I asked as the installation instructions call for a b7es, which I always thought was too hot.

Picked it up today. Came with a load of body pieces off a jet200. It's in pretty good shape considering it was last on the road in '79.

The blue one had been sitting for last 20 yrs in a garage. There was rattle can respray at some point so I'll elbow grease that off. Crack in the headset, looks from transporting with hand grip tie downs, but otherwise it's complete and not seized. About 5,000 miles on the clock I'm picking it up th...

I'm running a stock crank and bgm clubman with my GT200 kit. I've heard before B7ES but that seams hot to me.

Curious what others run

Sorted. The choke jet (60) is too lean. If I wound out the mix screw past 4 times it would almost catch. So I went with a 50-120 idle jet. Fat but doesn't impact the main jet much. I have mix screw turned out 3 times. Starts first kick on cold. It's raining too hard to check the rest of the throttle...

Cleaned carb and jets. Choke jet is a 60. Issue still there. I swapped out the carb with a 24/24, standard jets, 128 main. Same cold start issue but otherwise ran fine. The choke lever works as it should. I'm going to double check the timing (should be 19). It's got a new bgm stator, spark is strong...

I tapped the dummy centre plug on my GT kit for the red ring heat sensor. It's reading is below actual, but I'm okay with that. I just concerned with differential. I've got a feel now for max normal running temp and periodically check to see it's in this range. I've experimented by trying hotter plu...

Jets were clear but there was what looked like very fine hairs under the filter, and there was a few particles on the needle that was probably preventing needle to seat closed.

And to start it only needs a small amount of choke compared to stock.

Mines rich at the bottom end with a stock 55/160 pilot in when using a big main, thinking of going leaner on the pilot, i could maybe then go up on the main to a 135 because I could do with more plug colour higher up, I,v noticed when looking into the carb that the main comes in as soon as the slid...
