After all my timing and tickling and plug woes, I had another run at the CR750 this afternoon. Same setup - petrol starter and lots of praying but this time with the knowledge of four good plug caps and standard B8EAs. She started with the usual back firing and half assed attempts and then with a tiny bit of throttle feathering - two consistent full four potted revs....and then she died again. We managed to repeat this three times only getting two good revs out of her before she went back to firing all over but man they sounded good!
I'm fairly convinced it's all *just* a problem of fuelling now. Pulling the plugs and three are a healthy shade of light coffee colour and No. 1 pot is black as a coal hole in Warrington.
All carbs are set up the same so not sure why #1 would be running rich but it's progress. I haven't a clue where to take it from here so may enlist professional help. Any thoughts though would be welcome.
So close, so darn close....
