Porting a Echo 620
That...filter setup looks familiar!First fire! Sounds healthy!
Heck ya! Nick does a great job... I suggest them on all my 620 builds!That...filter setup looks familiar!
I go fairly flat not totally but blent in nicly.. the ones you have to be careful with are 501s you will go through on those.Do you make the exhaust port roof flat out from 98 degrees? I've been afraid I'll break through to between the fins, so I curve up to 98 over the thickness of the cylinder. I too find 98 a good number on these.
Is the stock jet on these bypass drilled through into the metering chamber?Well looky looky.. I found a adjustable jet... looks like we might get a cutting video!
Yes the nozzle is one of the ones with the bypass. It limits the saw to around 12500 here and lower in high altitude.Is the stock jet on these bypass drilled through into the metering chamber?
