![]() ![]() Replacing the rewind spring is often all that you need to do, although, sometimes, it can be easier to replace the entire recoil assembly.įinally, problems with the fuel filter may be to blame. When you try to start the hedge trimmer it is the rewind spring that makes it possible to recoil the starter rope and start the engine. Issues with the rewind spring can easily prevent the hedge trimmer form working. Cleaning out a clogged carburetor is easy, but, sometimes, replacing the entire carburetor is the only way to take care of this problem. I guess it is sparking under compression (at least some of the time) and there is some compression there some of the time.Another common issues is that the carburetor on the hedge trimmer may be clogged, which means that fuel can’t travel through the equipment to start the hedge trimmer. ![]() Tried again, skinned my finger (see my next post, first aid for daft sods playing with hdgetrimmers), few pulls and a cough.ĭid the same by pouring fuel direct in through the carb. So put a bit of fuel in the direct cylinder (saw than on another site), with the exhaust and air intake cover (and filters) off, a few pulls and it coughed - which I didn't expect. Took the starter assembly off and some of the housing to see the flywheel - again all looked good, looks to turn as it should, no wobbles etcĪlso took the air intake housing off to clean lots of tree out from behind it Turning the engine over and the piston moves smoothly and no sticking poiints. So I guess the piston and cylinder is OK. So tonight I had the exhaust assemble off and looked in the cylinder - all looks good, smooth, and as it should be (while I was in there the exhaust got a good clean too). Where am I going wrong? Not thinking it is too serious to fix 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. And again for a couple of seconds today before it died 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). The cutting blade is off ther machine (just in case that and the clutch was jammed)(Oh, clutch isn't jammed on) ![]() After a while pulling to start it, petrol comes out of the exhaust, guessing the engine is flooded by then? I need new air filters, trying to start the engine with no air filter (in a clean environment) and nothing The mesh over the exhaust outlet was pretty black when I got it, I've cleaned that up 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? A decent amount of resistance to the pull cord so I guess compression in the cyclinder is OK ![]() 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. There is fuel in it (ruling out the obvious, and the fuel is fairly new, my chainsaw works well with it still) The spark plug sparks OK and looks new (it might have been replaced recently) Silly me reckons I can do better and failing that my local dealer will take a look for a few ££. 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)Ĭame as sold as seen, and they couldn't get it working after it had been sat in the garage for a while. Good evening, and appologies if this has all been asked before recently ![]()
