Look what happens when you don't check for a while--a Poulan thread and 473 pages! Have two 3700's, both working, done several repairs on both. Bought my first one (3400) in 1983 from a small logging shop in the Slocan valley ("Iz gud saw but Gud demn loggers von't buy--iz not orench!--dey all vant orench!"). Got stolen. Replaced it with an O34--got stolen (we have druggies here). Bought one 3700 on ebay, then got another for parts. Turned out both were so good I got them both running; used regularly, one with 18" bar and one with 20". Excellent saw, but not good for logging; handle castings have thin parts prone to breaking--even I tripped over one and broke it. Repaired again thanks to ebay.
Compliments Homelite 750 on big end, Makita 16" electric(!) on other. Bought a PP 2036 as an interim saw, constant trouble with the oiler; just not a serious saw.
