Poulan 4000 thin ring specs bump

Thick .55mm = 0.0216535433 inch

49.2mm

I just ran a conversion for .55mm = 0.0216535433 inch


4000 bore 49.2mm

3700 47.7mm

3400  46mm




2017 info saved.  Tim's repost

Here are the actual displacement numbers in that series for the heck of it. The stock stroke was measured by a machinist that made a stroker crank for a 3400.

Poulan 3400, 4000 saw stroke is 1.319" (33.5mm) and displacement


Volume of a cylinder V=πr2h (volume = pi X (radius squared) X height (stroke)

3400 3.14159 X (1.81/2 )squared X 1.319 = 55.614 cc

3700 59.681 cc

3800 59.9999 cc

4000 63.562cc
