McCulloch3.4 Eager Beaver or Timber Bear - No Oil To Chain

[a. palmer jr.]

My Tillotson carb does have an idle speed control screw, but no idle or throttle stop. The idle speed control screw acts internally on a lever or something inside, I guess.

It can be seen at Tillotson here http://www.tillotson.ie/docs/HSPartsList.pdf

Or at Makita here. (98% sure these are the same carbs- one shows the throttle shaft, and one doesn't) http://www.ereplacementparts.com/makita ... _3090.html I think it might have been page C, not sure

I'm guessing it may be bypassing some of the fuel/air around the closed butterfly but never saw one of these before.

Little different topic, but still 2 cycle......

Anybody know the minimum acceptable compression on most chain saws. My dealer tells me it's 90 cold, but I have always heard minimum acceptable numbers higher than that, before you do rings etc.
