Transmission or Engine ?

[jac04]

... since I need to remove plugs etc, I'll likely just wait til I drop it off...

I would check it beforehand. Asking the trans shop to check it is a little like asking the fox to guard the hen house IMO.

good point...

thanks for the help folks, I fly out in the morning but back Monday afternoon for my investigation - I'm sure we'll get it.

I also will check to see in full throw with pedal down - coming back to LaneRover and Gale's points, and now Jmrrr - I better double check.

appreciated, mike

The pedal is fully extending the throttle at the carb... so I can check that off.

One other thing I noticed, is the exhaust is also much thicker and pronounced than ever before - would that indicate something (other than perhaps they used different oils than before) ??

What do you mean by thicker? If you are seeing smoke here is the key:

Blue = burning oil
Black = mixture is too rich
Thick white and sweet smelling = burning coolant (head gasket, cracked head, cracked block etc)

A new set of points can really transform the power output especially if its been a while. Used to have a saab that needed them every 3000 miles or so for some reason...they were cheap and easy to do but made a big difference.

It appears actually thicker white with black mixed... I hadn't noticed smell to be sweet, but definitely a more notable smell.

With respect to the power, it seems to quickly die off when a load is applied - for example, revs fine when standing still, then as you try to pull away on an sort of incline at all, and it dies quickly almost to a stall. If the road is level this effect if less, but will never come close to reaching full speed it had in each gear... with 4th gear the worse in terms of having any pull or top end...

thx

This thing sounds like it just keeps getting worse!!!, look inside the valve cover after engine is warm, see if you have white frothy stuff, do the same with the dip stick then i'd say run it down to an independent and get this diagnosed before something big screws up.

Sounds like the engine has some issues. Look for the chocolate milkshake oil and do a compression test on all four cylinders.

I didn't get a chance to look inside the valve cover, but get this..
I just found the intake elbow to carb (from air filter) was also not secure at the carb, but rather sitting on top of the carb with c-clamp tight to elbow, but elbow actually resting on top of carb rather than securely tight over it. As it was sitting flush, I hadn't noticed it not actually clamped on to the top of the barb - not sure if alone can cause this behavior, or if it perhaps contributed to creating another problem. I had to run to the airport so didn't get a chance to ride it yet however.

Any thoughts on what specific behaviors/problems this would be causes by not having an air tight seal between the air cleaner elbow and the carburettor intake.

I can't wait to talk to that trans shop... I think my first question to them might be something like "Have you ever picked up your teeth with broken fingers" ?

If the intake boot is off the only issue you would have is the engine will breathe unfiltered air. I'd wonder if the boot slipped off on its own or if someone had it off and put it back on incorrectly. If the transmission shop had it off id wonder why.

Make sure the choke isn't stuck on.

Pull the plugs and post a close picture of them. This is sounding more like a mixture/ignition problem now. In the meantime do the usuals like check the timing and point gap.

Thanks, will check that as well when I get home late tomorrow. Thanks again for the help.

Definitely seems like a load from the dark exhaust...so agree mixture related - and for sure it "feels like the choke is on" from a behavior standpoint, but it is not pulled out on dash, and at the carb is as far back as it goes - could the choke mechanism inside the carb be somehow fault/stuck ? any experience there ?

Dropping off to have the Trans elements checked now...
I also have a new Distributor and points if needed.

What carb?

Have you checked to make sure the intake isn't obstructed? Sometimes the flexible air intake hose delaminates on the inside, blocking airflow to the engine above idle.
