Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, the accelerator pump rebuild kit can be found here and the carb kit here, double check against the pictures to make sure the fuel bowl gasket matches.
Just let me know if it doesn't match, most all of these late model 6100's do use the kit I posted with the exception of a few that have the different fuel bowl.
To make sure it's the carb what you will need to do is check for spark when the engine is hot or try to start it after spraying some starting fluid in the air cleaner. If spark is not present or it doesn't start with starting fluid you'll need to look into the ignition system.
The test above with the starting fluid will confirm. Once it runs for the 3 minutes and shuts off try using starting fluid. If it does crank its a carb issue. If it doesn't crank it's ignition related.
