After removing the carb, disassembling and blowing it out (twice) to no avail, got a one gallon can of Gunk Parts and Carburetor dip. Removed the carburetor (again), removed float bowl cover, gasket, float, and needle valve and soaked it in the cleaner for several hours. Blew it out (again) and reinstalled it. Now generator starts on first pull like new!

Remove the air filter and squirt a little gas into the carburetor. If it starts and dies, you'll know it's the carb. Probably varnished up from old gas. ALWAYS use fuel stabilizer in a generator

Engine will not run, but will start with a starting fluid. I have changed the spark plug, air filter, oil, and fresh gas.


Sound`s like your not gettimg fuel. 1 take fuel line loose from carb. (have a bolt handy to plug gas line unless the gas is old then drain gas into a suitable container for disposal.)2nd take fuel bowl off of carb. should be 1 bolt thru the bottom holding the bowl on. Be carefull not to tear gaskett. Float assy. should drop down,but should not fall out. 3rd take aresole can of carb. cleaner with the straw attached and clean the float bowl, the float area. watch for over spray onto painted area,wear glasses to protect eyes. wipe off overspray as soon as possible.4th clean jet,place straw i,nto small metal tube that looks like a part of a metal inkpin located in the center of the float comming up from the bottom. 5th,open the choke/throttel plate inside the large opening in the carb and spray that area if you can see any metal trubes in that area place the straw into that and spray.Re assemble in reverse ordear that you took it apart. Be sure to pay attention to the gaskett or you will have leak`s. rre fill with fresh gas should start and run. If you do not use equipment every week then you may want to put a gas additive into the gas tank to help prevent this from reacureing. I use a product called Sea Foam Good Luck

My generator won't start. I started it when I first got it about a year ago. It's been in my garage for about a year.


Remove and clean/check/replace the spark plug first, spray some WD-40 in the cylinder, Remove all old fuel and just fill with enough fuel to run it. If you are comfortable removing the carb then it should be dipped/cleaned. Check to ensure the kill switch is not engaged/unplugged. Lemmee know then we can go further!

11 hp 5700 watt generator wont fire


If you could not start in spite of oil and gas change, checked gas supply, spark plug, ignition cables and coils (magnetos) and so on whitout success, then try this:
Your generator has a low oil level protection, which stops the ignition of the motor.
After "a couple of years" sitting without or with old oil, the level switch may have got lazy or stuck down.
If your oil level seems to be good, while measured, find the oil switch and try to shorten or disconnect it.
If you succeed in running the generator change or repair the oil switch.

I hope that this will be helpful, because I don't have your device in front of me, but some people rank such an answer with 2 thumbs, which means useless. Better dont rank.

String trimmer only runs with choke on


If you have to run with the choke on, it's having problems pulling gas thru the carb.
Start making sure that you're using fresh gas/oil mix. Don't attempt to use last years leftover in the tank or a spare can. Bad news... won't fire well.
Second, pop the carb lines off the carb and flush with carb spray cleaner (use the nozzle tube that comes with the can).
Third, check for cracks, breaks, leaks in the supply and return hoses. Replace any damaged hoses.
Disconnect the carb from the engine and spray all jets, orifices with carb cleaner (I like the Berryman's B-12 spray) and reinstall.
Also, pull the filter out of the air filter and clean, reinstall.
While you're at it, pop the spark plug out and clean the tip with carb spray as well.
Finally pour in a fresh gas/oil mix...start as usual. should be alot better!

Mantis 2-stroke tiller won't start


This could be one of several problems...
• Last year's fuel. Get some fresh gas.
• Every 2-stroke needs a new spark plug each year... you know what that means.
• Clogged carb jets due to storing the tiller over the winter with fuel in the system. Never, ever do that. Now you'll need to pull the carb apart and clean it. Most of the orifices are so tiny you can't see them. Good luck.
• Engine is so old the crankshaft seals have hardened with age. This is one reason no 2-stroke lasts longer than about 8 years. If the seals are shot, then it will cost more to fix than a new one costs. Time to toss it.

Just won't start


check the spark plug after a failed attempt to start. If dry, then no fuel is entering engine.
Did you leave old fuel in carb? if so, your carb probably is dirty: old gasoline deposits varnish, gum, and you will need to dissassemble carb and clean it.
