anyone have a recommendation of a site i can order a good high compression head for my 66cc 2 stroke? i ordered the thunder shark pro racing kit but there was so many things wrong with the kit and the company refused to fix any of the issues so am here asking for some help when i finally got it all put together and warmed it up took it for a ride they i guess used the CNC by like 1/2 a mm to much on the threading for the spark plug i did not over tighten it but now it just pops out of the hole i am using JB-weld to hold it in there atm but really that breaks if i rev it up to high because of the compression in the engine... It has a high compression racing head on it now so i do not want to downgrade to a stndard head id like the same if not a better high compression head so please if anyone has any suggestions let me know
