2 stroke, kicks back on start?

4 posts in this topic

Is there a common issue that can cause a 2 stroke to kick back when attempting to start it?  I've got a Stihl chainsaw that runs great, but man, it's about beat me up starting it.  It kicked back last year and I broke a side off the T handle.  I fixed that last week and promptly got some bloody knuckles then broke the rope a few times.   I've got a technique of bringing it up on the compression stroke pulling it over ONE revolution (very short pull) that's helping, but if there's some adjustment somebody would point out I'd appreciate it.  And it's only the 034AV, not like it's a HUGE engine or anything.

Most new 2-strokes have a decompression valve to bleed comp on start, or a scallop above the exhaust port to help with that.

If you could have that done to yours, it would help.

^ Like a partially sheared key?   Man, it runs SO good that I'd hate to "fix" the timing if that's what it is. :shrug:  Maybe I need an Indy car starter...
