    Yeah, you can't really tell until you sit on the bike.

    If you have 'slat head', meaning the spark plug does not go strait up, the best plug you can get is an NGK 5944 (BPR7HIX) Iridium spark plug.
    You will will not have to mess with again, and why I put them in all my new builds.

    Will 79cc four stroke need a bigger or smaller jet size than a HT engine? Looking to reuse my NT carb.

    Thanks KC. I still can't get my 80 cc to start, I tried everything I could think of, except check the woodruff key. How do I take off the magnet? Will I just use a puller for that? Thanks
