Husqvarna 262 and HDA 87

[trooney]

what year did they stop putting HDA 87 carbs on 262's? And if a saw has got a zero as its first number does it mean it was built in 1990? Thanks

Far as I've seen they used HDA 87 carb on KS and Gilardoni cylinder, I got KS&87 on an 93 I have, wouldnt surprise me if they used KS&87 later also even their IPL say something else.

Dont think they used HDA 87 carb on Mahle cylinders, about 95 they changed the TR numbers on those cylinders, at least on my 95-96 jugs.

Serial tag starting on 0 is a 1990 model.

If you want an HDA-87 on your 262, you can make it happen, there are lots of those carbs out there, you just have to put up a Want To Buy ad and say, "money is no object". That is what I did and I had a seller within a couple days. I didn't care what it cost me; I wanted the most TM could get me out of the saw.

Thats the info I was looking for. Thanks Tor. Wasn't quite sure but it doesn't have a compression release so I'm thinking it is a KS cylinder. Its for sale here and it would probably spark some interest if I went asking about stuff. I just didn't want to drive 4 hours for nothing.

If the information about the cylinder and carb matching are all true up above then all this hype about the hd87 may be all wrong. The gilardoni or ks is likely where the difference is.

I believe the KS is thought to be better cylinder out of the box but all is made equal by porting. On the other hand, its alot harder to make a hda120 deliver as good as a hda87. The difference is not huge and the hype is fueled more by the difficulty to obtain the 87 imo. With all that said i have a 87 on my saw and wouldnt change a thing. Its a mean 262.

Have you seen a gilardoni?

 

[trooney]

You might be right. I've already got 3 of them. Just want it for its resale value. The cylinder is a plus too. Everytime a seller knows hes got an 87 carb the price goes up!

the first type Mahle didnt have decomp valve, but you should be kinda safe if it's an 0 or 1 in the first letter in s/n. First when we head into 1992 you really dont know for certain what you get before you have the saw in your hand

to make it a bit more complicated, the first Mahles I saw had pretty much the same timings as KS had, and they had HDA 120 carb unlike KS & HdA 87.

48ZN15 & HDA 120 who I saw on my 95-98 saws had huge different in TR # compared to KS & first type Mahle, but, my 98 Mahle 48ZN15 has timings as KS used to have

Just saying there is no true answer of what you get when it comes to 262

My saw with the early non decomp Mahle and 120 seems snottier that the later decomp saw with a 120

If you are asking if i have seen the numbers, i dont own a degree wheel or porting tools so 'seeing' a Gilardoni, KS, and Mahle wont tell me much. Others have discussed this topic many times and ks numbers have been found more favorable than the other two. While I believe this to be true, I also believe the rarety of the KS fuels the desire and legend. Heck I would like to have a perfect KS now but it would still have to be ported to make a proper 262. Even without a hda87.

No, I mean visually off the saw in your hands. Their transfers are designed and shaped way different than mahle on some models so I was wondering if the 262 is the same way. I have a 262 but I think it's a mahle.

Very interesting. I have not visually compared them. I have only owned decomp and non decomp Mahle cylinders. Be interesting if somone can post some pics of the difference in port shape. Good info Jim.

Non decomp Mahle has huge lower tunnels compared to the decomp Mahle.

So what's the difference in the 120 and the 87? If they're the same size carb, then an exploded parts diagram should be able to pinpoint the differences. In which case, just order the 87 parts, install and you've got an 87.

I've seen differences in carbs coming down to just a different metering spring - something that costs less than a buck.

I believe @Tor R has a pic of the carbs side beside. Maybe he will repost it for you.

It's got a different bore Terry. @drf255 bought some 87 choke plates and was going to bore out some 120 carbs to 87 size. He would know better than me though.

Gotcha, is there any other carb with the same dimensions as the 87 that could be converted? There might be a cheaper alternative that just needs a small tweak with a spring, jet, nozzle or whatever.

Yes, if it is a 7 digit number on a black plate.

All 262s have a black plate, but not all have a 7 digit number (9 digit numbers started around 1999 week 18 or so, and many 262s were made after that).

Have you seen a gilardoni?

I have.
