I'll move the shim as suggested.
I guess Mr Victa never imagined in his wildest dreams that we would still be using his engines 50 (+) -years down the track so shaft facial wear was resulting and float was never envisaged so was never added to the repair manual.
Again, brilliant reply mate! - It perfectly addressed my issue,

- Bumps

I saw a while ago someone fixed a broken primer by picking out the old rubber primer and then they used a whipper snipper
clear primer but from memory they had to jam a big O ring in to hold the primer bubble in tight. Otherwise most people just buy
a new primer cap.

I don't think the fuel tank / top cowl is correct as it looks from an earlier model ,the parts list for 1999 on shows a later top cover.

You must be using the wrong rope or you must have big shoulders if you can break a cord on one pull

If you have connected the wiring up correctly it should run but if connect incorrectly you will not have any joy.

Take a close look at the paper in the image to make sure that you have everything correct also you need to run the wires from th module under the e plate otherwise you will have issues because if they get to close to the magnets in the flywheel they could rub and the earth out.

Try doing a check and give us an image with the wires connected to the module which should be two.

The muffler on the Victa 18 just uses one bolt to hold it on ,eBay sell the correct gaskets ,they are a thick gasket,
sometimes the alloy on the muffler is warped where it bolts onto the port and they won't seal properly also check
the end of the baffle is blocked as you get a lot of rusted out baffles.

As you tighten the bolt on the side of the barrel you need to push the muffler towards the base so that gasket can
seal.

There is a metal plate under the alloy base and that gasket must be sealing also. It's not uncommon to find this
metal plate cracked and leaking.

I am still new to old Victas and repairing small engines so I could be wrong. I have had the same issue on my Model 5 too and after taking the head off I found the cylinder had a decent cavity that lined up with the Carb side transfer port. It has run roughly on starter fluid before I noticed the backfire and then the cylinder. My idea is it can create compression to a degree however you can see when pull starting it there is a draft exiting the carb. I'm currently in the process of swapping the piston so I'll update if that solves my problem.

Cheers, Xav

You will have to connect the vacuum line into the manifold if you have enough room, otherwise you will have to drill a hole into the carby throat just before it enters the manifold.

Before you buy and replace a diaphragm or O-rings, before you cut or change any carby springs, and certainly before you file or drill any plastic carby parts:

1. Attach a clean hose to the vacuum nozzle, where it emerges from the cowling around the engine cooling fans. This plastic nozzle normally has a short hose that runs to the carby and moves the diaphragm (and attached poppet valve) up and down to govern the engine at the correct speed. You need some tubing of the appropriate internal diameter (~5 mm). About 60 cm long is convenient.

2. Blow or suck on the tube. If no air passes through, there is a blockage, probably in the small hole that sits between the cowling and the cooling fans. If this hole gets blocked, the engine / fan can not create a vacuum in the hose to the carby, so it will not govern engine speed.

3. You can try to clear any blockage with compressed air, if you have it. Or you can try to clear it by poking a thin wire through the nozzle. It needs to be thin because the hole inside the cowling is small - less than 1 mm. Even then, you will need to line up the centre to ‘pot’ the hole. If this works, the thin wire will continue into the space between fan blades. Then you should withdraw the wire, re-attach the vacuum line to the carby, and try the mower.

4. If you can not clear the blockage as above, it is possible to remove the nozzle (Victa CR03727A) for cleaning, but you will have to remove the mower base plate and engine to replace it. Still a DIY job, but not so easy.

5. If there is no blockage, the carby diaphragm may by faulty or one of the O-rings may be leaking so the engine runs lean and fast. These things are covered in other posts. It is cheaper to run simple diagnostics before replacing parts. (eg: does the engine slow if you attach your clean hose to the carby vacuum port and suck on it? - if not inspect the carby diaphragm and reseat it carefully.)

This is a common fault that is easy to check and fix. For some reason (no parts to buy?) it is rarely mentioned. Some people just replace things then give up and run the throttle manually.
