  2. Thanks, I cleaned it a couple days ago with purple power and the leak looks like it is directly under the timing cover but low enough to be the head gasket. You think it might be the timing cover? Does that cover have a gasket? I'll check the torque in my manual and tighten them up to factory specs. Any ideas on the sizing/performance of the head gasket if it goes in that direction?
  3. I have a small oil leak from the front of my head. I'm going to assume it is head gasket as this is an original no-mod engine. My question is will my engine benefit from a thicker head gasket with the stock components? I plan on also purchasing arp head studs with this project. I have seen TOMEI gaskets from 1 to 1.5mm, Nissmo at .6 and Kameari from 1 to 2mm. Please chime in with your thoughts.
  4. If I could get it here to GA for $975, it'd be mine.
  5. Thanks! and I was wrong. It's the balance tube I was looking for not the fuel rail.
  6. Anybody know the company that trims all the unnecessary holes and brackets from the SU carb fuel rails? I found a site a while back that did a bang up job on the fuel rails but now I can't see to relocate them. I came across www.paltech1.com but I distinctly remember seeing some pictures of a finished/improved rail. Maybe someone on here knows what I'm talking about.
  7. I sure don't. I did notice that mine are a tad different (spokes go all the way out where yours have a small lip) Man I like your setup; looks sweet. I'll see if I can find the manufacturer on mine and post it later.
  8. Thank you both. That was very helpful. I found that most of my troubles were from a foam filter element that was sucked into the carbs. I've now put on K&N elements in chrome housings for both inlets. I'll post a picture later today. I think I was running a little lean on Friday so I adjusted the fine tunings a little more rich and seem to be running great now. I haven't pushed it to the red line yet. It's still idling a little high so I'll need to adjust it down a bit. I may be confused on the high-speed balance at 3-4K. If it is where i think it may be then the guy had lost a screw or something broke and it's now zip tied. Again I'll post pictures. I'm also going to hunt around for a good carb tuner here in GA that has a dyno I can put it on. Then I can watch an expert during the tuning process.
  9. I'd say it's popping but not sure. I've always had fuel injected cars. It is only happening when letting it decelerate in any gear (is that OK?). The spring you mention; is that the one on the bottom of the carb? That's the one I've been adjusting for mixture (has a pipe running through it with a hose connected). It's running as if it has a cam (don't know if it does though as I just bought it) I just drove it during lunch and before it was completely warmed up it stuck on me at about 3k RPMs for a good couple minutes. Then it went back to normal and ran out great for the 15 minutes of driving I did. I'm getting K&N filters for it today so I hope that will help out over the messed up foam elements that are on it now.
  10. Just got it! Camera pics: Clean with duckbill and BRE style air dam Original butterscotch vinyl and loop carpets! No cracks in dash.
  11. So I've been reading my butt off about tuning these bastards and it seems simple enough. I got the air balanced between the two carbs using the float tool thing but after it warms up a bit I'm idling at about 1100-1200. I set the mixture by raising the pistons one at a time and compensating each carb to make sure the engine did not die (almost dies but not quite). This was the second time (ever) I attempted to balance and set the mixture. I think they are balanced just fine (which was the easy part) but getting the mixture and idle right seems to be perplexing me. The first time I was definitely running it too rich (valves started to stick and I could smell gas). Now I think I may have set it too lean but don't know how to tell. Without getting an O2 sensor or a color tube can anyone give me suggestions on getting the mixture right? The books I've read don't describe how my engine is behaving after making the adjustments they recommend. For instance they say the engine will rev a little when I raise one of my pistons and then settle back down if i have the mixture correct. I've adjusted the mixture through it's entire range and never had that kind of response. I don't get any backfire from the carbs. The only backfire I've gotten is when i run it up and then let off the gas without shifting. I'd like that gone and maybe the two are related.
