Hello, I am a little puzzled with my D 19 gas. I put new points,plugs, condenser, wires on it last fall. I have used it all winter to feed with, and had no problems with it starting. Today I couldnt get it to run at all, didnt even try to start and the ole girl has always been easy starting. I checked the points etc, and seem to be getting fire, and gas. Could it be the fuel pump? I need the help of the experts to send me in the right direction. I thank you in advance for your help, and for the help in the past. Rodd |

| Rodd I would pull a plug or 2 and turn over to see if they will fire while grounding the side of plug to block. Then I woulld see if they looked wet like if they were getting gas. |

If you're certain you've got spark, and the carbeurator is passing fluid, that the reason for no-start would be that the float bowl is full of condensation, rather than fuel. One way to check for this possibility, is to put a shot of ether into the intake, and if it pops, drain the carb out into a can for a minute or two, until what's draining smells like gasoline... then try starting it again... it'll probably go. What frequently happens, particularly with ethanol blended fuels in vented tanks, is that the tank 'breathes' during fall and winter temps, and inhales damp air, which is then absorbed by the ethanol (ethanol is hygroscopic). Due to it's specific gravity being higher than hydrocarbons, it falls to the bottom of the tank, as well as displacing fuel from the fuel line and sediment bowl. By draining the bottom of the carb bowl, anything in the fuel line and sediment bowl gets cycled out, leaving the fuel ready to go. Another important thing to realize, is that ethanol doesn't 'mix' with gasoline, it's in suspension. If you put a quart of ethanol blend in a bottle on your shop shelf for six months, you'll see it 'layer out'... where the bottom layer will be water, the next layer will be saturated ethanol, then ethanol, then gasoline on top. This is the reason why folks experience engine problems due to ethanol... when the ethanol layer gets drawn in, it's 100%... not 10%. Best to drain off the bottom into a can and give it another try.  |

Dave, and Dana thanks, I was thinking along the same lines as you both were. I have had a problem with condensation in the tank etc, used some fuel treatment and it helped. I was also thinking could there be a dist problem? Maybe a worn gear Thanks Again Rodd |
