New to me Stihl 045AV in superb condition

[Joepro]

Spotted this Stihl 045 AV on marketplace for £20 locally and thought it was a scam. Turned out it wasn't a scam and I was the first to turn up and buy it.

Hadn't ran in over 10 years according to seller. When I got it home I put a little oil in the cylinder before turning it over gently and checking for spark. Strong spark. With plug back in the compression is very strong. Saw has original bar and Stihl stamped chain. Seems to be very low hour saw.



I added fresh fuel and was amazed that on the first pull it fired up and ran. It was late so I only ran it for a few seconds and the next day it would not start again unless I sprayed brake cleaner into the intake. Suggesting a fuel issue.

I would like to check does anyone have a diagram or photos of the fuel hose from the tank to the carburettor please? I suspect there is a split pipe somewhere. I have ordered a new intake boot and impulse hose. But I am unsure of where the fuel hose connects to the carb as I can only see the impulse hose connection. So the fuel line may connect at the intake pipe instead?

Nice saw. Try here for some manuals and such. https://www.arboristsite.com/threads/the-beg-for-manuals-thread.68615/

From searching photos on the interwebs I believe I understand this a bit better now.

There is of course a rubber hose inside the fuel tank. This connects to a metal barb pipe inside the tank.

From there, there is a tract inside the casting which leads to a drilling at the intake port. Therefore there are no further fuel hoses. The intake boot provides the seal between the drilling and the carb body.






Therefore I will rebuild the carb with a kit, replace the intake boot and impulse line. And finally replace the hose inside the fuel tank and fingers crossed that will give it a healthy fuel system to fire up on.

I got it running

I stripped and ultrasonic cleaned the carb. The carb repair kit arrived early so I tried it again without going much further into it. It started up and ran very well. I will replace the crank seals and intake rubber etc as I think it has a small air leak as it had trouble settling back to an idle.

But very pleased to have a running circa 50 year old Stihl saw!

Sounds good. It may not go back to idle without a bar on it.

I would be extra cautious using brake cleaner like that. I ruined a 4 stroke with straight gas in my younger days. Washed the oil off the cylinder and piston and ruined it while trying to get it to go.

there is a small hole on the rubber boot carb flange that has a fuel passage through the fuel tank casting. you will need fuel line & filter and a pair of angled needle nose pliers to install fuel line inside of tank
