That's pretty much what I was saying. At speed I felt the primer bulb and it seemed to me that when the motor bogged, the bulb went a bit soft. Then it filled and hardened again. The only doubt I had was that it didn't seem to make a difference whether I squeezed the bulb or not. The motor would still quickly drop RPMs, then pick right up again.
