Three questions :
1 - just rebuilt my 65 SB and it's Holley 4150. Running fine except for just after idle (clutch out @ around 1200 rpm) it goes lean on me - surges on/off hard until I gas it onto the mains (idles and runs on main jets fine). Very much like a plugged pilot jet on my motorcycle. Carb was cleaned thouroughly after full disassembly. Float level is right; stock jets. Thoughts ?
2 - Just had my A/C A6 compressor and dryer rebuilt. Before the compressor lost a seal the sytem worked fine and a mechanic told me that it was leak tight. A/C guys are now telling me that they don't want to just fill it up with oil and R134 because "the 1965 lines are not made for R134" and "when empty, the lines get all corroded and ....". Any problem with running R134 in a stock system (compressor is OK with R134) ? Lines were fine, but they did sit in an refridgerant-free, non-pressurized state for months with the compressor off. Could this have ruined the hoses and justify new hoses ? I'm tempted to fill the system and try it.
3 - If I were to chose to do a A/C system leak check I'm told they only pull about a 30 psia vacuum, and that this is not enough since the compressor puts out a lot more than this and so the check won't show all problems (then why the heck would anyone do a check like this?). Why can't I do a positive pressure of a higher pressure and do a similar leak-down test ? What pressure should be used (or not exceeded) ? Again, since it was leak tight before removing the compressor, I'm tempted to find someone who will just fill the thing (anyone know of a good A/C guy in So Cal ?)
Thanks for reading all this,
Mark
