My GT-14 (14 hp K series) won't start.

It was flooding bad, so I removed and rebuilt the carb.

After installing the carb I realized I did not install a spacer about 1/4-5/16" thick between the carb and the block. I was told this shouldn't hurt anything.

I have good spark, good compression, and I checked the flywheel key to make sure it wasn't broken.

I have made the initial carb adjustments but can't get this thing to even attempt to start.

It won't even fire on carb cleaner (with fuel shut off).

Any other suggestions?

If it's a points style, flywheel key makes no difference, but if solid state, then it will.  The GT14 I had years ago had solid state ignition.  You said it's been flooding in the past.  Did you replace the spark plug?  Even if it looks good, a gas fouled plug can fool you.  Exhaust outlet clear?

Did not replace the plug, but with it removed from the head and the wire connected, the plug fires great....Maybe I will try a new plug.

Really getting to me!

 

Exhaust is clear.

I've also had similar issues starting an engine.  The plug will be good, spark good, and carb in great shape, but won't pick up fuel.  Almost always, I can pull the spark plug, directly spray a decent shot of carb spray into the cylinder, quickly get the plug back in, and they'll fire right up & do fine thereafter.  Why...I don't know!

I too would suggest a spark plug. I've had that same thought pattern that it sparks good, put it in then nothing. I ended up buying a box of NGK spark plugs to have on hand to be safe. 9/10 times it ended up being the spark plug.

Going to get a plug (or 2) tomorrow....I will let you know the outcome of this issue...

 

By the way, how many turns out would you start at after a carb kit installation?

Usually about  2 turns on the main screw. 1 1/2 on the idle.

The specs for the carb should be in the Kohler service manual. On second thought I think I have a chart somewhere. I'll attach it here. This is pretty handy with the initial settings for all the K series engines.

OK guys, YOU ROCK!!

I put a new plug in the Kohler, shot a small squirt of carb cleaner in the intake, and 3 seconds later it was running well enough that no adjustment of the carb was necessary until it warmed up!

 

I would never have thought that a plug that shows spark could be weak enough to NOT start an engine.

I know better now!

 

This is what I like about this forum....people helping others!

 

Thanks again!

At one time none of us knew that, so don't bad about it.
 
That's one reason that something like this is handy.

It will definitely take out the "guessing' if the plug is working or not.
