Chainsaw Repair

Hello all hoping I can get some input... I have had a couple of saws a craftsman and a poulan they were ok saws but have both worn out over the years I mostly cut dead standing trees and laying on ground trees for fire wood for the wood stove. I had bought a Stihl MS290 farm boss 20" bar saw and used it for a day it is ok I like the power it has and ease of starting but it just feels real heavy and large for my use.

Then I came across a package deal on 2 MS260 saws 1 of them 20" bar runs great the other 16" bar has a blown top end. I ran the 260 with the 20" bar for a couple hours and it feels much better to me lighter and less bulky than the 290 and with plenty of power hower it is a **** to pull the starter like it has unreal compression not sure if this is normal for the 260 or not. I see the pro model have decompression valves on them to make it easier to pull the starter so that might be an option? Not sure what to do with the blown 260 to keep for parts or put a new topend on it to sell to recoup some of my money. I will sell the 290 for sure. 

I see lots of top end kits on fleabay real cheap but usually you get what you pay for.... who make a decent kit for these 260's and is their much difference between the 44mm kit and the 44.7mm kit?

Looked around have not been able to find one and I have read they go up around $300 that is way more than I would want to put into the saw I don't think either saw is worth much more than that

I looked into the Meteor top end kit for the MS260 and have been told they were badly flawed and Meteor stopped shipping them... guess this explains why they are not around NWP seems to be getting decent reviews. I had an MS290 and did a carb muffler mod on it... do these same mods work on the MS260? My saw has the 2 adjustment carb on it but I have a parts saw that has the WTE 3 adjustment carb on it thinking of putting that carb on my user saw

I used the NWP top end kit and it works great from what I understand meteor is the best out there except the 260 kit for the 260 NWP is best from what I have found in my research I just polished the ports up a bit did not alter them then did a muffler carb mod and it woke the saw right up might do the squish on it as well that is supposed to give even more power

Well I got a race with my neighbor and his husky 50cc 346xp next spring his saw is stock with 18" bar I have a 16" bar on my 260 I know the huskies are supposed to be fast but want to see if I can beat his new husky with my 25 year old 49cc stihl the looser has to buy the steaks and beer for a cookout
