Ok, so here is the deal... I did the decarbonization process yesterday on my E140TLCCM as told by tashasdaddy. After doing that, engine wont start. Engine keeps flooding. Checked the carbs and they are full of gas. My thoughts are that the decarb caused some carbon build up to get lodged into the carbs and keeps them open, pouring gas into the cylinder. I put the plugs in and they are wet. Take them out, dry them, put them back in and crank the engine...wet again. I have full spark, very good compression.

What gives?

The de-carbon treatment should have very little if any effect on the carburetors except that the alcohol in SeaFoam can dissolve old gel an possibly clog the system.

Make sure that you have your battery fully charged so that you reach the 250 RPM minimum cranking speed.

You will probably need to service the recirculation check valves as the decarb often gums them up.

Yes, when I removed the carbs, one of the floats was stuck. It has to have been from the decarb, its the only thing i did different. It ran before that perfectly.


Battery is fully charged, and just to make sure, I had my battery charger hooked up a the same time (a SOLAR wheeled charger Model OS6150, which has up to 250 amp starting assistance)

As for the recirculation valve, where would I locate that?
