I'm no Mr Universe, but I'm no wimp either. I have just acquired an 80 cc chainsaw that seems to have too much compression. I cannot pull the starter cord fully out in one go. I first though that it might be seizing up, but it pulls no problem without the spark plug in. I didn't expect it to be as easy to start as my 254, but this is impossible! It's an older model without a decom valve. Anyone have any idea what the problem is? If I can't fix it, I'll have to hope Popeye is in the market for a saw.
