Hi! I have had a frustrating year of working on my new old suby. I bought it for $300 from a friend who is a terrible girl driver...typical. She tried to drive it like a race car...I had a new Weber carb put in it because it would not hold idle but runs amazing. After the new carb I took it to Moab and it started popping and ticking under hood or backfiring out of carb. (I have had a mechanic look at exhaust manifold for leaks, nothing.) I also had them test fuel pump because I changed the filter in Moab and it workd 100% better for bout and hour. There is also a gurgling noise coming from heater core, I am told this is a leak and air is getting into the system. It runs great up to speed but doesnt have much power getting there and idle is all over the place. sometimes its great, sometimes it suks! If any one has any advise for me please let me know. I want this car to be more than a grocery getter. And I need to go climbing soon Thanks!
