Do you have a video on corded electric chainsaws?

[@MowerMike]

Nope, I can’t think of a reason to have one. Not much maintenance on an electric saw. Do you have any ideas for a video?

[@barrykunkel1953]

Just curious why there are no gaskets used. Mine didn’t have any when I pulled it off. Would it do me justice to use the ones with the kit anyway? Ty

[@MowerMike]

I was wondering that myself, I have no idea why there are no gaskets

[@AlabamaFootball2010]

What did you set the gap on the coil?

[@MowerMike]

Excellent question, I totally forgot to gap the coil but it still ran. I usually just use a business card to gap them on mowers.

Not worth installing the 620 coil. Get a gearhead performance offset flywheel key. Same boost in performance at a third of the cost. 620 carb is the only thing really worth paying for.

Dang that is cool and he 3D prints those parts. Wish I knew this earlier, thanks for the input

NAMES JAIME AMERO CANADA . I GOT A NEW 590 . THERE MADE IN JAPAN .

[@stevenbenavente1229]

You can run a 27,28,& 36" bar on 590 but I would change out drum sprocket to a rim sprocket.

[@stevenbenavente1229]

You really need to order a red beard air filter kit.

[@williamtoney2599]

No….the 620 has a bigger carb.

[@MowerMike]

Little advice for ya. Try watching the 2008 film “Yes Man”. Is a great one

[@williamtoney2599]

I don’t watch movies. So your research, the 620 has a little bigger carb. I have both….
