Tried calling. Left you a message.

I’ll call you tonight.

I’m just outside of Paris Ontario. Shoot me a PM if you’re interested and we can discuss.

Negative. My 066 parts are about all gone.

Sorry, they’re long gone.

Hello. I’m here now.

I agree with JMS. That saw is a copy 100%

Yup. I believe he did. Iirc he blended the lower lip with epoxy rather then grinding it out and blending it. Other then that his transfers and stock. I think that after the chamber and base were cut his numbers landed right where he wanted. No need to change them

Keep the space between the bridge and the back of the tunnel narrow. Don't open the uppers any more then you have to. Focus on the direction of the fresh charge more then flow volume. IMO opening the lowers helps to add some volume but by keeping the tunnels and upper transfer ports small...

No real secrets to building a good running hybrid. Intake at 79-80. Keep your exhaust and intake durations close to the same and 22*-24* of BD. Keep your transfer tunnels as tight as you can. Open your lower transfers up slightly. This is what I do anyway. Your mileage may vary

Did someone say 044 hybrid?

I just re read the whole thread. I get it now. Good one @Jon1212 now my head hurts

It's not just you. I noticed that as well. What's going on here?

Almost every saw will benefit from opening up the muffler. The ms290 and ms390 both respond very well to a muffler mod. Exact gains will vary depending on the muffler mod. I would think a 5%-10% gain can be had on a ms290 or ms390. Make sure you retune the carb( both the low and high sides)...

That looks great. Looks very strong. Are you gonna paint it or leave it raw aluminum?

I was really hoping to have a couple shirts. I hope the shirts still happen. I'd be in for a hoodies and a couple t-shirts

I'd do a couple quick check before deciding to just toss the saw in the trash. I would be checking the spark plug or replacing it just to be sure that spark wasn't the issue. Check the spark screen in the muffler. Make sure the screen is clean and not coated with a layer of carbon. If you...

For advancing your ignition timing all you have to do is file .020"-.030" from the key. (Make the top half of the key narrower. Leave the bottom half of the key as is) This will advance your timing approx 4*-6*. When you reinstall the key into the crank make sure that the side of the key...

Wow that's a lot of compression. I know there are a lot of guys running upwards of 250psi in some of there saws and they all say that there saws are holding up very well but personally I'd be a little worried about my crank with that sort of compression. WOT and have a sudden shock load on the...
