If I'm not mistaken the R440 is an earlier version of a P-100 .

Yes as far as I know it is. I think they changed the cylinder as to the T port design. It really all turned into the mculloch pro mac 100 I believe. My R440 was a real sorry case. It had sat out in the rain and one case half was real rotted....I just slowly got parts together. The real motivation was a NOS top end I got for it. It's a cool saw to run. The con rod does have some corrosion rot on the beam but I just don lean on it too hard!

Since a 440 has been mentioned I would suspect a Husky 272 coil could be used as a replacement just like it does on a p-100 .If it had a two piece
ignitron or whatever they called it finding one would be like hunting for a hen's tooth .If you did find one they often fetch about what the saw might be worth .An AM coil from Seek-Pro or Proline is only about 20 bucks,nice hot blue spark .

I' m not really sure if the Mac version was before the P-100 super or not .The super had the additional flywheel side brace to give it more strength which was the weak link prior to the brace .My Mac version does not have the side brace . I've only seen about 4 or 5 P-100s in my life other than the two I own. That said those old duffers have got some power .

P-100 from the early 80's & R-440 it's probably 1975

Has anyone tried to secure the hole under the clutch bearing in toasters? To reduce draft in the crankcase

 

[Al Smith]

That oiling system with the hole in the crank shaft has been a bone of contension .However as I understand it Husqvarna used something simialar on the 3120 model and it's been proven to be succesfull .
Where I live is not a high impact logging area .Partner as a brand was never a high seller but the concrete saws were .What little experince I have is based on the four Partner saws I own,two 99 cc and two 49 cc models .Very advanced for the time period and robustly made .

After 50 years, sealants may leak a bit in addition, there is a hole in the crankshaft and the saw runs poorly or does not rev at all

I never really saw the hole as an issue other than making it a pain to check that the seals ect are good. A constant air leak can be tuned out and not affect the saws running. It’s those sudden ones that get you. This is the reason I like mtronic and autotune because it can and has saved many saws

Nigdy nie uważałem dziury za problem, poza tym, że utrudnia sprawdzanie, czy uszczelki itp. są dobre. Stały wyciek powietrza można wyeliminować i nie wpłynie to na działanie pił. To te nagłe przypadki dopadają. Dlatego lubię mtronic i autotune, ponieważ mogą uratować i uratowały wiele pił

I will check it and let you know
