It was worth a try. If you find another PT 24 I reckon it would be worth trying to get one which obviously still has the original engine Just to see if their is anything in this special motor or flywheel or anything else
I can not believe that Victa would have sold machines like this for many years with such an obvious problem. They would have been driven mad with warranty claims.
We still love our 24 but if a late model original one came up close to me I would be tempted.
I have sent the link to my brother to follow up. I am not sure he will as he the reckons the smaller utility handle tank is good for his yard. Almost a full tank every time he mows. Probably is best as keeps the fuel fresher.
I wonder if that guy wrecked a Super 600 He might have other bits that we need more. Like a spindle, a genuine belt and the proper pulley for a PT. Can not see a way to contact the seller.
Hi Jeff, I got in touch with the bloke and he had everything except the body but what he wanted for the remaining bits was twice as much as I would pay for a complete unit
Another dreamer. He may come to his senses after a while Market is pretty small except for people like you and I. I do not need anything urgently so will wait for a PT 24 non runner Must happen one day.
Ok so back to this slasher again after it has now been straight fueled. I am fairly convinced the PT motors are not a patch on the full crank motors. I pulled a PT off a base I had running a few days ago, put it on the slasher and now can't get a kick out of it, this is not the first time this has happened and I'm convinced it has something to do pulley/big blade carrier. I know this defies logic but this is what I am finding and to me these fitted with a PT are not a patch on an F/C. Every one of these fitted with PT's I have been involved with are always problematic. Problem is I don't have enough bits and pieces to convert them over to F/Cs. The other problem is this one belongs to this blokes father and he didn't tell him he had borrowed it and his old man loves his slasher and would be very annoyed this has happened.
Ok just proved my theory, I pulled the PT back off the 600 and put it on a standard 18 inch base and it started first pull. My belief is that the half crank flywheel design is not good enough for this purpose. I know that it has a big spinning mass in the belt and big blade carrier but I don't think it is direct enough to help them initially fire. I will not bother with PT's on these again.
Put another good running motor on it and same result, so that is the end of it, not wasting any more time on these, they are a dud, probably why you don't see many of them around.
My brother loves his 24 converted from FC to PT. It's mowing half an acre of vigorous Kikuyu. It does Ki K back at times but he is used to that and can cope
It's a bit heavy to push up his fairly steep hills

I wonder if belt tension is an issue. A,very tight belt makes it hard to pullover. I know they can be too loose but I think too tight is just as bad. Jeff
Hi Jeff, I am completely stumped with these, can't remember how many I have worked on and everyone of them has caused major issues. Belt tension is not the problem and on it at the moment it only has the spring tension that sits in front of the motor on it. This one here at the moment is the one that was kicking back savagely and I eventually fitted the decomp with the restrictor and that solved the problem. On the 2 motors I fitted today I used that same decomp valve, might try a different valve in the morning and see if that gives me kickback. That is about the last thing I will try on it, I have already told him I can't fix it and to come and pick it up. It is in good condition bodywise, but just fitted with a motor that is not suited to the design
I sent a good sidepull fc with the 24 when it went to Eden He sees no reason to change back yet. It would be easy to do we have the sliding plate just no tensioner assembly.
If he ends up wrecking I would be interested in parts or all of it. I need a blade carrier ,a genuine belt and a spindle would happily take the whole thing but how would we get it to Eden.
Hi Jeff the PT pulley is very simple and I'm pretty sure that they could be used on the F/C's as well. This means you don't need the taper pulley they fitted to the F/C's, just leave the boss on and bolt the pulley up using the standard washer and nut. Might have to adjust the motor up a bit to compensate What diameter is the aircon pulley? If I am going to have to fit F/C's to the later bases then I will need to get a number of adapter plates laser cut because it is too time consuming making each plate by hand. Now I am really on the hunt for as many F/C's as I can find I wonder if these pulleys are still available they shouldn't be too expensive, they are only a pressed metal one, like an automotive waterpump pulley
That certainly is a heavier one. What is that off?an edger or something without a blade disc. I wonder if it would help much as there is no weight out wide like a blade disc. I have never seen one like that
In my case, not sure about Norm's we are not using an original PT 24 engine Maybe the real engine has something like that even a heavier flywheel as we have talked about before
I'm sure the kickback is an inertia problem If you switch off the ignition no kickback so the engine is definitely trying to run backwards. My scenario is that because of the belt etc the engine is hard to get turning properly and it stops on a compression and unfortunately fires as the piston falls back hence the kickback.
More weight under the engine might help even and ordinary blade disc if it would fit without blades. You could then leave the belt looser.
We give ours a hell of a pull trying to get it it to turn properly. The PT starter really locks on to the crankshaft and won't come off easier like a full crank.
A heavier mass on the crankshaft carries much more momentum this momentum helps to keep the engine running at a steady RPM as you add load to the motor.
This heavier mass will help to spin over a higher compression motor when starting.
You could also try lowering the compression with a decompression plate and 2 gaskets and see if that helps to spin the motor over quicker so it doesn't kick back but you may loose a little power .
