Never owned a 30.5 but my 29cc head kit is pretty damn fast. gets to top speed very quicky!! the 29 has lots of torque
TO; splcrazy
I have also 29cc head kit but never works good, I can’t count how many spark plugs I changed, almost 2 every run, and it is extremely difficult to start. I try all possible ways to adjust the carburetor but I Failed. Could please tell me what is your needle setup.
The engine came with WT 668 I’m thinking to change it to WT 603 which is standard carburetor for Zenoah 26cc.. I don’t know if this will work? Any advice.
