hi Norm, and sorry mate, the issue with that motor running in it's
present state is the bore, in that condition, it wouldn;t run if you plugged
Hazelwood into it....so until that is addressed, your wasting your time,
sorry LRT, all the other swapping around is not going to gain you a thing.

Caleb, I just remembered that the early impulse barrels here will not fit the plastic carby. You are overthinking the whole thing. What is it you want to do with this mower, use it for mowing or wanting to restore it to original. And squizzy I wasn't planning on plugging it into Hazelwood, because once this mower is running again, it will be running much longer that Hazelwood will be

Norm,

The owner only wants it to use it to cut grass so it doesn't matter if it isn't correct from a restoration point of view. It can have another engine as long as it fits the base. This may be a better option in light of the crank being bent.

I've got it to run a few times and in its present condition it even leaves the Greenfield ride on for dead in the rough. Not to mention a four stroker!

It just would be handy if it could produce a spark on every revolution...

LRT, you ignore the basics of mechanics at your own peril...
and Norm.....they both could be lying idle for a long time!!
hahaha

Yes you are right that you need good compression for an engine to start and run properly.

However, the main problem with this engine at the moment is the spark cannot jump a plug gap more than 6 thou in the atmosphere with a dry spark plug. Until the ignition system is fixed it's not really worth rebuilding the rest of the engine.

As I said I have a few sidepull motors here, I haven't looked at them but I would expect they could be got running without too many issues, I just don't have time to bother with them at the moment, too busy fixing powertorques

Thanks Norm. Caleb

Thanks to Norm's helpful advice and supply of a rebuilt engine, the Victa 550 is now 'turning grass into lawn'.

With Norm's carby modifications, it now has proper throttle control and starts with one gentle pull. The owner is delighted.

Diagnosing this faulty mower engine was a challenging experience to say the least! I have learnt heaps. My thanks to everyone who answered my many questions.

Looks good Caleb, glad to be able to help keep a real machine like that doing what it was designed for

That looks beautiful!! Shiny motor on a base with character lines is actually a good look and ready for work!!
