    when i did replace the pickup line(witch whas totally deteriated, half of it whas gone) i did remove the tank and cleand it. as far as i can tell i have plenty of gas going to the carb right now. when i said the filter is full i meant its full of clear gasolin the rubber fuel line is bulging a tiny bit from presure but i will but a guage on it to veryfie the presure this is why i dont get whats up with this car i have tryed a lot of things finding things and corecting it but it still akts weak like im starting on high gear where my shop is ther is a bit of a clim uo to the road when i get going on flat ground its ok but when i start to climb i need to add more gas thats when it chokes up and dies unless i really give it some gas i might make it up but there is no midrange power
    i have messed around with cars for many years but this is something ells

    Hans, sorry for my mis-understanding. Pat mentioned the possibility of the outer ring on the dampner slipping, or the pointer being off from true TDC. There's a slick method of verifying TDC that's been posted a few times, but either I don't understand our search engine or the search engine is really, really bad here. This is the most accurate, non-invasive (nothing poked into the cylinder to get jammed) method I've seen:
    1. Make an indicator from some clear plastic tubing, a jar of light oil, and an old spark plug.
    2. Break up an old spark plug and attach a length of clear plastic tubing to it make it airtight. Silicone will work, but so will hot glue and it's quicker.
    3. Remove all the spark plugs.
    4. Stick your thumb OVER the #1 cylinder spark plug hole. Rotate the engine with a socket on the dampner bolt until you feel pressure on your thumb. That's the compression stroke.
    5. Screw in the spark plug with plastic tubing attached and insert the other end of the tube into a jar of light oil. Continue rotating the engine. Bubbles will appear until the piston reaches the top of its travel. When it starts down on the next stroke, the bubbles will stop and oil will begin traveling up the tube. Stop at a convenient point and mark the tube. Then mark the crank pulley and the engine body at a convenient spot.
    6. Rotate the engine backwards and watch the oil recede into the jar. Continue rotating. As the piston continues past TDC and downward it will again suck oil into the tube. Rotate the engine till the oil again reaches the mark. STOP! Mark the crankshaft pulley where it lines up with the mark you made previously on the engine. You should now have two marks on the crankshaft pulley. The midpoint of these two marks lined up with the mark on the engine is TDC.

    If your dampner is good the "new" TDC you mark should align perfectly with the line cut in the dampner ring, and the pointer should be aligned.

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
