I found that aftermarket PCs are not made to the same specs as OEM. I recently rebuilt a TS420 concrete saw and used a AM PC. I measured the squish which is the distance of the piston to the upper limit of travel. This measurement when compared to the OEM measurement will give a heads up on...

Picked up a 2013 Husqvarna 440 Xtorq yesterday for $50, one owner. I know it isn't one of the great saws but it's a good start to learn. Starts cold, but owner said frustrating to start warm. Compression was 120 psi and leaks bar oil. Not sure what is the factory compression is but it...

Decided to pressure test today but had problems putting the intake boots back in to the carburetor plate. I just pulled the boots off the cylinder and was going to pull them into the plate and then push the boots on. I found a nice little crack in the bottom boot. I had ordered a bottom boot...

Getting closer to pressure testing to find out the high idle issue source. Made a test plate from 1/4 inch aluminum and a old carb inlet tube. I drilled a hole and heated the plate and inserted the tube and when cooled it was in really tight. I added a little epoxy just for good measure...

Tried to get the idle speed down today. Didn't matter if I removed the idle throttle screw or adjust the mixture screws, the idle was too high to get the clutch to disengage. Saw would rev up smooth and drop down quickly to a point where the blade would just about stop but then speed up again...

Played with the saw today for a short time. Compression test showed 125 psi which seems decent with new rings and cylinder. Saw started after I realized I had the choke in the open position, didn't pay attention to the markings on the cover. It was at a high idle but ran good and it had...

Once I get this AM carb and saw fired up I will try pulling out the plug and see if I can get the jet/check valve out and fixed. I figure I can solder up the plug to fix the hole I used to pull it. I don't think I can find a replacement jet/check valve.

I tried to soak the carb in mineral spirits and used my ultrasonic cleaner for 30 minutes but the main jet valve is still leaking when I pull a purge vacuum. I received the aftermarket carb today and pulled a purge vacuum and no leakage. Quality seems really good on the outside and I will...

More testing today yielded a good purge bulb and fuel hoses but still wouldn't pull enough vacuum to prime the carb. Not sure of what the item is called but the check valve that is in the venture but it leaks vacuum when I use the primer. I can't get access to the part because it is covered...

Finally got back to my winter project. Everything back together and finally filled tank with fresh mix. Tried to prime the carb but would pull any gas into the carb. I am a little confused on my findings. I connected the primer to the carb which I removed from the saw and was able to pull...

Does anyone have a Service Manual for a Husky 150BT blower?

I am in need for a service manual for a Husky 150BT if anyone has one out there.

Started on replacing the gaskets and needle valve but had some bad experience with the card rebuild kit. The gaskets seem ok but the needle valve was different length and the lever when installed didn't function properly. Had to put in the old stuff. Bad kit from HL Supply. Interesting thing...

Been distracted on this project because of multiple snow storms and a little kitchen remodeling, Half an hour in my small ultrasonic cleaner and it was clean enough to start to disassemble. I posted a question in the Carb Forum about the pressure it should take to pop open the needle valve...

Working on a TS420 Stihl cutoff saw and came across an issue in the carb. On a K970 Husky I did the same test and the pop off pressure was about 15 psi. On this Stihl carb I did the same and I pumped it up to 25 psi and it didn't pop the needle valve. The needle valve is not stuck since I can...
