QuestionI have a MTD 5hp chipper/shredder that as soon as you pull the rip cord, it won't turn over. We have done troubleshooting (new spark plug, oil, gas, air filter, etc.) so what else could it be? BTW: it's been sitting for about 5 years. Please give details, thanks.
AnswerHi D,
You will need to determine if the problem is a lack of spark or a lack of fuel flow. Right after it quits, remove the spark plug, reconnect the wire and lay
it against the engine head. Pull the engine over and watch for spark at the plug's electrode.
If good, then try to start it while squirting fuel or starting fluid into the carb intake. If it starts and you can keep it running by adding fuel, then the carb most likely has dirt, debris or gummed fuel inside.
You will need to remove the carb, disassemble it, clean all the small internal openings and blow it out with compressed air. Probe each and every hole with a
small wire. Adding a carb rebuild kit wouldn't hurt either.
Also, check for a good fuel flow at the fuel tank outlet.
Let me know how you make out.
Michael
