Re: Throttle Body vs Carb Spacer

Thanks for your reply.

Sounds like a carb spacer would be pointless for my goal. I don't seem to have any intake issues, the engine runs exceptionally well and while we've only had it during cold weather, the climate here in the Sound is mild (if the heat difference could cause boiling in less mild climates).

What's your initial timing?
I'll be honest in saying I don't know exactly what you're saying.
When you ask for the initial timing, do you mean what's listed as a spec in the service manual or do you want to know the current timing as read with a timing gun?

I'm mechanically inclined and have never had issues doing anything in terms of replacing/maintaining parts. Getting into tuning is something new to me, but I learned everything else, so time to start doing some research. Overall, sounds like I'm a bit ahead of myself trying to do things like change parts without making sure its tuned well first.
