I also check the compression and adjusted the valves.......[email protected] wrote:I live at sea level....but here is my days work ...I removed the new weber and found trash in the screen so obviously I took apart the carb and cleaned it..clean the lines. Once I got it back together and started it..the idle was smooth but still stumbled or bogged when throttle was pressed significantly. So..though there is a new fuel pump and it checked out in PSI range..It still sounded as if starving for fuel. I added a second inline pump (the old one) and for the first time I had power in 1st gear and most of second w/o stumbling but it remains the same in higher gear. Any thoughts? Maybe I need more fuel pressure(a high performance pump)or is there any issues with the 720 tanks that may cause instability in maintaining fuel pressure?
this is exactly what mine does, i just got it last week like this. seems like others have the same problem. where should i start, i dont want to just throw parts at this thingjwrattlesnake wrote:Mine has just started doing about the same thing....cant figure it out....acts lkike its running on 3 cyl.....no power at all...so if you find out what it is post it so we can learn from it....there are a few others with the same problem....thanks
just a side note, you may want to put a pressure regulator on the return hose since there is nothing to keep the pressure up its just a loop. My truck was doing the same thing when i got it and the first thing i did was put a reg. on the return line problem solved.[email protected] wrote:well I solved the problem...as I stated a new weber was installed early in the process but turns out the jetting was way off from factory. I gradually stepped up the jetting (primary began w/130 and performs as it should on a 147. I hope this helps some of you guys and thanks for all the help!!!!!!!!!!!!!!!!
