Nik's Poulan Thread

[EngineNoO9]

I had a friend interested in possibly purchasing my 3400. It doesnt get the use it should around here and I need to thin the herd a bit and concentrate on 1 or 2 brands anyway.
I had it out about a month ago and ran a full tank through it bucking firewood, so I pulled it down to clean the dust off. I fueled it and the darn thing would not start. Just my luck, no spark. I see coils are all over the place on Ebay but I thought I would check here to see if anyone had anything. I dont want to spend a bunch of money since I told hi. I'd sell it for $150 and I probably have that much in it already lol.

I'd check the wiring from the kill switch first before getting a new coil. Seems odd for it to just randomly die. When I reassembled mine once I didn't tighten the wire enough and the flywheel tore up the wire. In that case though the kill switch wouldn't work as it was always grounded. If the wire is broken near where it connects to the coil it may prevent it from starting at all... Just a thought. Multimeter to check continuity would be the quick check.

Those wires do wear through over time. Poulan used a piece of plastic tubing to cover the kill switch wire behind the flywheel that often falls apart and can eventually cause an insulation rub through at the hold down tabs.

The plug wire at the coil can also come loose and lose contact.

I always cut the little part on the flywheel, it's what seems to rub the kill wire. It's the bottom left in picture

That doesn't seem to affect the balance?

Those things that make you say fart nuggets to yourself. Had it all together but not really all. When I was tensioning rope I noticed it wasnt smooth. Then noticed the shield laying on other side of bench. So apart it came in a haste. Wrong move the pulley caught the spring end just enough and boing. Back together after I walked away for a bit. SMH

When I did that on a cheaper poulan saw I just got another cover vs messing with that retarded spring... lol

 

[Todd Loosli]

The balance of the flywheel is so small that you can't feel it, probably have more imbalance in it if it's plugged up with grime and stuff. It's so close to the center of the flywheel anyway. If you haven't looked at the flywheel they aren't balanced at all anyway.

Snip the end off at the kill switch, install some shrink tubing on the wire, heat it up to form around the wire and while it's still hot, lay it in place where it goes. Install a new terminal, just a little insurance for the wire.

I had a coil on a 3400 crap out a few years ago. I swapped on a Phelon from a Micro (or 2300) IIRC and used the original high tension lead from the 3400. I ground the core legs slightly to better meet the radius of the larger flywheel. Works like a charm. The Phelon coils were plentiful across the series of saws if you've got a junker kicking around. Maybe had to elongate the mounting holes...been awhile.

Need someone (Todd) to give me some kind of size reference for these gaskets for the Poulan 4200-5200 saws. The way they were scanned doesn't give me proper size. A simple length or spacing between holes for screws will be enough for me to make sure it's to proper scale.

 

[fossil]

These ones work for me. Just make sure you set the size field at 100% when you print.

If that doesn't work and you have the saw apart measure the carb adapter holes.

 

[EngineNoO9]

That's the one I have. I'll play with it some. It's a pain because I can't go straight from PDF to the drawing program. I have to either printscreen and save as jpeg, or print, re-scan as jpeg. After that I can then import into the drawing program and would like to make sure the scale is correct. I don't have a big saw so I'm relying on others for good info on those. The 3400-4000 I'm set on.

 

[Todd Loosli]

Ok bottom left gasket hole spacing is 1.78 and the opening is 1.2 x 1.490. Bottom right hole c to c 1.218 and opening .845 x .835 . Top gasket hole spacing of top holes 4.750 . Hope this helped

 

[Todd Loosli]

Center gasket is. 016 inches and this is critical for bearing play

 

[Todd Loosli]

Center gasket line up holes 6.182 for the 2 small pin holes

 

[EngineNoO9]

This correct for these two?

 

[EngineNoO9]

Then center gasket

 

[Todd Loosli]

No, hole spacing is center to center straight line

 

[EngineNoO9]

Quickie sketch in paint to make sure I have it right.

 

[EngineNoO9]

No, hole spacing is center to center straight line

.ok hang on.
