660 vs 650 vs 372 xp??

[tommer9]

Sold it ages ago. No regrets, have used one since and thought it an absolutely horrible heavy saw.

 

 

 

 

I had Ade's 660 and couldnt wait to get back to my 390 TCD. I seemed to be refuelling that 660 all day, and TBH it felt heavier to me. Need to get them side by side i reckon.

 

(BTW TCD, not had the timber delivered yet...anyday now:thumbup1:)

But is it the same carb tho?

 

Why wouldnt it be? Just 7cc difference. The Dolmar uses same carb on 6400 64cc, 7300 73cc, 7900 79cc for 15cc difference.

 

As soon as I get other laptop back I will get you carb numbers off the 650 660 IPL

 

Oh you do know even the carb venturis on the WJ carbs on the 066 and MS660 are not all the same too, right.

all i really wanted was a larger saw for large fells and milling... currently have 372 . just wondering what it wud be like against the 650 and 660

[Cut4fun]

A guy I know did the same thing when a 650 was offered so much cheaper then a 660. Same dang saw just smaller bore. Like I said wear it out and then put the 660 topend on it for the $$$ saved from initial buy.

I owned 10 or so 372 in 70.7cc 74.6cc 76cc and 3 066 MS660 91.7cc. Like any saw with more cc size they shine once in the BIG wood with bar buried.
