stihl 034/036

[Davey83]

Hi everyone, so I just brought a really nice red lever Stihl 034 av super, as this is the oldest saw ive ever owned I was quite surprised at how well it went and cut, it got me thinking what was the power output on this saw so I started looking online for specs
apparently this saw has 4hp and is 61.5cc
the 036 is also 61.5cc but has 4.5hp. does anyone know how they achieved this extra power?
which brings me to my next question, when I was looking at meteor kits for this saw they don't make a specific 034 cylinder and piston kit but its for both 034 and 036, so does that mean that this kit would be built to 036 specs and you could potentially gain 1/2 a hp by bolting it on?
just a thought thats all

Your 034 super is essentially an early model 036, built on the same chassis etc. From memory the older 034 AV had 56cc as opposed to 61.5cc, so the power figures you've seen quoted may well be for the older 034 AV. However don't take this as gospel, I could be wrong.

Personally I'd say just run the saw and enjoy it, if you really want to tear it in bits delete the base basket and check your squish isn't tighter than 20thou, open up the muffler a wee bit and tune accordingly. Or just go cut some wood

sorry yes your right I rechecked the specs and I read that the 034 had 56.5cc....
that explains the output, so essentially the meteor kit would be 61.5cc im guessing and would be a big bore kit for the 034?
I agree I should just enjoy the saw for what it is but I like to tamper with things

The 034 Super and 036 have the same P&C. Power wise the 034 Super and 036 are the same (according to my Stihl 034/036 manual) with 4.6 BHP. They are some of the best saws that Stihl ever made.

I've read on here that the 034S actually had better port timing (or maybe it was port shapes) than the 036.

If your saw runs good and the piston and cylinder are in good shape, don't even consider bolting on an AM top end to gain power.

This being an old saw, unless you know it's been well serviced lately, you may want to consider, swapping the fuel and impulse lines, fuel filter, etc. Maybe a pressure/vac test too, just so you don't wreck it due to an unknown air leak. I've never run an 034, but my 036 sure is a dandy.

Yes, here are ~slight~ differences in the cylinders (part numbers are different) but the pistons and rings are the same. The power ratings and bore and stroke are also the same, and I believe that you can swap the jugs between them (like the 026 and 260).

One thing to upgrade on those saws is the clutch drum and bearing to the larger 360 configuration. The smaller 036 and 034S clutch drum bearings tend to grenade.

good info guys
so from my understandings there is an 034 and a 034 super but there is no difference in outputs? would that be right
mine is a super

ok so I just found that the 034 takes a 46mm piston and the super takes a 48mm
anyways I might just put a fresh set of caber rings in and use it

You could always send it to Doc to get it supercharged. lol
Any photos?

yes great idea, I miss having a ported saw!

Ya, they have the same stroke but different bore.

so if you owned a 034 it could easily become a 'super' then
good little saw though it really is

Smaller muffler on the 034, but that is about the only real difference I think. I do not think that the added power is worth the upgrade though. Unless you score an 034 or buy a scored saw for dirt and need a jug and slug kit. They are good saws. I would not call them little though. My 211 is little. You can run a 25 inch bar on the 034 Super and 036. The oil output is the same as the 361, and the power is about the same, and I run 25 bars on my 361s most of all. But... we have softer wood here than down under. Likely an 18 or 20 is as big as you wanna go on an 034S in gums and red oaks. Crank the oiler wide open. Its adjustable and on the belly of the saw.

The 034S came with the Tilly 43 carb. Do you have that one? Look for the metering plate plastic spacer or the HONG KONG on the plate 0f the carb.

Relatively easy to bump these saws into the 6-6.5 bhp range. Your muffler is an 034 muffler with the heat shield and a muffler spacer. You're best to add an 036 muffler that's non baffled to the saw. Should allow elimination of the spacer.

Thanks for the props Jeff.

I use @Mastermind recipe that he so graciously shared with me.

Randy is the man with these saws.

Lol.

I have an all original 034s that does not have a tilly. It also does not have a muffler spacer. I think the later 036 is what the spacer.

ill post some pics of my 034 tonight

Not all of them came with the tilly, but some did. I've never seen an 036 that came with a tilly.

The 036 doesn't have a muffler spacer. That I'm 100% on. It does have a heat shield and gasket.

I could be wrong, but my understanding is that adding a 48mm jug to a 46mm standard 034 requires the spacer if the original muffler is to be used. If you go with the 036 muffler, it's just a bolt on.

The 48mm 034S and the 48mm 036 jugs do have both internal and external differences, even though the bore is the same. It may only be needed on the 034S jug.

Maybe someone can post and IPL? I have a minty 034S that I've yet to pull apart.

This is the spacer
