More before and after pics:
Thanks man. Yep, exactly. Also had a water bottle to spray it all down and then hit with the shop vac. I did this maybe 3 times. I still need to steam clean it. Definitely some visible spots there in different lighting.Tentin said:The before and after on that seat is impressive. You just used purple power and a brush?
Yep, this cluster seems to have come off of a 3.2. I rolled the dice on it after I found this post which describes an adjustment pot inside the casing. I received and cleaned up the cluster yesterday and will be removing casing to locate the potentiometer in question and drill an access hole tonight. Actually calibrating will require tools that I don't have.DSUZU said:While that cluster looks like it MIGHT be right (and I HOPE it is), a Rodeo cluster should not be correct. Rodeos (1991-1994) did not come with a tachometer on the 4 cylinder models (to my knowledge). A v-6 cluster tach will not read correctly. Dennis
Happy to! It's a '73 Fox Thunderbolt. Back then they called it a "minicycle" - cross between a minibike and dirtbike. We upgraded it with Harbor Freight Predator engine (the Honda clone) and knockoff swingarm from Honda monkey bike. Also has a knockoff comet torque converter. The pickup is currently taking it's parking spot (and a bunch of other crap) in the garage so the bed is getting filled up.DSUZU said:Okay, we now need to go down a rabbit trail on this thread. What kind of bike is that in the back? Looks like maybe a regular cycle with a "mower type" engine fitted to it? Gotta know. Dennis
Actually the harmonic balancer on these is a well know failure point.andy_sykes said:Iunlikely unless it was at a point of failure already, or unless you ran it a really long time with a misfire) it's unlikely it will be damaged.
Thanks and I appreciate the links! Looking at the condition of the two cats it for sure looks like some kind of band-aid junkyard fix to add the 2nd. The rattle is extremely annoying so I'll be looking at it soon.andy_sykes said:It's cool seeing your progress! Keep posting!
About your squealing, my guess is it was related to the fuel dumped into the engine bay. It might have got thrown on your belts and caused them to squeal.
As for the balancer, unless it was damaged due to the misfire (unlikely unless it was at a point of failure already, or unless you ran it a really long time with a misfire) it's unlikely it will be damaged.
That picture of the exhaust system seems interesting. It could be modified, but the weld doesn't look super terrible.
I was curious so I found a couple answers on some different websites.

So, either Isuzu was trying to push more power and it was cheaper to add a secondary cat, or some previous owner might have had trouble getting it to pass emissions and just decided a junk-yard cat would help.
I'm curious to see what you find, as it seems the trend to add an additional cat is relatively new.
Ah was not aware. Added to the "shopping list." Thanks!mudoilngears said:Actually the harmonic balancer on these is a well know failure point.
