Easy way to clear a flooded engine is to remove plug turn off fuel hold the throttle wide open while pedaling or remove the carb if you want to and pedal the bike with the clutch out so engine cranks over while pedaling you should not need to go far 50 to 75 ft. should clear it out. Put the carb back on if you took it off I got a little ahead of myself. with the carb still off turn on the fuel make sure its not running out of the float chamber due to a stuck float. Turn off the fuel, drain all fuel out of the carb either by taking off the float chamber or turning it upside down until fuel stops running out. If you take the float chamber off you can see if the main jet is plugged check my post on the carb to find this info.Use air or carb cleaner only to blow out a clogged main jet never use a wire it will screw up the hole.
Ok you got to make sure you have a good spark test it before puting the plug in the head. Get the carb back on. leave the fuel off pedal bike with the plug in let out clutch it should not fire but if there is any fuel in it it might fire hold throttle open about half. Now that your good and tired spray about a 1 sec shot of carb cleaner or starting fluid in the carb you will have to have the aircleaner off for this. lacking the carb cleaner or starting fluid remove the spark plug and pour in the cylinder about 1/2 teaspoon of premix fuel put the plug in and it will fire up if its going to run at all leave the choke off for all this. This is a lot of trouble but not hard to do you should really not need to take the engine apart to clear a flooded engine I told you this to eliminate a problem due to the carb that might be causing your problem. If you know for sure you got a good blue strong spark and a little fuel it will go. Let me know we will either get it to run or put it in to low earth orbit sound good to you?

Listen to Norman my friend..... If anyone can make that engine run he da man....

I'm rereading your posts and it looks like peeing on it won't hurt. Might be whats needed. Take off the air cleaner so you can see how the choke works. Try flooding it with the choke on them take the choke off hold the throttle wide open pedal the **** out of it you should hear the engines piston going up and down if not you got other problems. With the throttle wide open and pedaling it it should fire. Like one of the guys said dribble some fuel in it. Change to a different plug, and gap the thing close go as little as 0.010 if you have to take off the wires to the kill switch until you get it worked out. What your saying don't make since if its got fuel air and spark its got to fire. If it don't send me the thing I'll work some of my VOODOO on it. as a last resort the SOB engine

Spark at right time.
Fuel-Air Vapor.
Compression.

I have the carb assembled as in the "right" diagram. I have good compression. I dont know what the spark gap is but I will try to find my gap tool tomorrow and check it. I had a motorcycle mechanic friend of mine over tonight to take a look at it and he is as baffled as I am. I kind of hesitate taking the head off but Im running out of options.

Thanks for all the suggestions...

Pulling the head would be my last resort. Okay this is a one in a million shot but I once put plugs in a 57 chevy six and it only fired on five. I did everything I could think of until I finally pulled the plug and looked at it closely. It had a hairline crack in the insulator. Just enough to short the plug out. Take a look it can't hurt.

I wonder if the choke plate is stuck. That will also do it. I have started many a car in a restaurant parking lot on he first cold day because somebody's auto choke got stuck shut. Have you tried just disconnecting the kills switch entirely. If that is faulty nothing will happen.

I would run the idle screw in all the way then back off three turns
disconnect the kill switch
turn on the gas
tickle it half a dozen times.
set the choke on full
Open the throttle all the way
find a long downhill stretch and just go like **** and drop the clutch and keep peddling.

Even if it doesn't start it should sound like its running. If it doesn't you might have a compression problem.

This is my latest swag appraisal..... scientific wild assed guess

When I drop the clutch it is a lot harder to peddle and yes I have compression.

Thanks for your reply

but does it make an engine sound like its running but isnt

deacon · #**130** (**permalink**) 03-11-2008, 01:00 AM

I had to try this to find out mine was stuck when i first screwed it up. Had to pull the plug, drop a long dowel in, then turn the engine to see if the dowel went up and down as the piston moved.

that would for sure answer the compression issue. Unless the head is cracked which I highly doubt. My guess is still the wiring somehow. I think a long pencil would work as a dowel.
