Husqvarna K750 concrete saw

[Fatboy2017]

Good morning,  I acquired a Husqvarna K750 concrete saw in with a package of saws all none runners. All saws are up and running including the K750 which was low on compression suffering from usual lack of maintenance, filters complete trashed or missing and air deflector missing so ingested dust and poor cooling causing a partial seizure. All rebuilt and running well but somebody prior has messed with the carb settings and the workshop manual that I have does not have basic carb settings or method of setting carb. It just says 'carb set in factory, do not adjust'   Can anybody help with the settings, particularly the 'H' setting?  It seems to be a bit touchy to set and I don't want to lean it out. I've set it very rich at the moment but a basic setting would be good.

Thanks in advance

I agree, but not seen him on here for a month or two? I hope he's ok?

He said he had retired so he may not look in as much now.

Have you googled partner cut of saw? They were up until a point husqvarna but yellow , from memory not much has changed on them

Good suggestion! I was surprised that it didn't give setting in the service manual, but still! As you say it's basically a Partner, even says so on the saw, Husqvarna Partner K750.

I'll check it out, thanks for the heads up! It's a shame if the site loses adw,  always a helpful and knowledgeable guy!

ADW is fine but like many, got fed up with the "political discussions" on the site that have taken over from what was a decent arborist site with decent content where guys like us can sort out the technical issues that we deal with on a daily basis but there you go.

On the K750....try 1-1.5 turns on each L&H screw, I usually tune the L by ear and the H using a tach but each man to his own.

The carbs are different between the Partner K750 & Husqvarna K750. Not suggesting the settings are different, but they may be.

 

The Partner K750 ceased production in 2006, when it then became the Husqvarna K750. the carbs for the Partner version are now obsolete, whereby the Husqvarna ones are still available from Husky. Both Zama models, but are different part numbers.
