Chainsaw Repair

Just had another class to refresh on chainsaw repair group FB on this chassis. So saving.

Dolmar Makita 5100 5105 510 5000. Havent messed with these in years. Need refresher. 
Some PHO dry weight of the 50cc.
510 was the open port with aluminum case.
5100 closed port with mag case.
5105 CAT muffler mag case.
5000?

510/5105 were available with 16, 18, 20" bars in both 325 and 3/8. Dam near the same price no matter how they were spec. So most shops ordered them with 20" 3/8 and most shops that had a clue avoided the 3/8 18" bar because of the oddball DL count

510, 5121= same saw. 5100, 5105, 5000= same saw. 5001, 5105H= same saw as 5105 but with heated handle

510/5121 were aluminum cased except the last of production run was mag cased... not a clue if that was the last 3 month or year or 2 years of production...I just know they did away with the aluminum case at the end.

510 was built in Germany then switched to China assembly then back to Germany
