We had a plumbing error and were not getting fuel. In the process of replumbing, the pump fell and broke. The car is running on gas from a squirt bottle

Sounds Good. Sorry about the pump! Maybe you need a good hands man like me.

Plans are to work on the TR7 this weekend and bring it back to WV on Sunday. Then I can take it to a local muffler shop here and get exhaust put on it. Jim says it runs, so we need to do a little tuning. Also the HTOB needs a seal kit, so the tranny will have to come out this weekend.

Dan, do you think we're going to see it running at the meet? 😊

Scott, I plan to have it ready by June. I am bringing it home from Jim's on Sunday, so I will have it here, so unless I break something between now and then it should be good to go.

That's an excellent video clip Dan. But then I guess it would be considering whodunnit. So... pipes and mufflers, and there's little doubt it'll be at the meet in Lewisburg. OK, I'm envious....

One of the tricks we needed was a pedal stop for the clutch. When fully depressed the clutch re-engaged and would not allow Dan to shift it into gear. But a test drive showed that it would fully disengage halfway down. We welded a fabricated nut plate to the back of the clutch arm (done in the car) and added a 3/8" carriage bolt and lock nut to stop the pedal halfway down and all was good.

We also found a new failure mode for the HTOB. (Which was in fact just fine. We did install the new seals anyway.) Because the feed line had not been pulled all the way out of the bellhousing it had a loop and got up against the pressure plate. So once the engine had been started it stripped the braided sheath and holed the liner. Found a stray hose in spares and fixed that easily enough.

What Dan's video doesn't show, is that this car is going to be FUN! Dan, Carl and I all drove it down the driveway and back. We all got silly with it. I'll be sweeping gravel off my driveway for a week! Dan sat on the hill and tried to use up his aged, hard, and way too small rear tires all in one go. Luckily the rubber was so old that it mostly left powder which the rain has washed away but there's still a mark that will be there for awhile.

The initial tune was surprisingly close and he can drive it like that with no problem. There is a little work to do to enable the radiator fan control and get the IAC going, and the warmup is too rich, but he should have no problem driving it down to the muffler shop. After that? Well Dan, just watch that right foot until you get some real tires under it.

Jim

Just wanted to say that this project was a blast to be a small part of & to watch Jim work his magic.

Now Dan's TR7/8 has a proper engine!
