rebuild

Just had the local shop put new carburetor on it. Now it wont idle. Not a lot of power. Air leak, I think. Screw hole for oiler assembly screw is stripped. Older model, occasionally used hard, home wood lot. So maybe ring, bearings? I don't have tools or time to rebuild but I love the saw. Is it...

I have a husky k770 model, rebuilt the carb, gaskets were like potato chips. When starting, it will only start with the choke, pop off the choke and it will rev to full speed and takes a while for it to slow down when releasing the trigger. it also acts like it wants to be a "runaway" engine...

Greetings all! First time poster, but I have been creeping this forum as a technical resource for a few months. I am new to chainsaws and small engines in general. I wanted to share this rebuild project and sneak in a few questions :) My wifes sisters fiancé gave us a saw. It was in rough...

Hi everyone, I picked up a decent looking MS391 (PHO) on CL for $40, about 5 years old. The seller told me he accidentally straight gassed it. Thought he had put the oil in the 1 gallon can, then filled at the station, and the rest is history. He had bought it to mill with and it didn't seem...

So during COVID found a guy in a farm town selling a MS440 for $200, it was run hard and put away wet, but it ran, so I bought it. Then I got the great idea to "fix" what wasn't broken. Here is my advice to anyone who runs into any similar issues that I had along with a MASSIVE thank you to the...

At work I've inherited a saw that needed rebuilt onto a new crankcase. I didn't get the full history of the saw, I know it had issues with screws vibrating out of place so much so that a new crankcase was ordered as a potential fix. Here's my issue. I dismantled all the parts off the old...

so i bought a used 281xp to do some milling. after cutting a few slabs it wasnt runing right seemed ajusted so i started ripping it apart to see what was up. i fount the oil pump ajustment was sheared off unrelated to my issues with it running but am replacing the pump. i took the top end apart...

So today I was milling up some spalted maple with my 070 and 36” bar and I noticed it lost most of its power on the last cut. Feels like the piston and rings are going... I’ve got a 070 that may be a franken saw with Chinese parts sprinkled in but it’s been running like a champ up until today...

Old chainsaw restoration or rebuilds have always fascinated me. I decided to buy this 50-year-old vintage Pioneer 2073 saw and see if I could refurbish it an...

Hi, I have a Husqvarna 235 X-Torq that bogged down completely when under load, tried to do a carb rebuild (most probably badly), and now it wont even try to start. Also seems to really be an issue with the priming system as when I prime it, pressure builds up in the fuel pipes and in the fuel...

Hi Just got a good deal on an 066. Everything is oem except a metor piston and rings. The saw is an absolute beast and has no issues as far as I can tell but there are some cracks and small pieces that broke off on the bottom of the bar side of the crankcase. If this damage causes any trouble in...

Pardon me if i ramble a bit. I'm a city guy just moved into an off the grid cabin tucked away in the app. mtns. Picked up my first chainsaw this year from a friend. A ms170. Pulled the carburator and replaced it and off I went. Well, my next door neighbor (well next valley over) is a little...

Anyone in the know want to comment please? I have it torn down to this point (see photos) ultimately I need to get to the fuel reservoir to inspect and possibly repair/replace gasket as it is leaking just sitting on a table. This is the primary reason for teardown. Also going to rebuild carb...

Looking for what you would do you your 372 x torq. I'm going to throw a new jug and piston in mine and rebuild carb along with a muffler mod. Is their anything else I should do while she is apart that doesn't take anything too fancy or complicated to do?

I have an MS650 magnum with a scorched piston (and possibly the cylinder) that I’m working towards repairing. Looking for OEM parts to make it right.

This is my first post on the forum so please bare with me while I try to figure this all out. So I am in the process of rebuilding a woodchuck 12 inch chipper. It is a hyroller 1200 model with a 4b cummins. I am going through it totally from the hitch to the feed tray. What would a fair sale...

I recently decided to dive into resurrecting a saw. I got an ms441, paid way too much for it but hey live and learn. I’m wondering if there is a good building thread someone can direct me to. I’ve searched on here with little success on a good overview of the process. There are a ton of good...

Ok, it started at my $80 saw thread and now it's time to go back together. I ordered parts and cleaned it up a little bit. The case needs a little more "toothbrush" work, but hey, I think its alright. As far as parts, it's all new and oem. Piston kit, carb kit, fuel solenoid, handle...

My grandpa had a Poulan Pro 205 that sat in his garage for years unused due to a broken starter pulley that he never replaced. He gave it to me and I replaced the pulley and had it running. Decided to take it all apart and give it a good cleaning. I opted to use Fuel resistant permatex in place...
