My newly obtained 1985 ITC Honda Civic has a problem .

Symptoms ,
Starts hard and pops untill warmed up . Then idles ok .
Won't rev past 6000 RPM and won't rev past 3500 without popping and backfiring .
Stalls and won't start up again .
Fuel pressure gauge says there is between 6 and 7 psi after fuel pressure regulator .
Fuel level window shows on carb shows good .
I'll be checking fuel filter for blockage , but has fuel pressure .

Specifics ,
Honda carb ,
Stock Honda ignition ,
Not familiar with either ,

"I" don't think this is a fuel issue but like I said I'm no carb expert .
I hate to sound like a dummy , but I know there some experts out there that may give me an avenue to pursue that I haven't thought of yet .

I am planning on converting the car over to LP GP for next season but just in case I don't I'd like to be able to figure it out .

Thanks .
