjb0555]

Decent rotavator, good job!

[@staind288]

Martin, you can actually adjust valve clearance on these. If they're too tight you can grind small amounts at each time off the stem

[@retrorestore]

Yes I know that but these valves are shot.

[@classicgamer4451]

Wow those valve's have a bit of movement on them a scrap engine then what ashame what you can when you have the right things to hand i do love when thats happens nice one Martin 👍

You deserve a great many more views than you are getting. Although I do wish you would avoid the WD40 when you can.

Yeah, the old engine was nothing but scrap, and you never go wrong with a Honda engine - they're almost indestructible - but you need to increase the rpm and the speed on the tiller - it's going way too slow. Great video.

you're a genius Martin

[@petepeterson4540]

watching your video on the 30th

[@forevercomputing]

Ideally, the output shaft on the engine should be left alone and modifications should be made to the pulley. Replacing the crank on the engine is more work than sorting a new pulley.

[@retrorestore]

That's ok in an ideal world but I needed the job don with what I had to hand.

[@malics69]

first class job works

[@terryatkinson899]

Nice one, let's see how much you can rev up that engine to make it rotavate better so the engine isn't labouring so much. Maybe that's just me but I like to give it the beans.... youd need some type of claw behind to stop it running away from you. No need for the gym after using that.

[@staind288]

There is a nut on that throttle lever. It needs tightened to be used in this manner, loosen (like it is) for a remote throttle and linkage

[@retrorestore]

Yes, I'll sort it. This was just its first test run.

[@alandavies2122]

Great 👍 job

[@retrorestore]

Thanks 👍

[@69Phuket]

Happy days! ;)

[@kylepaluzzi4176]

There is actually an adjustment for the valves he grind a little bit off the stem to get clearance and if you have too much clearance you can Weld the ends of I'm and grain and flat back to the clearance that you need

[@kylepaluzzi4176]

Grind

[@retrorestore]

Yes I know bud but I meant no adjustable factory adjusters

[@retrorestore]

Yes I did Luke, I have an original engine from a local subscriber as well.

[@slimshady6718]

The Honda has a reduction gearbox fitted u should have removed that first , this is also why the engine didn’t line up as the out put shaft is in a different place , take 2 should be u removing it and it will be better then as the blades will be spinning 1-1 revolutions

[@harryburford6629]

the one that came off. IF you did the work on it would be a good relibale spare for you always ready to go

[@retrorestore]

It needs money spending on it Harry, I may visit it in the future but I needed it working asap hence the transplant.

[@dodgydruid]

2:52 chucks down the roll of lino and some chalk for a bit of a northern soul...

[@matthewharmer1656]

Wrong engine,cause it's got a reducing gearbox on it!! It's way too slow,just imagine doing an allotment at 1/3 speed,crankshaft needs to spin at 2500 rpm min,... apart from that it's a great video,well done.

[@retrorestore]

I can speed it up.

[@matthewharmer1656]

You could increase engine speed, or change the crank pulley size ,but it still wont be the right speed, might be good enough though, I was a small engine/ plant fitter for 20 years, my self I would put the correct engine on, still I really like your videos. Cheers

Depending on the age, it might have contact points fitted.

you could fix the old engine just some valve guides and some ringes you should show how it's done watch TYREL FIXES ALL it would go for years you have a good chanel it would make a good video you should never file down cranksharfts they are a set size for a reason not trying to be smart thanks harry from N Z bye

[@retrorestore]

Harry, Its a matter of getting over a problem with what I had available. I own the scrap Honda engine and it cost me nothing. It now has a new lease of life. I never say never, there's always an exception to the rule. I don't like to live by rules so I break them now and again. When you say you should NEVER file down crankshafts, In the real world with what I got available, I got it working. that's not what I would do for a customer but its my stuff and I needed to get it working for the weekend. I succeeded.

So this evening's video is a bit rough n ready bloody Samsung grr grr, would help if I hadn't been tucked up with what was supposed to be an Ixus 5... what I got instead was an Ixus L.1 inside an Ixus 5 box, was so cross and the seller has closed their account so no refund for me :( Gonna just buy a go pro this months PIP and sod Canon and Samsungs, may their executives develop incurable rectal complications that itch like a bit...

[@dodgydruid]

Ixus L.1 btw is a film camera which is a LOT of use for a digital setup... Wished I had me mums camera's, after leaving Fleet St she went into films and tv screenwriting and made some docs for Channel 4, she had some very expensive ex BBC stuff that recorded direct to a Betamax cassette, had to be a Kodak one as well for some reason but it came with its own portable studio for mixing, editing, dubbing, live and recorded inset's and it weighed a ton but the clarity of it was majestic. She had for audio nothing but Uher reel to reel and a super expensive Sony mic she was given when she was at LBC.
