I prime the carb then then start but engine dies after running very briefly was told might be fuel filter but cannot find filter; wonder if is in tank itself or in line as it enters carb? Seems like other posts indicate possibly carb needle is cause ?
Could just be dirt in the carb.
The main jet is the bowl nut and they can clog up with dirt.
Give it a good clean.
Some tecumseh's do have little metal filters that are in the fuel pipe themselves.
Take pipe off and try a see if a screwdriver go's all the way.
If not a filter will be in there so try and push it out but id clean carb aswell.
