Hi all.
This is my first post on this site, and (of course) it's a question.
I've been lurking around a bit and searched a lot!
I got a Stihl 020 AVP Super EQ from my dad a year or so ago. He said it ran great when he used it last, but it hadn't been used in a year or so prior to that. I tried to start it, but no luck. Wouldn't start.
As I didn't really need it at the time, I put it on the shelf thinking to have someone look at it later. (At that time I didn't fix stuff like this myself.)
The opportunity to have someone look at it presented itself and after the mechanic looked at it, he said there wasn't a chance he could get it going. I took it home and put it back on the shelf. Now I've decided to give my old teachings (my first education was as a car mechanic) and want to see if I can get it running.
Here's what I have so far;
I've managed to get ignition (the guy who looked at it had the sparkplug at almost 1mm gap, and it should be .5mm) and it sparks great.
I haven't taken much covers off it yet, but the lines I can see looks OK.
Trying a cold start by just dumping mix in the carb and a touch of starter-gas it fires right up and runs great with that little mix, then stops. This sounds like it can't get mix from the tank. (I've dumped out the old mix that was in it and put in fresh mix.)
From my limited knowledge it sounds like either a blocked line or the diaphragm is shot. Should I just take it apart and rebuild the carb?
Also, I've noticed there seems to be a screw missing. It's a hole marked LA (seen in picture attached). Haven't got a clue what this is, as I haven't found a manual.
From what I've read the carbs on these saws can be very .... to get running good, but as can I assume it's not much cleaning needed as it runs great with the mix I give it?; and that it's probably just the pumping that needs work/replacement?
Sorry for such a long post, but as I've read around, you guys like pictures..?
NOTE! The old red saw you see in the backround is a very old Jonsered saw (I have no idea what model it is, as the markings were ripped when I got it). I've taken it apart and fixed the ignition but the carb had a cardboard-like diaphragm and I haven't a clue as to how I'll find spareparts.
