    Took my engine off and looked down the intakes out of curiosity. saw something blocking the intake. seems like flashing. Am I right in guessing I need to remove this? Or does this belong there? Its in the # 2 intake port where the vac. line goes. Question 2 How do I get it out?

    yeah, it looks like casting flash to me, too. You'd have to be really careful trying to get that out......you don't want any pieces to get caught and sucked into the valve.

    I'd say there's probably more than just that that you need to take care of, considering the rust thing that you got going on there. I hope that the pic is more an illusion from light coloration, but it looks like everything is rusty on my computer's image.

    Nothing really abnormal. I see the intake valve and some carbon build up onit. Turn the engine over by hand and you will see the valve open and close.

    The light isn't good. the gasket is on the outside yet. the inside is silver. wanted to repaint it. then saw this. didn't want to take the heads off. might have to though.. Gotta do valve lash, might as well. wondering if this would damage anything being choked off like this.

    You don't take the head off to do valves.

    After looking at the pic several times I can see it now. Looks like leftover from the casting process. Here is what I would try:
    -Rotate engine to close the valve, You don't want any metal falling into the cylinder.
    -Try to put a rag behind the obstruction to catch any pieces.
    -Using a small needle nose plier pull out as much as you can. Use whatever tool necessary to break off pieces and get them out . Try not to loose any. Don't use any sort of drilling or grinding tools. They will make debris you cant remove.
    -Blow out with compressed air.
    -Remove the rag.
    -Blow out with air again.
    -Check with light and mirror to see if all the pieces are gone. If not blow out until they are gone.

    SHOP VAC. Flashlight. As above, rotate motor until valve is closed, then poke at it. Suck up any debris with your shop vac; you may need to fashion an appropriate "nozzle" from a hunk of tubing and some duct tape.

    In addition to the Shop-Vac:

    Triangular needle file, coat with silicone grease. Use it as a die knife, inserting the file PAST the flashing, then file/draw backward while vacuuming.

    The silicone will catch any small particles and the Shop-Vac will catch the larger ones.

    CAUTION: Do NOT file toward the valve, only away from it.

    I think I'd like to see a better picture before giving a comment.

    I'm not really even totally sure which part is being commented on.

    I've marked two bits as a 'jagged edge', but it might just be shadowing.

    Port-out the Chamber.

    Use a DREMEL with the Flex-wand Extension.
    A Small-diameter, Med-coarse, Sanding Bit.
    Hammer flat a length of tubing.
    Hook the end to act as a shield for the Valve Stem as you Port the Chamber.

    Remove the Imperfections.
    Smooth-out the surfaces with a sanding drum of finer grit.
    Vacuum the chamber when you've finished

    The pic you marked is correct Gregg. The opitcal illusion is my broken mag light. Have a dremmel didn't think it would fit. gotta check out the flex wand. Didn't think the shop vac would get everything out,but I get what you are sayin with the smaller end.
    Thanks for all the ideas. All I got at work was Good luck man. :D
