I bought 4 Kazuma,s and I,m having problems starting 2 of them. I changed oil when bought new before I ran them but never heard about this gel pack in carb intill now. Once I get them started after pulling them or burning out starters the ran and start excellent would my problem be coil problem or the carb... Rammer

 

sounds a bit more like a fuel related problem than spark

 

What type of weather are you in. Have you looked at my How to carb tuning tips? This helps most of the starting problems with these chinese quads.

 

I printed out your carb tuning tips, very helpfull and straight forward thanks I,m going to rip the carb of today. Its cold weather where I,m from (Canada) but still I have a problem with these 2 units even in the summer time. But I have noticed these units have to have the choke a little open to run when the other 2 units dont have to so maybe your right with the carb problem thanks RAMMER
