Blower getting too much gas

    I have an Echo PB-602 blower.

    A couple of days ago, an employee put regular instead of mixed gas in it. Of course, the piston siezed. It did not sieze bad and I got it turning over really good now. The problem is that it is getting an excessive amount of fuel now. When I pull the rope with the plug out, I can see fuel splashing around in the cylinder. I took the carb off and cleaned it all out - I didn't see anything that would cause it to malfunction.

    Any ideas?

    I know that it is getting spark - I saw it.

    The piston rings will probly need to be replaced and the cylinder bored out.

    The rings are okay. I had the thing apart and looked at them. There was just a small part of the piston that started to melt. They cylinder was not scratched.

    I fixed the problem though. I took the carb off again and gave it a pull and it started - with the carb off. Somehow there was excessive fuel in there - maybe combined with the penetrating oil that I used. After it stopped running, I put the carb back on and no problems.
