Need some port numbers

[old guy]

A few years ago I aquired an 044 stihl, even with a D handle this became unstartable for my 84 year old carcass.
So I bought a new stihl oem 046 cyl. & piston with a decomp button (made in Brazil).
I made a thinner base gasket which gave me a squish of .018, well, I can't start that either, so I went back to the original base gasket, squish is .032, now I can start it.
What are some good work saw No's to grind to, I will not be advancing the spark. Thanks

Do you know what your timing numbers are now as it sits? The 046/460 numbers vary a little bit so I was wondering which one you had to help you out with which way you should go

Thanks for the reply, I will have to take it down again & put the wheel on it, it sounds pretty nasty the way it is.

I put this thing into some hard 20'' red oak today, 24'' bar, I may run it as is for a while, it is a strong engine.
However it is pouring bar oil out the bottom with the screw turned all the way in & the idle needs adjusting.

Try the thinner gasket again and add a husky 395 blue button decomp to it. See if you can start it.

The Husky decomp is a direct bolt in and should pop at a higher pressure than the Stihl one. Most often, the Stihls pop for me at every start attempt. The Husky usually only pop if the engine fires. Push down everytime though.

I’m not sure why people hate decomps. I wish every saw had them. I’m old enough to no longer need to prove how strong I am. In addition, the decomps cause less stress on the starter mechanisms.

If someone can give me a sensible answer about how a decomp “leaks” in a running 2T motor I am all ears. Yes, a leaking decomp may cause a failed vac test, but it shouldn’t affect a running motor in any way.

Sounds like you made an 044/046 hybrid. Most 044 came with the “dummy” coil. If you can find an original 046 coil, it has start ignition retard built in. @jacob j. would know the PN. I forget it. It will help tremendously with starting. Most starting issues have to do with not pulling the engine over fast enough to get past the firing of the engine.

Another trick is to add a small “T” slot to the center top of the exhaust roof. I’ve tried on a few saws and it seemed to work.

Good hybrid numbers are 100/122/78 btw.

Thanks DRF256, I already have the 395 decomp in it & it only pops when it fires
That thin gasket is a bit too much for me tho. Thanks for the info about the coil.
I agree with you on decomps also.
