Angry (trouble) SHOOTING Orleans

Okay, I am home and here are the results:

All wires appear to be connected properly and tightly.
Carbs appear to be on the engine block ok. All ducts are also attached.
Battery was charged when I started.
With the gas tank on the bike, I had no fuel getting to the carbs. Opened the float bowls, and nada.
Took the tank off and injected 6ml of gas down each fuel line - still wouldnt start, but there was fuel draining from the bowls.

I'm at a loss....anyone else got any ideas?

You did make sure you have spark?
Was there any fuel on the plug when you tried too start?

I did check and have spark at all 4 plugs. Let me pull a plug from each cyl and see if they're dry. I did the spark check in the dark, so may have missed some crud.

Hey, sorry for not calling last night, too. Our client came to the focus group and wanted to chat, so I didn't get back to the hotel until late. I'm sure I'll be in MKE again, though!!

You need fuel, good spark, and compression, for it to fire off.

All four plugs are dry as a bone.
I'm obviously missing vacuum...which could mean I'm missing compression. Anything obvious I should look for for that? I have a compression tester, but none of the leads that it came with is the right size for our bikes. So that's one trip to NAPA.

Remove the plug that is not in the hole of the head, rear left, and see if you can cover the hole with your finger. If so turn the engine, but be sure to have the plug wire away from your hand, and if you feel any push from the air in the cylinder. Oh yes, be sure to unplug the other spark plug.

Yikes! And I guess I shouldn't be standing in water when I do this? Ha ha - let me go see what I can do to myself. Back in a flash. lol


Ow! Yes, it blew my thumb off, so I take that as a good sign?

Yes, good sign.
Did you try to start with the choke on or off??
Can you smell gas in the cylinder??
It may just take a bit to get a good fuel/air mix into the cylinders.
Did you find your water in the crankcase problem??

Are you using new spark plugs? I have rebuilt car engines and have had a time starting them. The problem turned out that I was using the old plugs that had been on the engine. The old plugs would not fire with the new higher compression.

Also spray carb cleaner into the cylinder through the carb or even the spark plug hole and see if you get a fire off.
Spray into the hole and replace plug an try to start.
