Question about McCulloch 13HP 338 Cc Portable Generator # FG6000MK

1 Answer

Almost new McCulloch 7800 won't start.

Decided to pull the generator out today and fire it up. It is basically new and has only been run once for two hours. Pulled the plug and checked it (looked great). Turned the fuel on and pushed the electric start. Would turn over and over but would not fire up. First checked the fuel line and went so far as to blow the whole thing out. Pulled the plug again and squirted some gas into the cylinder. Hit the starter again and it fired up for a few seconds. Appears I am not getting fuel into the engine.

So any ideas as to what to go after first before I start taking things apart. Thanks!

    I thank you for answering my question so quickly. Hey I haven't worked on a carbureted car since high school (30 years). I did pull the carb off the intake just to see if anything obvious stood out. Nothing did and I tipped it to make sure there was indeed fuel in the carb. So with that where is the needle I am looking for in the carb. Thanks again, Kevin

    The carburator float bowl first. See if the needle is stuck shut along with the float in the up position.

This is a typical problem with small engines that are not used often or only used seasonally

The problem exist when it is not prepped for storage properly, meaning that the fuel is not shut off and the engine allowed to burn off the remaining fuel that's left in the carburetors float bowl, causing the un-spent fuel to sour and later creating a condition called varnishing which clogs the carburetor venteries

All of these steps will require the use of skin and eye protection!!!

The solution is to replace the old fuel in the tank with fresh, its not a bad idea to replace the fuel filter at this time, then with the petcock in the off position remove the carburetor float bowl, inspect the gasket or seal for imperfections (replace as needed) and clean it along with the float assy. and piston check valve with a spray type carburetor & choke cleaner and gently wiping with a clean lint free cloth so as to remove all yellowish colored varnish and any debris, before reassembly place a glass or metal catch pan or bowl under the carburetor and turn the petcock to the on position to allow fresh fuel to flush out the fuel line and now LIGHTLY & GENTLY (without resistence) lift the float up, the fuel should stop flowing. If it does not stop, repeat cleaning procedure. If it does turn the petcock to off and reassemble. After reassembly turn the petcock to on, the engine should run.

Another preventive step is the use of a product called STA-BIL fuel stabilizer

Generator back firing from inlet manafold


Your symptoms are from running lean. Foam air filters put debris in carb jets. Check all the carb passageways and jets. Always start with a new plug.

Generator will crank but will not start


First check spark while cranking over( pull the plug wire hold by insulator about a 1/4 inch away from any ground, you should see a strong spark. then check to be sure the fuel is pumping from yhe carb., if no fuel try a short squirt into the carb intake. should fire up if you had spark.Its generally a good idea to put in a new plug and be sure to check the gap.

The spark coil is bad if you have no spark

Small engine repair. Part is expensive.

Have you checked spark for sure?
1) Spray WD-40 directly into carburetor
If machine has spark, it will fire
2) Is exhaust port clogged with carbon and dirt?
3) Get new spark plug
Pull out old spark plug
Put spark wire on plug
Hold spark plug wire with fingers
Put spark plug threads against metal opening where spark plug came out.
Metal to metal
Pull cord or push starter
Look for spark between metal

No spark, then spark coil is bad.

I have one.. great little unit.. very reliable..

1 assuming sparkplug is good / in / /newish??
Fuel needs to be filled.. I suggest premium only (less residue if it sits for long.)
fill oil.. top up..
d/c electric plugs
then
togle ignition switch to on
turn fuel cap to on
turn fuel switch (sw) to on
move choke to start if engine is cold start.
pull starter cord ..
good luck
ps.. I have learned to run engine dry of fuel after use. turn off fuel (sw).. this empties carb.. You may have to pull starter cord a few times with next start to bring the fuel down..

Sounds like you may have a wire shorting out. Check all ign wires and make sure one hasnt rubbed through. Maybe take off your front cover and make sure something isnt shorting out your coil contacts. Hope this helps
