Partner 550 S55 P55 F55 65 650 P70 7000
« on: February 25, 2011, 03:13:46 pm »
I have 2 projects I have been working on, both 550. I am wanting to put a P70 or Partner 7000 topend on one of the 550's to make a 70cc 7000.

Anyone know the differences in the p70 and 7000 top ends?

what i have been reading, there was a good power increase with the 7000 plus. but the p70 runs good to. very good in its time. i wonder how close the p55 and the 550 are? i have also read that a k650 cut off saw cylinder will bolt on a p55 crankcase. making that a 71cc saw & 4.8hp. i think that may be an option also.   ;)

At least the bruchure I have (in Swedish) say there was a good power increase (to 4.8hp) with the 7000 plus, over the original 7000. Sadly, I don't know any details, as to what caused the difference.

It would be nice if people used the same user name on all sites, so I could recognize them!   ;)

Anyway, I got some "invitations" to this site, and it looks really promising! Less BS, and more focus on saw topics than the other sites I am on!  ;D

I just closed up one of the 550 to get it off the bench.  I forgot to get a carb kit and it is going to need one.

Anyone off hand know what carb was on the Partner 550? Just being lazy and not wanting to run out to barn.

Thanks.

Pulled the carb apart today. Dont seem like the diaphragm is to stiff.

 But I think the carb governor is messing with me. Going to take a bb and block it off and see what happens before carb kit shows up.
