Stihl 075AV Original Carburetor Adjustment???

[Tapio]

I am having trouble finding the original carburetor settings for my Stihl 075AV. Does anyone know what they would be??? If anyone has a manual, it would be posted in there.

Thanks.

What the Tilly carburetor model number?

I'm 95% sure they still used a Tillotson HS series, so start at 1 turn CCW out on Low screw, & 1-1/4 out on high speed screw (both from fully CW seated).

Thanks!

Hey, sorry I have not responded, I have been insanely busy! Thanks for your input! As soon as I get a spare moment, I'll look at what type/model carb it is.

Your 075 carb is going to be a hs-60 tillotson. Those carb settings sound about right to me.

Thanks for posting the manual, very helpful.

Yep that Tilly is an HS and as stated above on adjustments will get the saw running and fine tune from there. Let us know how the adjustments went.

Final setting of the H should be tuned "in the cut".

I'm having a heck of a time trying to get mine to run right.

I think I have/had a plugged high port. I've messed with H adjustment. The adjustments were 1/2 turn on H and 2-3 turns on L.

I've tried the 1-1/4 H and 1 L, but can only get it to run with the choke 75% closed.

Any advice would be appreciated.

Hello!

I had a similar problem and not founding a manual for the saw, tried some other saw's settings. But then I found out that the TS760 is the same engine wise, and in that's manual, the base settings:
H 1/2 (!) CCW
L 1/4 (!) CCW
Which sounds way too lean. I started at one turn but that was so rich that the saw 'four stroked' when I used it. I ended up close to this (H) value.

Thought I read somewhere the carb has a governor built into it to. Not sure where I read it but worth looking into.:msp_confused:
