Hi John, and welcome to TGMF. I  think it's a Villiers 150 lightweight vertical shaft engine. Give that a Google and see if you can find someone similar.

Sorry 40jack, I totally missed this post somehow.  

I believe you can use the right hand one in place of it by turning the ratchet pawls around the other way.  Or get a ratchet assembly from a later model such as a HR 194 they should be the same.

Hi, and welcome to TGMF.

Is there any way you could attach some photos of the machine and perhaps the parts you're struggling with. That might help to work out what make and model it is.

If you pop the jet module out of the carb and look at the end of it where it goes into the carb, if you see two brass jets it's the old one. If you see one it's the new one. See attached images showing both old and new. Part number (596521).

By "slight surge" do mean the engine is hunting slightly, as in revving up and down? 

It's usually caused by a slight blockage to one of the jets. Make sure if it's a older model that it has the correct jet module fitted, and replace if necessary.

You're welcome.  It's good to hear that outcome.  The new top pulley half of the bbc is made of a less brittle (copper infused) material so should hold up without issue.

I would say the dogs have lost their edges in the gearbox, or the clutch arm has broken, usually due to worn dogs, or a bad (stiff) clutch cable.

Anyone go to SALTEX this year? Was it any good, and did you see anything of interest?

No problem Kevin, I just created a board for tillers / rotavators and moved your post to it. That was entirely my fault. ;)

Weak clutch springs, or idle speed too high perhaps?  I've not looked inside one of those for quite some time to be honest.

Don't think I've had to actually change one of the drive belts yet, other than the bbc one. I would probably just remove the clutch to check it, and change the belt at the same time if required.

Is your belt worn then Greg?

Steve.  It definitely has a problem then..  I'd be looking at the bbc to see if it's starting to fail, the A spec ones do and they were getting replace under the Hayter warranty and now top pulley half is made of a copper infused material which is less brittle. 

The old A spec ones you can normally tell when they're starting to let go because the machine will develop a rattle as the top half breaks loose. This can make the actuator arm move back and forth rapidly, and either cause the cable failure, or even make that spring saw its way out the side of the locating hole, like the one I had a few weeks ago. As you can see in the image below, the hole at the bottom where the spring is supposed to go. ;)

A bent crank can also cause this kind of thing .

I haven't modified one, to be honest we just change the plastic jet module for the latest one if required. Some had the wrong jet modules fitted, but as this is a new machine I'd imagine it already has it fitted. 

The carbs are very basic and simple to work on as you said, and yes the screw head sixes are annoying at first, but you get used to them.

Make sure there is good flow from the tank when the fuel cap is on, had some that don't breath properly and act like a fuel tap. Also make sure the little brass jet on the left side of the intake is clear.

Hi Steve, and welcome to TGMF.

Quote from: steve potter on October 26, 2021, 09:21:37 PMand last week the bbc cable spring snapped at the connection point under the blade.

This should be covered under the warranty, it's not your fault the spring broke, unless you have over adjusted the cable..  Seen this a few times and can be caused by a failing BB clutch top pulley half.

By the way, just wondering, if the machine is brand new, then why doesn't your friend contact the dealer he purchased it from and get it sorted out?  Messing with it yourselves could screw any chances of getting it fixed under the warranty.

The spring pulls the choke on (closed), and when warm the rod pushes the choke off (open).

In your photo above for example the choke is in the on / closed position.  Ready for a cold start.
