Stop in for a cup of coffee

that's not running rich - that's fuel escaping before it goes into the cylinders.

So what should I be looking for in this instance?

As far as opinions, I thought TMM's meme yesterday pretty much summed it up.
:lol:

Of course you have no easy way to judge if anything I say is experience based on facts.

I have a very high confidence level of the information I receive in here. Доверяй, но проверяй, "Trust but verify" as they say....

Changing the main jets is mostly to change the high speed cruise.

So I should stick with what is in there and assess from there is what I'm gathering here. Perhaps other areas of the system are to be considered...timing etc. (??)
