Re: Vacuum signal

Good that you're putting the secondary metering block in - just so much easier to tune. I would start with 68's. Does the new metering block have a power valve or not? (I can't remember?). If so,...

Re: Vacuum signal

I think your primaries are fine - in that you were in the 12 to 13.5 range. The only part that I don't like is that when you were under full throttle, that you were are 14.4 with boost (did you stay...

Re: Vacuum signal

Great news! Sounds like you found the big source of it going lean and stumbling as a result. I'm with Ron - once you get a little more seat time in it, you might advance it about 2 degrees at a...

Re: Vacuum signal

You cannot trust the AFR meter if you don't have a correctly installed and sealed O2 sensor in the exhaust system. It should be at least 18" back from the third (rear) exhaust port, should be...

Re: Vacuum signal

Hey - why not put some additional tuning into the 600 and see if you can make it work - definitely worth a try (you already have the carb). If that doesn't work and you still have the same problem,...

Re: Vacuum signal

Okay - might as well jump in again . . . this is a regular "tuning party"! LOL

1) Reading Plugs: You can't run the engine under load, take your foot off the gas, idle around a bit and then look...

Re: Vacuum signal

I agree with Ron on the timing - it is coming in too early. I'd aim for a total of about 16 - 18 for now, but have the mechanical portion of it start at about 1000 or so and be all in at about 2000...

Truth be told, nobody can tell you how much advance your combination needs - given that I'll...
