Sorry to intrude but not sure how to post to pioneer forum. I have 2 pioneer farm saws, a 1980 bought new and a 85? I picked up a few weeks ago.It was very clean on outside but hadn,t run for many years .After cleaning fuel system and carb found no spark.Unable to find a new prestolite coil so figured I was screwed. Looking at Leons chainsaw parts and repair blog it told about drying out the coil. Voila it runs again! Have read 209 pages of the pioneer thread so far and found it very interesting. I have the chainsaw disease also owning 2 stihls, 3 homelites, 1 jonsered numerous poulins plus the 2 farmsaws and a parts farmsaw. Looking at a p45 now. Allan
Congrats! The baking trick is a nice cheap fix. I’ve heard that some people have had short lived success with that but I’ve done it a couple times and have not had any problems.

Welcome fellow baker (fxer);
My Farmsaw has only once lost its spark, and I am probably to blame for that happening (stored on the ground under a tarp during a GTG).
It was a fair amount of time (I'm guessing over a year) that it did not run. So far (knock on wood) I've only needed to remove the moisture that one time (several years ago). I do normally store her in a garage and about 4 feet above the floor.
Good luck to you with both of your saws.
Wishes for good health and happiness to all ArboristSiters.
Lou

I’ve acquired a P41S a couple of months ago. I did the basic stuff to it. Overall cleaning.
Fuel lines, filter carb kit. Replaced the cracked reed block. New chain, bar, rim.

Ive run it a couple of times. Starts nice and idles great.

Seens to run really rich. Four stroked like crazy!

It’s had I believe the original Tillotson HS 147 on it.

Does this have a governor? Can they get stuck? Anytime I have to close the hi needle down to 3/4 to 1/3 I get a bit nervous. As a matter of fact I’ve never had to to run a hi jet like that.

Am I missing something? Possibly the inlet is set a bit high....

I thought that was the governor. It’s a ball in there or something right? How can you check them? Simply unscrew it and clean it ?

There's a spring and ball in the brass plug. When the vibrations get to a certain point which would indicate over speeding, the ball rattles enough to open the governor and dump fuel supplied by a hole in the metering chamber into the main jet.

I've never had one that failed but some guys block them off. They are inserted with something like red loctite so they are difficult to remove. It's best to remove the choke shaft (watch the ball and spring in there don't get away from you) so you can get a proper sized screwdriver on it. You can make a plug out of a piece of pop or beer can by punching out a piece using a paper hole punch, drop it in the hole and put the governor back in

The other way you can block it temporarily is to block the hole where the fuel for the governor comes from. It's under the metering cover beside the metering needle.
You could use a piece of the appropriate sized "O" ring

While your in the the metering side, do check the height of the metering needle lever and make sure the spring is seated properly. It would be best to do that first before you start messing with the governor.

I’ll take a look at the inlet lever. You would think it would flood out at idle if I set it too high, but something is wrong.

I don’t want to remove it. Seems like a good fail safe. I m pretty sure I have a number of Homelite saws with Tillotson carb with a governor and none act like this. Now that I think of it the Farmsaws that I have must run the same carburetor and they are all set at around s one full turn on the hi...

I am getting ready to go get a 650 about 100 miles away. The owner says it runs with gas sprayed in carb. Hasn,t been run for 10 years . All there but clutch cover has been welded. I,m excited. Will have pictures later if I can figure how to do it. I,m not very computer savvy Allan

A P45 is a fine saw.
