Dolmar 6400 Muffler Mod.

How do you get the stuff out of the adjustment screw hole?

 

Pick or a little torch. It's epoxy.

 

Can I use a soldering iron to pick it out? Not a big fan of torches and carburetor.

 

Probably so. Some people used a butane lighter. Anything to get it warm enough to releast and come out.

 

Ok I'll give it a try.

 

I just did a 6400 muffler yesterday.
I've done easier muffler mods for sure.

 

What was the hardest part for you? To me it just seems like I had to take a lot apart to get the muffler out and now the epoxy on the adjustment screw.

 

Uncrimping it kinda sucks.

 

I just ground the crimp off and welded it back. It was not to bad that way. But I understand stand not everyone has access to a welder.

 

I wasn't sure about welding stainless steel so I opted to un-crimp it. The "pencil flame" tip on my propane torch wasn't able to get the crimp red hot very quickly so I got one of those tornado flame tips which impressed me how much better it worked. I worked about an inch at a time and eventually made it all the way around. It was slow going but relatively easy.

 

I warmed up a whole side at a time and used a scrench.

 

I was a professional welder for 16 years. Working now as a welding inspector. I like to make a weld every now an then to make sure I still have the touch. It is a handy trade to have some times.

 

Here's my 6400 with the newly remodeled muffler. Ported 7910 cylinder

 

That's a beast. That's what's in store for my 6421 as well. Only difference will be the HD air filter kit.

 

Thanks freind, I'm Lookingfor a HD setup.
I have a bunch of saws but this one is among my favorites.

 

After seeing that I may need to put the big bore kit on mine.
