    Finally a break in the racing drought. Gunnedah 31 Oct- 1st November 2020. With an easing of the travel restrictions Tamworth Drag Racing Club has been able to host a couple of race meetings. The last one was in August but I chose not to go due to impending weather predictions. As it was I chose well. They had intermittent rain all weekend and where I live we had torrential rain and strong winds which blew the wind vane off the shed roof. Not good towing weather especially with an enclosed trailer.
    This time the predictions were better and as I've now got a 7 hour drive on our poor excuse for main highways I was hopeful. The Crew Chief stayed home as she had grandaughter minding duties. We shifted to the country town of Temora back in March so it's doubled the travel time and distance but you do what you have to for a racing fix.
    Slept in the trailer overnight and good weather on Saturday so things were good to go. A couple of gentle runs to suss out how the car would run, and if the driver still knew what to do, and it felt good.
    I couldn't get the 91 0ctane fuel that I normally use so 94 it had to be. Turned out to be a bad choice.
    I won't post too many videos from Saturday as they weren't uploading properly (rusty camera operator) my five runs were between 9.17 and 9.3 with a missed gear 9.6. Car was sounding alright but not crisp but I put that down to a bit of stale fuel in the tank.
    Sunday was qualifying runs and the first run was another 9.199. Still not running quite right.

    Second run I jump in, hit the starter and engine fires and revs it's head off. A stone had got past the mesh screens in the intake tubes and was holding one butterfly open. After careful disassembly of the carby, I was ready to race but missed the qualifying run. It was at this moment I put the 91 octane that I'd got that morning in the tank and went out for the next qualifying run. Engine sounded better and I ran 8.992.

    Because of the quicker run I dialed a 8.95 for the first race and of course I ran even quicker @ 8.944. Back on the trailer and headed home.
    All in a good weekend's racing and nice to be catching up with mates I haven't seen for over 12 months.

    My apologies for the late models in the videos as it's what I race against at this event.

    Youtube has changed it's format so the videos didn't come out right but I'll investigate.

    Fixed it!
    In case anyone is wondering why I use 91 octane fuel it's because I had it on a dyno a while back and the dyno operator suggested running 98 octane. There was an immediate drop of 10 H.P. with 98 but the H.P. came back when putting the 91 back in. These engines had 6.5 compression ratio when produced 70 years ago and this engine is probably around 8.5 so doesn't benefit from higher octane fuel.

    Great vids, looks like a fun meet. Please disregard the fact that I jealously hate anyone able to race at the moment. ;)

    I also knocked off some E.T. when I went back to "regular" out of laziness one time. The long stroke of these old mills definitely does like a bit longer burning gas. :cool:

    Don't worry Dick, your turn will come. I must admit, as soon as I tightened the belts and hit the starter button it felt so good to be doing it again.

    I've entered and it aligns with my swing/r&r so pending no border closures preventing me from getting home and back to work I'll be there.
