Hi all I’m a 61 year old farm kid, for now looking to see if anyone can be of assistance to help me resolve and early electronic ignition model McCulloch PM 850 failure No spark, died while finalizing yearly firewood processing, coil and electronic trigger are 2 separate components, combo...

Just picked up a practically brand new CS-2238 for $50 on marketplace. The guy said that it might’ve had fuel in it for about two years sitting around so when I got home I emptied it put some fresh in there the fuel didn’t even smell that bad, but still. I pulle and pulled and pulled, nothing...

Howdy folks, I got a project chainsaw for the right price, free! It is a Stihl 066 with the digital red light. I don't know if I have spark and the compression is shot. It looks like the saw was run without oil. I also noticed that the flywheel is missing a fin. Part Number 1122 400 1209. What...

Howdy folks, I just finished a cylinder rebuild on a Stihl 025. I got everything back together and fired it up and was tuning it in. It died, and I couldn't get it to fire off at all. I pulled the plug and turned it over and I had spark. I put the plug back in the cylinder, and it won't fire. I...

Hi everyone, I am new to the site but I am really in desperate need of help! I purchased a non running Wacker BTS1035 cut off saw on FB marketplace, I know not a chainsaw but pretty damn close. When I got it home I realized there was only a weak/ intermittent spark. Bought a new coil, cleaned up...

ok, here we go; I’ve searched thru and read a bunch about the ignition coil, mtronic carb reset, etc. here’s what I did... 1) New wiring harness from coil to carb servo connection- old one had two yellow & red wires cut. New Wires look good. 2) gapped flywheel with a business card...made sure...

Hello, just created my account. Decided to come down from lurking in the woods to the warm and tidy campfire that is arboristsite. I just recently purchased a nonrunning Homelite C-51 convertable drive for $10. The two main problems with it are it has no spark, and the 20" windsor bar was...

My 041 AV has served me well over the years and its been maintained it since new and is in better shape than most. I have not had to use it for five years and am getting ready to sell it. While it starts it did start, it ran rich, rough and stopped. Also found that the oil pump seals need...

I have read a bunch of threads regarding Stihl 064 and coils but I am still unsure what to do. I have a 064 with a bad ignition coil. The coil is Prufex CDIC (part 1122 400 1303). I have the single keyway flywheel (part 1122 400 1204). It seems like this is the worst flywheel to have if you...

hi all, Long shot, chasing an SEM ignition coil (IPL doesn’t appear to have a part number sorry) for a stihl 048 saw Currently have one, dies when it warms up and having had a few 056’s in the past with sem ignitions I’m guessing it’s the same problem I’m in Australia but happy to pay...

I'm hoping some of the regulars here can help me out on this. I have searched the forums, and found some good info, but not the exact thing I'm questioning. I purchased a MS250 from a flea market, which turned out to be a MS210C. The saw had been run without chain lubricant for quite some...

Hello everyone! I'm a real greenhorn when it comes to chainsaws and diagnosis/repair. But I recently just started collecting them because my wife's grandfather gave me a really good looking Super XL Auto and it got me super hyped. Well I purchased a Super XL-925 off of eBay, so when I get it...

Hi All, Just acquired a new chainsaw.... an old 051 (from what I have read anyway) as it has the compression release screw above the spark plug. I am interested in a couple of photos of the Nova/Atom fix and information about the diagnosis? Have read a few things on here but a lot of the...

Hi forum! So I figured I'd try to get my dad's old saw running again. No spark. A little googling turned up "blue Prestolite coil of death", and suggested baking the coil in an oven. That actually worked... for about a minute. A longer bake (24hrs @ 115C) and it worked for 10 minutes. Long...

Ok so I'm new to working on my own equipment and new to engines in general. But my 630 is having an issue with starting. Now here's where I gets complicated. It ran before the holidays and I was working on tuning it. So I had t sitting with a screwdriver in the high and low jets port and my...
