new owner '74 TCS misc ?

[Lumbes]

Still waiting on the gaskets from rdent.  They shipped them out immediately but UPS keeps running into adverse weather so relocating it to a UPS store for pick up.

Nearly ready to turn the engine over for a test.  Have a question on a vacuum line or something. It was connected to the down draft webers that were on the car and ran down towards the bottom end of the engine attaching to some top looking like part.  Should

I be connecting that line to the Mikunis?

Your dizzy has a vacuum advance or retard mechanism so you hook the hose from the “top looking like part” to a vacuum source (i.e. intake manifold).

Thank you for the reply.  Found a vacuum on the Mikunis and attached it to that.  It is the line looping and connecting by the top of the carb closest to the front of the car.

I don't know how it will run but aside from the taped on throttle mount it is looking nice.  Working on a solution for that but that's where I'm at pre start.  Secondary intake manifold fits nice upside down so will see how it works as a high balance pipe now.

Any reason you are running the throttle cable on top and not through the throttle cable hole that is already built in the manifold?

Make sure the "purge" fitting is plugged.  No TC came with a vacuum advance unit, they were all vacuum retard for emissions.  Remove the hose and plug the fitting on both carbs.

Hook the engine breather to one of the air filters.  You can drill a hole in the side closest to the inner fender.  As long as you engine is not worn out and smoky, it will run better that way (slight vacuum in the crankcase).

I turned the intake manifold upside being it was a federal low balance pipe type.  Didn't want that collecting fuel.  All the other passage ways were sealed off along with the top with a plate.  Turning it upside down changes the angle of the hole.  Still could be used if i

redrill the hole though.   Might be as simple as that.

Was looking of reducing the breather tube length I have.  It used to wrap the whole way around to the carb further away on the webers.  I'm considering in going  in with the closer air cleaner for that route.

Thank you jbcollier for the clarification on that vacuum line for the emissions coming from the engine.  Wasn't sure what to do with it.  I'll remove that and plug both fittings on the carbs.  Both "purge" fittings are plugged.  Engine runs pretty clean so that should be

a option for me.

I'm calling it a night though.  Pretty tired and didn't even realize I already started repeating myself.  Ha oh man I'll try again tomorrow.   thank you for all the help everyone.

The secondary manifold looks way better upside-down, functions better as well.  I agree a more aesthetically pleasing method of securing the throttle cable would be nice.  It's early testing days though.  That can be changed later.

Started the engine last night.  Without even adjusting the carbs from how they were sent they brought the engine to life once fuel got to them.  Took a couple key cranks but nothing excessive.  I then set the idle which wasn't far off and adjusted the

accelerator pumps to eliminate the delay when getting on the gas pedal from an idle.  Used a carb sync and it is looking nice and even.  Engine is running smooth and is responsive.  It sounds like a great improvement compared to the downdraft weber

setup that was on it.  Won't know the whole story until I get it on the road but with how it is responding in the garage I can assume it is going to be great.

Looking forward to your road test review!!

[jbcollier]

Excellent news!

[Bainford]

Great to hear! Looking forward to a road test report.

[Lumbes]

With weather at the low 50's today and relatively dry roads I was able to put the new carbs to the test and couldn't be happier with the results. 

The difference in the drivability is night and day and the engine now surges into power at any point in the rev range with zero hesitation.  It is quite fantastic and i wore a grin on my face for the entirety of the drive.

I have no issues or complaints with the Mikunis so far.  They were incredibly easy to install, tune and the engine now has the agility to match the rest of the car.   

This community is awesome and thanks to all for the help.   I
