makita 6421 tuning
« on: September 17, 2014, 02:55:21 pm »
ok I read the madsens carb tuning article and have it saved to favorites. I took the Makita and my tach out and tried my hand at tuning, the idle is a bit low at 2100-2300 but it will seemingly idle all day. just might be somewhere else in the shop when you come back(vibrates). the high I adjusted to 12900 and took the saw out and cut cookies for a good while and then let it set on the floor idling just see if it would. it did. nothing seized yet. bought this saw to learn on and I am ;D

12900 would normally be a good setting for the top end.

On the idle, you don't want the saw to quit and you don't want the chain spinning either. Anything else is OK.

Congratulations on your maiden voyage, very satisfying is it not! Now you will just be itching to buy another and play with that, it is addictive. ;D ;D ::)

yes it is addictive, have a poulan I need to reassemble. sometime in the future my 6421 is going to become a 7900. if we had the internet earlier I might not have been so worried about killing a saw.
