[DML] Re: Fuel Enrichment Circuit

["DMC Joe" <DMCJOE@xxxx>]

David,
Close your wallet, no need spending that kind of money.

Here are a couple of questions.
Are all vacuum lines properly connected ?
Has the CO mix ever been adjusted ?
Is the tamper proof plug still in place ? 
Do you hear the frequency valve buzzing while the engine is idling ?

BTW both the warm up regulator and frequency valve have an extremely low
failure rate, I seriously doubt that either one needs to be replaced.
