 Topic: My 190 gas wasn't running so good this morning
Posted: 11 Mar 2011 at 12:49pm |

Was feeding with my one-ninety gas this morning, and it started losing power intermittantly, smoking a little blackish gray smoke, running a little rough, and hesitating once in a while. My thinking is that maybe has a little bad gas in it or got a little water in the gas, as the wind is blowing about 50 MPH today and it is raining and snowing. Other than being a little cold blooded, the thing hasn't missed a beat in over 2 years, when I got er all tuned up, carb rebuilt, and electronic ignition put on it. There was a lot of frost built up on the upper part of the carb, is that an indication of anything? I'm going to pick up a couple jugs of ISO heet and dump in the gas tank for starters, but if anyone else has any ideas, they are welcome! Thanks, Darrel

Almost sounds like carb freezing up.If it is,there is little you can do about it other than weight for weather conditions to change.When conditions are right,high humidity,low air temp,etc,ice can form in the venturi because of the refridgeration effect of atomizing fuel.Seldom happens but possible when conditions are "right". We had a 59 Chevy with a 283 4bbl carb.Once in a while it would do just as you say.Choke down,dog out,not run worth a crap.Stop,jump out,pop the lid off the air cleaner and the ice build up on the venturies was obvious.Shut it off and let the engine heat thaw it and run like normal.
Adding products to fuel will have no effect becuase the problem is the moisture in the air.

Put a cover over the radiator grill and let it suck air through the radiator...Yea I know the fan is pulling air, But so's the engine and it will get it from where ever it can and the air will be warm enough to keep carb from building up with ice... But you also need to keep your eye on the heat gauge too with rad covered up. Did that to 170 for years and adjust cardboard enough to keep engine from over heating.
For D-17, simply runn anhose from air cleaner stack and up under the hood by ex. manifold,
WD45 just lay a crisco can over intake pipe and it will draw air up around pipe from under hood. Worked even better when had the heat houser on, you stayed warmer too.

Yup you have good old carb ice. Thank the Lord you're on the ground lol. I had a D17 III which was famous for it, none of my WD's or 180 ever got it but the III did a lot.

Thanks for the input guys. Hope that tomorrow is a better day for it, because I'm planning on trying out my new snow blower on it, and I think it's going to take all she's got! Darrel
