    well first off, im totally happy with my motor and this awesome froum, very very helpfull, thank you!
    but now another sitution has arised! my motor is new and not even 10 miles on it yet, but it seems when im going full throttle or some time even when im on the way to full throttle the engine, boggs down seems like im not getting my engines full potential.... could just be a simple adjustment? or maybe its just the motor breaking in? any clues or tips.....and also it when i put the choke on the engine will just cut out..
    but thanks for all the hjelp

    Once your motor is running, putting choke full on will usually kill it. I don't have a kill switch, so that's how I stop my motor.

    As for the bogging....What is your gas:oops:il ratio? Have you checked spark plug gap? Checked the color of the plug?

    gas ratio is 20:1 what would be a idle gap in the spark plug? and im not sure what you mean by Checked the color of the plug?

    I would start the plug gap at .020 or .025 with a quality spark plug, like a NGK or Champion. Here is a link to pictures of spark plugs. You run your engine, then let it cool, then take out your plug and that will give you some idea of the ai/fuel/oil mixture being correct. Good luck..........

    NGK B5HS is what most people use. Nobody around here had the ngk (not even advance), so I ended up getting a Bosch plug at Napa. Pretty much any 7 or 8mm wire and boot will work fine. Anything's better than stock I think.

    I use the B6HS I find the cooler plug works better here in Florida, especialy in the summer.

    Your plug should be brown or black, but not too sooty or too oily. You could be too lean or too rich, the plug will tell all.

    well, none of the auto stores around here have that plug, instead of ordering it, could recommend any other ones? they all carry ngk plugs but none of the b6 or b5HS models.....what else would could i pick up..

    Here is a whole thread of different replacements. I get my NGK B6HS from a local marine supplier, you might also try a Motorcycle shop.........Also you might look to see where the clip is on the needle inside the carb, and possibly move it up one slot to try to stop the bogging.....

    Did you have them look up all the equivalents? Napa didn't have the NGK, so I had them look up the equivalents and I ended up with a Bosch. Not sure of the number.

    Go to a marine store:

    Boaters world, West Marine...If you have them where you live. These plugs were used in 60's vintage Evinrudes.

    Napa auto parts usually has a better selection too.

    AutoZone has the NGK's. So do most any bike (motorcycle) shop.

    That plug looks good to me.

    The top of the carb needle is the flat side. The point is the bottom.

    Check to make sure the wire is screwed into the CDI tightly, maybe take it off cut off a 1/4" of wire so you are getting a good connection. Also on the spark plug end, and inside the cap mine has a screwdriver slot, so you can take it apart, make sure that is tight..............
