Carburetor adjustment tool for Ryobi String Trimmer

myminifactory

Warning: Work-in-Progress thing. Many Ryobi gas-powered string trimmers develop an issue after several years of use causing them to bog down at part throttle and die at full throttle. This condition can be easily repaired by adjusting the Carburetor. Unfortunately, here in the US these units are required by law to be fitted with tamper-resistant carb mixture screws. Thousands of perfectly good tools end up in landfills and scrapyards due to a misguided effort to save the environment. Special screwdrivers to fit these tamper-resistant screws are available from many sellers on eBay. This tool is an alternative to purchasing these proprietary tools. It should fit a plethora of Ryobi and Homelite 2-stroke and 4-stroke engines. V2 includes several changes based on destructive testing. The body has been thinned so no sanding is required for a good fit. The pip has been made sharper to work with both slot and notched style screws. The handle has been extruded into the shaft for added strength, and it's now slightly shorter. V3 adds a pointer arrow on the handle for ease of use. This tool will be extremely weak if you have your slicer set to align all layer transitions. It performs much better with randomly distributed or vase mode settings. Unfortunately, this tool may not fit every carb out there. I apologize if it doesn't fit yours and would appreciate any feedback so I can make necessary adjustments.
