great video brother

How did you get the end off

Man that truck won't make another few years from the rust I'm seeing

Huge help on my 2017 250x. Thanks!!!!

What happens, physically, that causes the valve to need to be ground down? I get that the clearance is off, but it fit before with the same length, so why does it now need to be shortened?

After I changed my filter, my quad won’t start. I need to flip the start switch on and off to prime the pump only for it to start and run for like 5 seconds

What model number of engines have the .008 .012 valve clearance?

So if you repace the springs and the caps would you have to grind the valves? It just don't make sense that the alve stems length could increase.

They should be ground nice and square on valve grinding machine not bench grinder , thats why they wont last long nut good video

Dolmar is NOT made by Husqvarna, they originally made by Dolmar themselves then Makita bought them out. Which makes them made by Makita. And Makita is NOT owned by Husqvarna. And you never use brake cleaner on a carb, you use carb and choke cleaner. If you don't get all the brake cleaner out of any holes or groves in the carb it can dry out the gaskets and diaphragms. And if you had that much saw dust in the carb you need to clean or replace the air filter (most likely replace). So please know your stuff before putting the wrong info out.

What size is that axle nut?

Once you grind these valve stems they won’t hold that clearance very long… maybe a season, depending on usage. Valve stems are obviously hardened by heat treat and you just ground it away right at the tip and point of impact. Also, the heat from grinding will usually compromise the remaining hardness of the rest of the valve. These flathead engines valve clearances were basically made unserviceable… you gotta buy new valves and springs. The valves stretch over time from hundreds of thousands of cycles and the springs lose tension.

Dang all you're links looks awful lol

Thanks for the video, I was able to use it to get my Dolmar going after it's sat dead for 3 years! I didn't realize I missed putting one of the gaskets in when I rebuilt the carburetor. I noticed after I watched your video. Thanks again for the detailed rebuild video!

Engine no start = BS, I want to see it run and check the compression.

When it comes to being made by Husquvarna, I think you have Dolmar Confused with Jonsered. Good repair video!

Some of those carburetors have the adjustment screws encased in epoxy so they can't be removed or adjusted.

Did this help with the heat?

Dolmar made by Husq. stopped watching right then.

man my dollmar 117 carborator has a dioframe probleme but no one has parts what do i do man i love this beast of a chainsaw

My friend maid one for me. But I want to put it back together. Like it was.

Valve lash is... .008 min to .012 max. Nothing under...nothing over.

Someone gave me a working saw just like this. Great little saw. Learning things with it. German saw right?

Put the breather cover on backwards.

what size for the axle nuts

Good video

Very helpful tutorial bud. Thank you very much. Pretty sure Dolmar is made by Makita, though.

What oil do you use? Do these have oil filters that need to be changed as well?

Didn't show you checking for top-dead-center compression leakage, insuring your made good contact with each valve-to-valve seat after doing a lap job. A poor lap job means leaks and loss of compression and a loss of horsepower while running.

At first you stated that the "Intake had .008 clearance, and the Exaust was at .012 clearance. Later in your video you set them in reverse to what you fist said the clearance was where Inatke you set at .012, and intake at .008. Which is it? I believe it's set at what you stated at the beginning Intake at .008 and exhaust at .012. You set your valve setting wrong in reverse. Intake is always open a wee bit longer than the exhaust valve, so the intake valvehas the greater setting (.012), by a few extra thousands of an inch than the exhaust setting..

If your going to do a small tune up at least change the air filter and the spark plug why put back a dirty air filter .

I have a similar snowblower and I'm pretty sure the head gasket is why its spitting gas out the front. Decided a little refresher was wise.

Thank you for taking the time to make a video, it helps a lot , so I have a ? .I have left a spring wire about 1/8" diameter left after build and its maybe 8 " across ?

Great video! Just bought an old beast for $20. Oil was super nasty. The guy said he puts carb cleaner to get it to fire up too

This solotion of a engine going over all bad solotion , not normaly to grind the end of the valves , to get the right valvecleranse.

Front tires

Where's the vale grinding

i think he is worrying with bottom end of the valves as long as they arent tuching on the bottom the valve will seat but he failed to grind them a comressin test will show if they are leaking

the way to tell if it is the valves or rings causing low compression take a compression reading the remove the spark plug add a spoon of oil in spark plug hole retake compression reading did it help if so its the ring are going bad if it didnt help its te valves need grinding simple???

Great video buddy

So it's double bearings on the left rear?

Did not find your follow up video of this brush cutter in action cutting down 4 foot tall thick thick thick grass with brush field ! Want to see it in action boss !

Dolmar is NOT made by Husqvarna....

Excellent work my friend Greetings from Costa Rica

Dolmar was the Original brand, and Mr. Lerp is credited for producing the very first chainsaw, albeit a two man behemoth. Andreas Stihl later took credit for the first one man saw. Makita bought out the Brand in 1991, and shut it down in 2022. BOO Makita! Better develop some ‘Real’ batteries, if you're expecting any performance outta those battery saws! Sheesh! And Boo to all the New deal whack jobs! Yeah! I believe you need to ditch those ‘Crapsman’ screwdrivers, and get a good Phillips screwdriver, and I think is is a T27 that is needed for the screws? It looked like your T25 was slipping some. Saw sounds rough. I think it has been run too many times, and ‘put up wet’ as they say? I applaud you on the tear down and the reassembly. Don’t forget the air filter! Peace

And now your valve seal is cut. Good one. People dont do this. Do it right

Where can I find a replacement snap ring

Bro can you tell what brand that bearing puller is? Thanks
