Pioneer chainsaws

[Steve NW WI]

Looking back over your original question about the miss it could be just a bad sparkplug or a short in the wiring. The kill switch wire could be grounding, the sparkplug wire could be chafed through and grounding. The coil gap may be too large/open too far and then there is the most feared probability of the coil unit going bad.

I will get a flywheel puller and check the key out tomorrow, if I don't get any other cures.

I put a new plug in, but who's to say it's not bad. I have another I can switch out and test it. Visually, plug wire and kill wire look good. Coil? Maybe, but it has good solid blue spark with the plug out.

I did take the coil off and clean the magnets up, and regapped it with a piece of chain box, probably .010-.015 somewhere in there.

No one suspects that the reed not fully closing could be the cause of this? I'll try to get a pic after work tonight, but there's probably a .010 gap right now.

Well you are tracking down and eliminating a lot of the possibilities, if it is the reed block then that would be a new one to me, I have not seen them cause an inter mitten miss.

Well it pi$$ed down rain all day here so I got out the RA and put in a carb kit, man were the old gaskets and diaphragms stiff and hard but the carb was mostly clean. New fuel line,tank pickup and line between the fuel bowl and carb. Cleaned up the glass fuel bowl ,new gasket and round felt filter in there, new gasket between the base and tank. The recoil needed work so stripped and cleaned, replaced the friction washers and a new set of friction shoes, could use a new pull cord but will do for now. Pulled the rebuilt recoil and got a good grab on the starter cup, checked for spark and you could weld with that spark, bright blue and strong. A couple of squirts of mix in both the plughole and carb throat, replaced the plug and connected the wire, two pulls and it was running but it took four cycles of spraying fuel in the carb throat and pulling over,just one pull each time started the saw but it was slow to pull up fuel. It finally did and just as I suspected it ran way too fast at idle, could not dial it out with the carb setting, therefore I suspected an air leak.
Blocked off the openings and sure enough, failed the vac test, applied air and it is leaking behind the flywheel, likely a bad flywheel side seal. That will have to wait for another day but it has great comp and will make a strong runner.

After supper this evening I went out to the shop and put the RA on the bench, pulled it apart and installed new bearings and seals, put it all back together and it is now a very nice runner. Will make up a new chain for it tomorrow and if it stops raining get some cutting time in and a couple of picts.

It sure is good to hear about another piece of history being brought back to life instead of going to the scrap pile. Make some chips Jerry!

I mounted a 30" 3/8' sprocket tip on my P50. Now I'm on the look out for some big wood.

You know,.. Randy,..I really like fixing up these old saws and this one was heading to the scrap pile when Dan came across it. The RA is just too special to me to see one of them scrapped even if they need bearings and seals and all the fuel components gone through or replaced. The RA was the last of its kind, they were sand mould cast where the moulds were made by hand and once the metal was poured the moulds were broken to get the parts out. Imagine the work involved to do that, all the risers had to be cut off and the seams hand ground. Then the tanks being two or more pieces needed to be welded together and all the mating surfaces had to be machined for close tolerance fit. To make one that way today would cost thousands even if they were done assembly line. The art of sandcasting will soon be lost and fade into history but some of the products like the RA and its sisters will last for a long time. I have many more of the diecast Pioneers than the sandcast ones but I really respect the work that went into the early IEL`s, from the model B on up to the RA.

Hey, Jerry don't know if this belongs here or not, there in an interesting chainsaw for sale locally here, it an Partner R12? Is it worth while? I don't really have any room at the moment for it but it looks cool.

They are an interesting collector saw, not one I would want to run nowadays. Parts are a little hard to find but of course can still be found by those who are determined. Depends on what is being asked for it and if there are any members out there looking for one. I can buy a NIB Partner 5000 here right now but there is little interest in the Partner saws locally.

Hey Jerry thanks! He's asking $175 for it.

Here is some picts of the center emblem of the RA, thought I would post them here if anyone wants to copy it.

Great thanks Jerry.

I got an email last week from a guy trying to sell me an RA. Said he was going to decide on a price and get back to me.

It was a crappy pic but it looked all there and like it had been in a barn for thirty years.
I'd like to have one , they seem like cool old saws.

Not much of a limber I'm guessing...

They are heavy and slow by todays standards but back when they were all we had they were considered better than the misery whip or bow saw/Swede saw. I learned to do it all with them but dad prefered to limb with his double bitter and he was faster with it. I would fall and he would limb with his axe, then I would return and CTL whatever we were cutting at the time.

Got the RA all done up this afternoon, made up a new Stihl chisel chain, 64 DL of .404 and changed the clutch drum out just for the new chain, the old one had very little wear but now both chain and drive are new. Took it out but it was raining again today, heavy overcast and dreary/dark. Did not take picts today but will as soon as the sun comes back. It took very little to dial it in and it pulls very steady with that deep growl from the 103 cc that I am so used to hearing. Made some nice chips cutting hard rock maple that was only 18" dia. and cut dry for two years.

Sounds good Jerry, I sure wish you'd post up some vids of your saws!!

 

[pioneerguy600]

I am seriously thinking on getting some help to get me through the first video from taking it to posting it on you tube. I think my Canon camera can record the video with sound so perhaps in the near future.

I'm glad you got that one up and running .
I just finished clearing a lot and put my saws away when the rain slowed down today , I'll let the original owner know the saw is up and making chips , he'll be happy to know .

Its really easy Jerry. I could probably talk you through it. Do you have any computer savvy kids Jerry? LOL

I usually wait for my oldest daughter to come home for the holidays, she has a Masters in computer science and my youngest daughter has a few years of university using computers instead of books, they both can write the software and talk the latest technology in computer design. To get them to help ole dad with his limited knowledge of computer useage is like taking their charge cards away and stopping them from going out shopping. LOL
I get to repair their cars and stuff but no time to help ole dad. I am a hands on guy that learns from trial and error, if I put my mind to getting this done then it would happen, jusy have to get determined.
