good luck... but your number says craftsman all over it. have about go to sears and type in that model number... your Tecumseh number would be like an LV160 or something similar

goggle that , there is too much info to help you if you cant see that

If hose coming off carburator does not connect to anything then it is the over flow for carburator when float gets stuck and does not close needle valve causing excess fuel in carburator bowl and is drained automatically through vent orfice connected to hose that gas is dripping from. If this is the case then remove carburator bowl, check float, needle valve and o-ring in where needle valve goes. sometimes when carburators sit over winter with gas in them the gas breaks down and over time will gel/harden and cause float to hang up and o-ring for needle valve to deteriate and not sealing properly. clean and replace parts as nessesary.
I hope this helped.

unfortunatly there arent any diagrams, my best advise would be to install the fuel lines leaving excess to trim off as you route them betwixt and between. remember that the fuel lines complete a circuit and that the primer bulb does not pressure up the carb, all it does is circulate fuel through the system and makes a loop

hope this helps and good luck

use this link to contact karcher, they will email you a diagram.

The smaller diameter line (fuel supply) goes from the fuel tank (w/filter) to the carb body. Another larger line (purge line) goes from carb body to the right nipple on the primer bulb. Another large line (return line) goes from the left nipple of the primer bulb into the fuel tank. co0mpleting the purge circuit. This info pertains to my 2006 Craftsman 32cc with Zama carb.

go to sears website you can find any diagram u want once u put in the model number
