Hello, I am new to the Toyota scene. I just got an 85 4x4 pickup, with a 22r, mild cam, weber 38, port and polished head, about 5k miles on it.
The problem that I am having is that I am lossing power up the slightest incline. Checked the cam timing and it was off, fixed that, timed it and it got worse. Have been playing with the timing. I had it set at 0 with the lines plugged. The advance is working.
Does anyone have any help for me?
 
whats it have for a fuel pump?

what kindve incline hill on the hiway or offroad slow etc?

"fixed cam timing" was the dist off or was the actual cam/chain off?

I had the same problem on my 20r/22r with mild cam and 38 weber.
 
It has the stock fuel pump, and its working good.
For the hill, on road, and its got power in 3rd, but in 4th gear it has very low power.
Its fixed cam timing, and the advice I got for that was that it was a tooth off.
I dont have the emissions stuff on the engine anymore
 
the pump is working good or it has 5-7lbs of pressure?

mine ran good for almost a year then I put a gauge off the pump and found about 1-3lbs of pressure put an aftermarket stock pump on it and has 5-7lbs now and runs much better!

if you fixed the cam timing make the sure the dist. is set-up correctly these will also run with that off a little and usually hills need advance and your advance may be working but if the dist is off it wont work as well as it should.

is the cap and rotor clean? also Ive had older dist on toyotas wear out the bushing make sure the shaft the rotor is on is snug and doesnt have any play

--if those dont fix it (they should) off-road hills I had to adjust my float so all the gas wouldnt run out of it on steep hills...shouldnt be the case here but you never know

--what size tires this thing have? stock gears?



and welcome to MUD!
 
I checked it a few days ago and it had 5-6 psi
The cap, rotor, wires and plugs are all brand new, I think I got the dist in correctly.
I have to vaccum ports on the dist, only one holds a vaccum and from what I can find that is correct. I only have the advance one conected. The other one is for the HAC, and I dont have that anymore.
I was told that the timing advance at 2000 rpm should be about 32 degrees. I checked mine and its about 26 degrees. But when I check it at idle 900 rpms its 15 or so.
I tried to check it for pinging and I dont get any.
 
:meh:hmm...I dont know...might be something with the carb gummed or set screw off...

with 30" tires and a stock 22r you shouldnt have a problem

deeper problem sometimes messing with "port & polishing" can really change the HP range and Torque of an engine may have lost some top-end...thats if it seems like it runs fine otherwise...

or sometimes aftermarket cams needs adjusting gears so there set where they need to be...
 
I am leaning towards the adjustable cam gear. When it was a tooth off it had better power than now.
I am just stumped on this issue, and I cant seem to get it running right.
 
cheap fix: you tried advancing the dist 1-2 degrees?

I wana say mines @ 18* at idle
