Hi,let's see if we can work together to get to the root of your problem! will try my best to help!

Remove spark plug, and with spark plug grounded to the metal of engine crank and see if you have spark. If you have spark, pt a teaspoon of fuel into the spark plug hole, re-install spark plug and see if the engine will start for a few seconds. If it does, check the fuel solenoid in the base of the carburetor.

Has to be a loss of spark or fuel.

Curtis, thanks, I'll have to try this in a couple of days, raining and I can't get it inside at the moment. Could it also be a ground wire? Just throwing things out there at this point.
Expert:  Curtis B. replied 1 month ago.

I doubt ground wire, and with a twin engine, more likey a lack of fuel.

Ok, just checking, when it stops raining I'll look at the fuel and check the spark on both cylinders. It very well may be a fuel starvation issue...Thanks
