I will post my answer to yesterdays accusations of being, a troll, a raciest, not here to help and to ignore me, #120, here today
This is a "Tech" thread and the answers will be used for solving problems. If someone posts an incorrect statement that will/could lead to ongoing problems for someone looking for help, and i see it and know it to be misleading/wrong, i will correct or dispute the information.
If there is a difference of opinion then i would advise anyone reading the dispute to do some research though the Google search, above left, or through members handles for posts and threads created. This will help determine the experience of the member. Post counts count for nothing
I know enough about carbs to suggest that a trumpet player who hasn't hit a bad note in.............. 10 years.............. may..........and i stress...........MAY........... be able detect a slight variation in wind velocity when bench sync-ing carbs by putting the throat of the carb into your mouth and blowing.
An easier and accurate way is to ensure each butterfly is centered and seated properly with a visual check against a background light.
Place a piece of paper, same thickness, under each closed butterfly. Using the throttle lever the paper should be able to slide out as soon as there is any pressure applied to the throttle. Do the same with the other carb. For linked carbs this process can be done when the carbs are separated but the adjustment screw will have to be backed off before the carbs are linked again.
If this is done when the carbs are linked, back off the sync/throttle adjustment screw, and do the left carb first. Tighten the screw till it beds without opening the butterfly, again use the paper to check that the butterflies open together and the paper slides out at he same time.
The other 2 accusations i do not need to address
