Chainsaw Repair

Do you have an ultrasound cleaner? I would highly recomend one of those for your carb. I have one of the jewlery very small models without heat. They would be absolutely sufficient if you don't need it often. It still works great. My procedure is dismantle the carb and place it into the us cleaner and add:
1. hot faucet water with simple green and run it max time
2. new! hot faucet water with simple green and run it max time
3. new! hot faucet water with simple green and run it max time
4. new! hot faucet water without anything!!! and run it max time, this is to remove any "soap" residues
5. blow dry carefully with the compressor, spray through all the holes with wd40, reassemble, run saw

!!!!What is important when exchanging the water => dumping the old water/dirt mix into the sink, is to dump it through a strainer/filter/sieve whatever! Because small parts like going down the drain too... Don't ask how I know!

Good luck!

zama carbs were known for trouble on the 5100 saws, don't know if the 5105 has same carb.  ?

Thanks for all the help guys. I have been thinking about getting an ultra sonic cleaner. I think this one is a jet problem as from what I have found from the original owner the saw had this issue from the beginning.  He took it to a dealer, the said they fixed it and after a couple hrs poof stuck ring. He got a new one from dolmar and bought this back. He had a lengthy thread on another site about his experience. I am going to pick up a cleaner but for this I think I will get another carb....This carb was used on 5100,510,& 5105 so should be something out there.

I guess I've been lucky not had any carb issues on any of my 6-5100's.

The solid sided piston should make more power if its like the 7900.
