Good evening, and appologies if this has all been asked before recently
I got a second hand Stihl Hedgetrimmer (HS61, if it makes much difference - the advice I am looking for will be the same I guess for all 2 stroke engines)
Came as sold as seen, and they couldn't get it working after it had been sat in the garage for a while. Silly me reckons I can do better and failing that my local dealer will take a look for a few ££. So far I can't do better.
So:
- The spark plug sparks OK and looks new (it might have been replaced recently)
- There is fuel in it (ruling out the obvious, and the fuel is fairly new, my chainsaw works well with it still)
- Trying to start the engine and it makes the purring noise as it moves (not sure if that is the technical name for the noise it should make?) - nothing unusual. A decent amount of resistance to the pull cord so I guess compression in the cyclinder is OK
- After turning the engine over the spark plug is wetted with petrol so I guess the fuel lines are OK and the carb isn't blocked?
- The choke works OK, opens and closes
- The mesh over the exhaust outlet was pretty black when I got it, I've cleaned that up
- I need new air filters, trying to start the engine with no air filter (in a clean environment) and nothing
- After a while pulling to start it, petrol comes out of the exhaust, guessing the engine is flooded by then?
- The cutting blade is off ther machine (just in case that and the clutch was jammed)(Oh, clutch isn't jammed on)
- It has run on twice, once at 11:00 last night, and I turned it off after a couple of seconds thinking better - The Boss and The Boys were in bed upstairs (OK, I know I should have been in the garage but I had a film and the fire on in the living room). And again for a couple of seconds today before it died
So as far as I can tell, fuel is getting into the cylinder, the piston moves freely, air is getting in, there is a spark, and some compression.
Where am I going wrong? Not thinking it is too serious to fix
thanks in advance for any help
