what to do 1st

[alke46]

I saw this thread posted yesterday but today I can't seem to locate it.

Question was asked whether to synch the carbs 1st or set the air/fuel mixtures after dipping and reinstalling carbs.
Which job should be done first?

Thanks,
Larry

Set the mixture screws to 2.5 turns and then sycn. Fine tuning on the mixture screws won't mess up your sync.

Clean carbs.

Bench sync them as per factory manual.

Set mix screws to the recomended amount of turns out for your model.

Vacuum sync them

Then adjust fuel mixture with a colortune or best idle method.

Do plug chops to verify. You may have to change jet sizes to get the mix right.

Hope this helps.

Thanks to both Nessism and GQROD for your input.
I shall fire up the old girl today.

Perhaps you've already done this...

Hi,

Don't forget to make sure the proper valve clearances are set before you synchronize the carbs.


Thank you for your indulgence,

Yes this is the most important thing youi can do or you will go nuts ( like i did, till basscliff saved me with a tip on making my own valve adjuster tool with a deck screw and wooden dowel-thanks again for that one! ) trying to tune it.

yes, I did the valve adjustments 1st. Thanks.
