Nik's Poulan Thread

Glad to hear you get them straightened out. Yes on loosening to oil cap or you will have a puddle til pressure bleeds off. I learnt my lesson the hard way, I sat my in the case, walked back over later to close the top and oil was all in the case.

Well got back to fixing my 2300 and 3800. The 3800 was leaking air at the pump cover. Had another cover and gasket that I installed and it now doesn’t leak and hold pressure. I also put a new check valve in the 2300, replaced oil line and it now oils. It does leak oil after shut off so I presume loosening oil cap will reduce the pressure. While in Vermont I also got my 3700 going with a carb rebuild and new recoil rope. Now all I have left is a 3400 and 4000 to get going.

Got to love the sound of a good tuned 3700

Sounds like everyone is getting some of the projects finished and have a few new ones to start. I'm doing the same. I'm a little jealous of your 375, can only imagine how it sounds, nice very nice and the smell of the fuel and the chips a flying

Question, when you get a saw with a broken flywheel fin do you take the opposite one off or just forget it

What saw? Try and locate another

Not even getting close to my projects. Just been doing others saws for $$$.
Sold 4 yesterday and 3 more on hold still for income tax returns.

Some day when it slows down I will get to a few of mine waiting in line.

2 60cc waiting on my to do list. 365 3.7

Thought I would show off the twin poulan. Maybe next time twin 60cc on both.

Really just to show differences of them for newer folks.

It's just a 3400 but not sure if I want to spend the money for another one

I would just run it, maybe someone has a spare and will chime in

Is that a twingle ,twin but a single, I could machine that case for some bolt holes if you're interested ,lol. I would like to take 2 weed whacker cylinders and make a twin cylinder engine

Bet that 3700 had the power with that much compression.

Steve

I have a 3700 here that I dropped the cylinder on and ported the cylinder advanced the timing and muffler modded. I tached it at 13,000 no load with bar and chain.

It cuts very well. It will run circles around my Stihl 036 or my Husky 455 rancher.

Guys that were a lot smarter than me say the single cylinder engine cannot be balanced well enough to notice the difference of one fin off the flywheel.

That's what I wanted to hear, thanks

Make you an opposed twin, be real smooth.

That would look awesome, slight v twin poulan, image the torque it would have, but I believe to keep it compact it would have to run reed valves with side exhaust.

Started working on the 3400. When cranking it I immediately noticed how easy it was to pull. Wouldn’t start. Did a compression test and it topped out at 118. Pulled cylinder , removed rings and checked ring end gap. Checked out at .077. Shouldn’t it be closer to .005 per inch of cylinder diameter or 1.8”x .005= .009?

 

[s sidewall]

Wow, big gap, rings look worn real bad?

Steve

 

[Todd Loosli]

Is that the gap plus the pin, just checked a piston with rings I have and it's just the pin gap. The pin is .062 on a new one

No. It’s just the ring gap not accounting for the pin.

No, surprisingly they don’t look too bad. Did order two sets from the “Greek”, .
