[Gmecm] Tracker TBI Problems overcome!

[Ford, Pat]

Dizzy based, ecm controled, but they run well with just about any cam
timing.

Tracker, sidekick , pontiac sunrunner, asunna something, GM and szuki
did a joint venture and were very promicous.

these questions are kinda my point, steve put it well:

 I'm not sure the problem is completely solved yet so I'm still curious.

so, having one to compare would be a great start, and IIRC isn't the
tracker a Suzuki in disguise in that vintage, for those not knowing the
engine well?

If it's a dizzy based, and the timing pickup were off a crank sensor
somehow, that would wreak havoc to no end if the sensor is reading flux
off the damper and it slipped. not only timing but relation to rotor
position would be affected also, but sounds like if you can adjust
timing it is a dizzy pickup, so unless something is wierd in the dizzy
then possibly the indicators are broken and functionally if you add the
proper offset for the bad timing indicator that explains it.

Bottom line, if it's a mechanical issue in the timing reference to the
ignition and broken, then the problem will return and probably sooner
than you desire.

good luck, interesting thread, and appreciate hte continued feedback!

I don't know TBI models but how are they timed ?.

Are the hubs fixed with a key like Gen1 Chevy motors or just bolted on
like the Gen2's appear to be?

Could the hub have slipped or the rubber part between the hub/damper ?

Thoughts anyone !
