  1. I have a 021 that after rebuilding the carb, seems to be still starving for fuel. Could this be a crack in the impulse line or intake boot?
    thanks for your help.

  2. yeah i know i saw that video but i meant like the crankcase?Like i saw some videos on youtube and they heated up the crankcase and then they put it together,unlike you you didn't have to heat up nothing cuz it's a different job i'm guessing?..Are they called the main bearings?

  3. I have a Stihl 036 PRO that a friend has asked me to do a top end replacement on.  The aftermarket cylinder does not have the stud on top that the cover secures to.  Do you usually use the one from the old top end or just purchase a new one?  I don't see how to remove the old one or install a new one.  Do you have any experience with these?

  4. The rubber intake boot is easily re-installed with a loop of nylon cord wrapped around the tube and threaded through the provided hole and tugged through the rear plate.  It will cinch closed as it pulls thru with ease. It also helps keep the pumper hose from detaching.

  5. Would it be a good idea to wrap one round of duct tape (or maybe electrical tape) to the tips of the needle nose so you lessen the chance of tearing a hose?

  6. As crazy as it might sound, you've inspired me to take some classes on small engine repair when I get the chance. I just think this would be such a handy skill to have as a man.
