Increase main jet from 110 to 115 or 120?

  Tip cleaners (for jets?)

dcarver220b publicación=33855 id de usuario=250Estoy usando un escape DG-6 en 1 con colectores CermaChrome y filtro K&N. La elevación es de 0 pies a 1200 pies la mayor parte del tiempo, a unos 800 pies.

Tengo que revisar cuatro cremalleras más; una vez que estén listas, será fácil cambiarlas y probarlas en mi ruta de prueba. 

Ah, usé un ColorTune o como se llame para ajustar la mezcla de ralentí. Excepto el carburador 1, que sigue sin responder a los ajustes del circuito de ralentí. 

Maybe what I'm suggesting is silly...

Have you tried driving with the starter lever at 25% of its position to enrich the fuel mixture?

Just for the test.

As am I.

From experience:  If a pilot needle is not showing a response; in my case it was because someone had used one of those damned "Jet Cleaners" and damaged (over-sized the pilot needle port in the venturi. 
I was able to repair this but it was very "tricky" and frankly - I think it was more luck then determination.
 

This is worse than that. Recall I sent a rack to a so-called pro which can back w very bad results, one of which the idle seat and jet had been replaced with god knows what.. threads different, jet length shorter, and bent too. But, even in that 'fixed' position, the mixture was close to optimal... so sigh on the bad work, but good enough to run adequately... not perfect,, but ok.

I have 3 more carb racks headed my way, so I'll have a total of 5 of these things. Between all of them, hope to make one 'perfect' rack. Cause us guys like nice racks!
