Husky 61 White Top need Jred Top Model#

[NCstihl]

I have looked through many old threads and did not find an answer.

I have a White Top Husky 61 Practical/Rancher. Serial number 1611 133615, assembled 8/23/78. I installed a Meteor 72cc top end with the later 61 or 266 air intake system and filter. I've done this before on older, orange top, 61s with no fitment problems, once cylinder studs we're fitted.

Problem with this one is the white top has zero clearance. I read the Jred 630 cover is a good upgrade including that filter system. What is the model number of the lower cover and upper cover? I'd like to upgrade to take full advantage of the power train without melting the hat.

The later 61 covers don't fit the white top and I don't know if the later 630 models changed or what will actually fit the saw.

If there is another solution other than spacers or going topless I'd be interested. Thank you

The white top ones have the lowest clearance. A grey top 61 or 66 will work with out hitting. A 266xp cover will fit also. The later orange top 61 the one screw hole is not in the right place.

I think any of the older jred with the two piece ignition would fit on the case. The filter elbow and other bits would need to be sourced too.

625, 630, 670 were in that family

Thanks guys. Useful information. I appreciate the fast replies.

If my memory serves me correct I believe Walt did a video with the old white top and I think he drilled a hole where the spark plug is

I managed the spark plug by getting a shirt Bosch and trimming the rubber top on the plug. I managed the air filter by trimming the spacer. But there is zero clearance around the new muffler, particularly at the seam and above, even with 2 rubber bumpers.

I considered letting it go topless but my 288s started.....rumbling.

The muffler can be reused from the old 61. It should be the three piece one that comes apart. It is easier to mod. And is shorter to clear the old top.

 

[NCstihl]

Thanks Kysawman. That's probably cheapest and easiest. But that's one ugly muff. On the other hand it may keep my 288s away from my blonde.

As said earlier you need an early gray top 61/66 cover....or a 266 cover early Jred cover fits the case but the air filter cover with the integral sparkplug cap will not fit on the 272 cyl. It's the angle of the sparkplug that is the problem....the Husky plug stands up much straighter than on the Jred cyl. This pic shows what I'm saying.....these are all OEM Marhle cyls... the cyl on the left is a 272XP...middle is Jonsered 630 and on the right a 268XP...

If you use that old muffler I would advise you take it apart and remove the screen baffle........this one broke up after many hours of use and the missing piece went through a newly rebuilt 266XP with about ten tanks through it.....it now has a new piston, main bearings and seals...just by chance the cyl was usable again but everything else was trashed. I would look on ebay for a good used early 61 muffler....just a way better muffler overall. The 272 muffler, though an excellent muffler, is designed to fit under the new style top (after the case change) which is higher.

I'm quite sure a 61 gray top cover made after 1991 week 7 also have the clearance, as those have the same shape as the orange ones that was used from some time in 1993 (late 1993 if memory serves). However, those will not fit on the case of the saw in question, as they are for the "single-coil" case (the screw hole issue that you mentioned).
My point really is that there are two versions of the gray covers out there - one for the "twin-coil" case and one for the "single-coil" case.

Ideally a saw with the 72cc top-end (and hopefully a corresponding 17.5 mm or larger carb) should have the taller/larger muffler of the 268/272 etc. as well - but as mentioned already in this thread this can again lead to top cover fitment issues.

Size does matter when it is about chainsaw (box type) mufflers, not just how "open" they are.

Btw, this hardly is a new topic on here, so I'm a bit surprised that a search didn't turn up most relevant info. A Google search often works better than the on-site search system though.....

Thanks Robin, missed the plug angle factor. I also always remove or replace the spark screen, depending on where the saw will be used.

I used Google for my search and got a lot of good data, some of it above, but not the 630 or 670 cover(s) model numbers that would fit, or the model numbers of other covers that would fit. And the various IPLs don't distinguish specs on height or screw location. Plus, with all the Frankensaws, part numbers on non original parts, even if OEM, do not necessarily match the year or model of the case. I'm still hoping for model numbers.

I do appreciate the responses and information. Every post gives me more info. The search for older, often discontinued parts, gets harder as existing parts are scooped up or destroyed.

Again, thanks guys.

In the case of the old 61 muffler, that I call the "fish gill" muffler due to the fact the exhaust exit consists of three slit in the body, the screen is actually very large and probably doesn't really restrict the flow that much....the problem is the two layers of baffle that the screen is sandwiched between.....they can fail through the many heat cycles...if the outside one fails it's no big deal but if the inner one fails it can become a real problem quick.

Niko is correct too, in that the gray tops went through the case change, so just finding a gray top doesn't mean a sure fit. However that said there are vastly more old style gray tops out there than late style.
Some guys have said that the late model 670 air filter covers will work on the early top covers and are tall enough to handle the plug angle change....I know the 630 cover won't but have not tried the 670 covers myself.

That's really helpful. No snark, no smart a$$. I appreciate your continued follow through. Good to know the 630 covers do not fit.

I learned something new today did not realize that they had made gray top single coil models. Thanks sawtroll. I will have to find one of those for my collection. The 61 series is my favorite saw!

Cool - but the most correct name for that model family is 162 family, as the 162SE was the first of the models (1975).

OK.......had a few minutes here at the shop and decided to look further into this top cover thing mostly in as much as it pertains to the Jonsered side of the family. The early top cover from a 630 or 670 will fit any early saw Husky or Jonsered in this family......however as I said earlier the 630 airfilter/sparkplug cover will fit any on the Jonsered cyl but not the 50 MM 268XP or 52 MM 272XP due to plug interference......however it will fit fine on a Jonsered with a 50 MM 266XP cyl. Which is interesting but the most interesting thing is that a 670 airfilter/sparkplug cover will fit any of the common combinations...670, 630, 266, 268, and 272. on either the early or late Jonsered top cover and or cases !!!!!!

Great, I have a lead on the lower 630 and 670 and the upper 670.

Thank you
