After reading the review on 120 point me I could not ck mine fast enough. I had 3 the same and 1 different. I found my little rc car wrench that fits this sort of thing and used it to spin the bolt out on the 1 that was different. once the bolt was out I was able to pull the crank off with my fingers and turn it 90 degrees to match the others and re install it. After the bolt was back on and snugged up it looks like every thing is cool. test ran the engine , works fine [just like before] this took about 2 min. Could have been done in 1 min. if I had known how simple it was.---Phil
