    New plugs installed and no more backfiring. Thanks to Bertsmobile1 for all the help.

    Toro Backfire on Cold Startup

    My neighbor loves me because I do the same and usually run out of grass so I cut his.

    Toro Backfire on Cold Startup

    Ah! I get it now. I was only considering the hot muffler as the ignition source and not the HOT exhaust from the first ignition. I'll get the new plugs installed and see if I can replicate the issue. As you know better than anyone, troubleshooting an intermittent problem can be difficult...

    Toro Backfire on Cold Startup

    Thanks for the quick response. Not sure what "afterfire" is. My understanding is that "backfire" is fuel being ignited in a hot muffler. Since the engine is cold, it can't be that. The 2 times I was able to replicate the issue, it backfired immediately upon starting the cranking. I have...

    Toro Backfire on Cold Startup

    Hi guys, I'm working on a Toro zero turn (Model 75755) with a Toro branded engine # 139-0602. The complaint is that it intermittently backfires on a cold startup. It runs fine once started. I have only been able to replicate the issue twice and both were on a stone-cold engine startup. It...

    GX270 Kickback

    Update - the pressure washer started fine for a while but recently started kicking back again while trying to start it. My buddy ordered a new ignition coil and set the gap back to 0.010". No change with the new coil. Still kicking back. I think I need to order a book of matches and some...

    GX270 Kickback

    My buddy picked up the pressure washer today and will keep an eye out for these issues. If they appear, we'll order a new magneto and go back to 0.010 gap. Thanks again for all the help!!

    GX270 Kickback

    SUCCESS!!! Bertsmobile1 win the prize (if I had a prize to give away). I had the original magneto gap set at 0.010". I set the gap to 0.020" and it jerked out of my hand at 1/2 of a pull. I set the gap at 0.030 and it starts every time and runs great. I wouldn't have ever figured that out...

    GX270 Kickback

    That's a great idea! I'll try that today after my bloodmobile donation appointment. Thanks!! I wondered that myself but if I disconnect the spark plug, I can pull it over all day without any kickback. As soon as I reconnect the plug, it kicks back when I try to start it. That points me back...

    GX270 Kickback

    Thanks Bert. Looks like mine is advanced about that much but I still haven't figured out why it's kicking back. I put it all back together today and it started twice with one pull. Woohoo!!! On the 3rd start, it snatched the cord out of my hand again. It's just teasing me now. Dang it!

    GX270 Kickback

    Thanks to all for weighing in and giving me some things to try. Still stumped though. Looks like I need to tuck my tail between my legs and tell my friend I got my butt kicked with this one. Unless you guys can reach a little deeper into your bag of tricks one more time, I'll admit defeat. :(

    Can't remove emulsion tube from Honda GCV 160 engine

    I'll put that in my bag of tricks next time I have one stuck. Good idea!

    GX270 Kickback

    I took a screenshot of a youtube video by Autotech (thanks Autotech) of him removing the flywheel from a GX390. It shows the magnet at about the 12 o'clock position and the piston down about 1" in the bore. With my GX270 magnet at the 12 o'clock position, the piston is at TDC. If I put the...

    GX270 Kickback

    Yes, the spark plug was out and I verified that the piston was at TDC. It really has me stumped. Do you think a new coil can compensate for the flywheel being off that much? I didn't measure it but it looks about 30 degrees off to me.

    GX270 Kickback

    I can visually see the compression release mechanism burp the exhaust valve when I have the valve cover off and turn it over by hand. It also doesn't kick back at all if I have the spark plug disconnected. As soon as I restore spark, it kicks back on the first pull.
