Pioneer P26

[poncho62]

Hi all...I am new here. Looks like an informative forum.

Anyways, when my father in law passed away, we ended up with his Pioneer ^26 chainsaw. It hadn'r been run in a while and the fuel lines were pretty rotten. I replaced these, but am a bit confused. Most 2 strokes that I have worked on has a return line to the gas tank. This does not. Just one line going to the carb. There is another line that comes from the tank with a 1 way filter on it I think. The other end of the hose seems to go into a cavity by the tank.

I was looking ar another Pioneer thread and save the picture as it seems the same as mine..

Anyways, the only way I can get it to start is to spray some gas into the carb and pull like heck until it goes.....It seems to have very little power and seems to be running out of gas. I imagine a new plug wouldnt hurt....but was wondering if there was some other advise I could get on this.

Thanks....Harry

New fuel lines, check
new fuel, check

go ahead and change the spark plug, it's cheap enough that it's nonsensical NOT to eliminate it right off.

Does the pull rope give a nice pulsing resistance when pulled slowly (suggesting adewuate compression)? Poor compression makes a saw a bear to start and impossible to get to idle.

Go ahead and pull the muffler and look at the cylinder - is it scored, or not?

Seems to have good compression....I feel the pulsing anyways. Will pull the muffler and have a look anyways. ....and buy a plug. I know I should have already. Maybe the carb is gummed up from sitting too....will check that out.

thanks

OH! and welcome to AS!

Let us know how it works out - perhaps someone will do a search and learn from your experince one day.

P26

Hi welcome to AR. I have redone many of these saws, there is a fuel line and a tank vent line this line just fits into a hole near the carb and basiclly just sits there venting. As for not running properly , change the fuel filter and it will likely require a carb kit, which are still available, look at the carb to see if its a Tillotson or walbro. Before investing to much cash in this i would check piston and cylinder through the muffler exhaust port with a good light, if scored, its unlikely worth the effort. These saws are very good and have lasted for over 30+ yrs, i personally have a P28 and a P26 parts saw and most parts are interchangable among the lower numbered P models.

Thanks .....will ckeck it out. It is a Walbro, I believe. Is the filter available too, or do you just blow it out?

I am more of a car guy, and am just getting into the small engines.

If the flocking on the filter is ok go ahead and just blow it out, that's fine.

Off the top of my head I though a P26 had a Tilly HU carb. I wouldn't be suprised if there was a walbro in there though, which model that would be escapes me right now.

P26

Retoocs your correct these P26's came with a Tillotson HU, however, i have found some Walbro's as well, likely after production add-on & they will work as well either way. If the piston and cylinder are good and of course the coil has good spark these are very dependable saws i would take Magnesium any day over some of the plastic stuff today even though i personnally have switched loyalties to STIHL i will keep my P28 ( runner ) and a P26 for parts. I currently own a 029 super, 028 super and an 026, gotta love STIHL.
