Need some help with a hedge trimmer
Posted July 24, 2011 - 12:26 PM
When I got it I gave it about 30 pulls and was able to make it run for about 5 seconds and that was it, so I figured it was a fuel issue and ordered a carb kit. I put the kit on today and it wont fire at all. I took out the plug and put a few drops of gas in and it still wouldnt fire! Its getting a decent spark so I have no idea why its not firing. I even took the muffler off and looked if it was plugged, but it was clean as a whistle.
Any suggestions appreciated

If the port looks good try to start it without the muffler on.
If it starts you have too much blow by, needs a cylinder, piston, ring kit.
Learned this back when I worked at the landscapers on all the 2 stroke stuff, quick and easy way to tell if the motor is good.

I think you hit the nail on the head when you said it was getting blow by. When it runs it seems like it lacks power to stay running.

But the fact that it fires eliminates ignition trouble, you just need to decide if the carb is good. I'd say the is motor is well on it's way out.
Most of the small 2 stroke engines are Aluminum bore, some are chromed, either way they don't last long.

Might check the fuel lines, they don't seem to last long anymore.
I replaced both

I finally dried off the plug and ran a LP bottle into the carb and started pulling. Eventually, it took off and has started good ever since. IDK what it did, but it helped. Even seemed to have more power afterwards, so I must've knocked some dirt loose or something.

I think I have come to the conclusion that the motor is worn out...... I tried putting the muffler back on and now it wont even fire!
The muffler on a 2 stroke causes back pressure, without the muffler there is less back pressure and less blow by.
That's why a engine that has some blow by, is hard to start, or won't start, will fire with the muffler removed.
Remember a 2 stroke uses exhaust scavenging to help draw in the air-fuel charge to run, tuned exhaust expansion champers.
Even though you engine doesn't really have that, it still factored in in the design of it.
