Hey guys, most of you have been following the saga of my 69 RR. Runs for a day, then back on the tow truck. OK, so I wanted to throw out there what exactly is happening and a short timeline of what has been done to the engine, etc. so maybe it will ring a few bells.
Dropped her off to a "mopar guy" for carb tune, 1" carb spacer, fuel leak fix, kill switch installed. Once he got the carb adjusted and the spacer installed, she ran the best she ever has. I drove her home over 40 miles without incident. Parked car in my garage for a week; started up on a Sunday morning perfectly and drove about 5 miles or so, then she bogged down and gave out. This is when the problem started, out of nowhere. Towed back to the shop. He found debris in the carb that was jamming up the fuel, ran great. Apparently he took only for a short test drive because my buddy Jim ran up there to pick it up last week and he got about 5 miles and same thing happened to him, just gave out.
When it cools down, she runs fine, then once she's up to temp, she dies.
As I am typing this, the guy at the shop just called me and told me what he found, but he isn't sure WHY it's happening. Here goes. . .
He starts her and it runs perfectly. Let her get up to 200 degrees, took off air cleaner to see carb, get engine up to 2 to 3,000 RPM, and he's telling me that he can see bubbles in the front sight glass on the Pro Systems carb. Carb is not hot, but he says the fuel line from the block to the carb is hot. Says this is where those lines run out of the factory so he doesn't understand why the gas has bubbles in it.
Once she cools down, fine again, then same drill.
Anybody have any clue as to what the bubbles in the front signt could be? Why would the gas be getting that hot? Maybe it's not boiling, but air in the gas? I don't know. He said he'll look further into it this week, but wanted to throw it out to you guys.
The strangest thing is that it ran 40 miles at 3500 RPM perfectly just before this started happening.
Any thoughts guys?
Thanks, John.
