you should be able to blow thru the TTV when it has power, after about 20sec, and you should not be able to blow thru it when cold.
you can just bypass the TTV for now if you have doubts.
mine went bad and I just bypassed it. it is nice to have as it makes the cold starts a little richer and can prevent some backfiring when first started.

Excellent! I´ll try this tonight. If TTV passes inspection I´m down to spark plugs. But I will be surprised if my plugs are causing the backfiring.
