Do you know what cfm the carby is? I used to get a crappy idle stalling flat spots etc due to it being too big. I sent it off and had it re sized to a 300cfm which helped but the car was never 100 percent right on gas so I got rid of it.
I remember seeing this for sale a while ago looks like a good thing. Would definatly go to Simon for tune/a series advice if you need to know anything on how to set up the gas research carbs let me know. I ran one on my car for 5 years with good results but decided to go back to petrol (e85) for ease of tuning and reliability.
I dont think il be bringing the y as I havent touched it since the nats and still have a few things to fix and no time to do it lately. Il see if Joel wants to put his 1600 on for a run Simon
