Hi Everyone. Pretty new to karting and working on my trouble shooting skills. Kart ran well last year. Came out this year and cannot get it to stay running. Runs only for a few seconds and dies. Here is what I have checked and done so far. Replaced spark plug, float bowl is receiving gas, removed carb and jet and blew out. Tried choke at different positions, Engine has the following modifications: Larger jet, stiffer springs, removed governor, header, spark plug. Engine has stock gas tank with holes drilled in cap. Thank you
