Hey guys its been a while for me here on OldMiniBikes. Anyways, took the bike out today for a bit. Was running fine and then it just started sputtering/misfiring under full load. It didnt stall and I rode it about a quarter mile back home on maybe 1/3 throttle. I looked at the plug and it was a bit...

Mods please delete thread. Problem solved...

OK so a couple years ago I bought this bike from someone off Craigslist. http://www.oldminibikes.com/forum/general-minibike-talk/32492-new-toy-need-help.html It had a Tec. HS35 something connected to the TAV30. Took that off, put on an old GX140 from the 80s and enjoyed it for a lil...

ok so i found out one of my Gx160 motors has no compression. I no longer have any plans for that block. Instead I want to take the carb off and the cam out and install them on the Gx140. Will I have any issues running a slightly bigger carb? Do the cams have the same timing or what are...

6" or 7" that is the question. does size really matter? 7" giving you more low end. :biggrin:

Hello all, I was tearing down my gx140 today to get a a list going for my mini. So I removed the oil sensor and took the governor parts out. I noticed as i turned the crank there was air seeping by the piston into the crank case. i could hear it hissing. Is this normal for these motors or...
