tuning carbs
 

Anyone in south jersey or close to south jersey good with tuning demon carbs? thanks

Maybe you should put it in the south jersey one?? might get more hits that can help :scratch:

Umm. Myb it has a lil to do with Engine work. So best bet is in here.

Anyway. My buddy has a demon carb on his 68' Vert but he lives in Lodi. If it was a Q-jet i could help u out.

demons tune the same as holleys pretty much, just more forgiving if you aren't dead on. pretty straight forward, if your eyes water when you stand behind the car take a few jet sizes out, if it pops through the carb go up a few jet sizes. lol
hit me up on AIM to talk about it in more detail

be extremely careful cause my Demon would never tune right, we decided to take it apart to check the jet sizes and three of them were the correct sizes but one was a 90 or something rediculous like that. This was on my Speed Demon 650. we swapped the jet back to the correct size and away it went and I have not looked back. Once ya get them right they are awesome. However getting them there is a major PITA.

PM me your # and maybe one day after work this week I can stop by and give you a hand...

#96 to be exact in Jon's carb.

In my experience Demons are Extremely finiky to the settings. Where a Holley is forgiving.

A slight rich idle mixute setting for street driving in the summer will be dead lean and tough starting in the winter.

Another problem i've had with demons is they will cause the motor to break up under load if they are a few jet sizes lean from Perfect. I've never had a Holley do that from a few Jet sizes.
