1986 TMC 102A3 - Slow Take off

[Geoff]

If his problem is slow take off he needs to remove or back off the throttle delay, not set it to specs.  IF that is the problem.

[luvrbus]

My vote is remove it they are nothing but trouble when they get a little wear,and you need a different gauge for different injectors ,they are a PITA for no more good than they do 

[Templar52]

If i remember,you have to plug the oil feed on the throttle delay if you want to run without it. Or if you can jam the piston all the way inside. Oil will com out from the small orifice.

So the original reason for these things was for less smoke and better MPG?

Just less smoke on take off only when the turbo boost is up they are taken out of play by the boost pressure ,doesn't help any with fuel mileage I can tell.They are real pain on a steep grade to get the bus moving

We put one on the 4104 when we turbocharged it to cut the smoke on start out. It cut the smoke, but killed torque starting on a grade. Messed with it a lot till finally had it doing next to no delay. Especially bad in reverse with the high rear.

Yeah mine is hard to move around the yard especially for the first time. But I think that has to do with the brakes kinda stick from sitting between moves. I mean there are times where it will get up and go from a stop, but not nearly as often. Is there potentially a pre-emptive take off from a start that allows more torque?

Also, I'm in Florida so I don't have any hills, so I don't really know what it is like going up a hill. I don't really want to find out that it crawls uphill. I'd like to fix the issue before it becomes one

The driver can be just as effective at reducing smoke, with just a little practice in right ankle modulation.

A skill you can be proud of yourself with, at every pull away.

The motivation to get good at this quickly? Clouds of black smoke attract enforcement attention, and lose you friends in your neighbourhood.

Read again... enforcement attention... the best busnut is an invisible busnut.
Flamboyant carelessness doesn't do the hobby any good...

With the throttle delay removed, then, in those couple of moments when you want everything you've got, you can get as much power as it is capable of making, smoke be damned.

The hair raising fear moments are supposed to rapidly stop, as you get more experience.

happy coaching!

LOL without the throttle delay it makes it nice to smoke out the Richard head fruit inspectors in CA too

[sledhead]

and smoke out the toll booths ? oops sorry !

dave

[buswarrior]

Oh yeah, toll booths.

For the uninitiated, please idle slowly until the rear of the coach is ALL THE WAY CLEAR of that poor toll keeper...

Never you mind the following traffic, the toll keeper doesn't need that blast of exhaust.

That's showing some class, no matter what price point yer ride fits into.

Happy coaching!

Yep Low Class and right now we don't need any more smoke.

[jraynor]

You mean we're class A. Lol 

[Dave5Cs]

Nope

[luvrbus]

Yep Low Class and right now we don't need any more smoke.

I never smoked out a fruit fly checker but sure wanted to at Vidal Junction one time
