Excellent and useful video.. I've just finished rebuilding the same machine.. I had to split the cases and replace the crank bearings too.. A lot of work, all running great now.. :))
Hi Simon, thank you so much for sharing your experience. I hope not to have to do that as this consaw is very frustrating to work on. But kinda learning too because it's the one and only I've had to work on and fortunately it doesn't belong from a customer. I've bought it cheap hoping for an easy repair but ended up in a real nightmare.
@@Dany_FIX_DIY Hi again, thanks for both of your replies.. I've learned that small engine repair can be both a nightmare and very rewarding too.. I have about five customers only, they understand that sometimes repairs can take extra time to complete. Here in the UK parts are very easy to get, quickly delivered also.. Thanks again, Simon..
@@simonwiggle1791 yes they are but everything is like that. I'm in the process of making a new video I should have uploaded it a week ago but unfortunately planets didn't aligned and it would probably take another week. I try to keep my videos very genuine, so the disassembling, repairing, restoring processes are not staged. Video editing makes them look very short but sometimes in reality I've spent even an entire day to just loosen a bolt 😅
@@paulfitzsimons883 thanks for the advice, I've checked it but I've discovered that the problem is caused by the intake plate which is not compatible with the cylinder I've installed. I need an earlier model intake, I've already bought it and it's on the way. Hopefully in few weeks I'll be able to upload a new video about this consaw
@@vadimslyusarchuk3212 hi, no unfortunately I'm located in Italy. Sorry I'm probably misspelling that now. Where did you notice the problem? It's always good to learn more about those things.

Hi, thanks for sharing. Did you refit the shaft and bearings for the blade head ? I'm just in the process of doing the same project going through a k770
Hi, thanks for commenting, it's very important for me. I'd like to receive more comments from the viewers to interact and help each others with our projects and build a little community. Anyways yes I did refit the shaft and the bearings, I did off camera to not loose parts because my actual workshop is few square metres and I have to keep the bench always ready for new projects. I've ordered a new carburettor for this Husqvarna cause it's the cause of the malfunction which made me gave up. But because I bought parts for it I cannot leave it incomplete. And maybe next video we will see it running . What's going on with yours? I've had little bit of struggle with the installation of the intake assembly because of the lack of space , especially for fitting the return line from the carb to the primer bulb , despite I have thin fingers it has been a challenge .
Hi, I have problem with my spindle when mounting a cutting blade. When I tighten the blade onto the saw it doesn't rotate easily. I think it might be the bearings or maybe something else. The motor runs nicely no problems at that end. It's just the cutting head that needs some attention. Taking the saw apart was a good opportunity to give it a good clean if nothing else , it needed it !
@@nicholastighe8450 I think you might be surprised. The thing works just like that. I didn't know either, but on the cutting head beneath the pulley there's a brake assembly, which is probably what you are referring for not turning easily . It's mounted on the pulley with 4 machine screws and has 4 little spring loaded pads, those run onto a stamped steel bushing fastened to the alluminum cutting head . When the rpms reach enough speed , centrifugal force pull the pads away from the bushings , releasing the brake . You still might have a bad bearing but you can just remove the pulley and check if there's any excessive run-out or noise in the bearings.
Yeah I thought it might be the brake but checked that and it seems fine. I am going to try rebuilding the cutting head and give it a try with maybe some new bearings

check that the bottom of the carb is seated properly in the lip on the cylinder,that could be the cause of your fuel problem,🤔
