so whats the stock setting for a 22R?

5* timing @ no more than 950 rpm with vacuum lines plugged..... also says cold idle should be 2600 rpm

[79coyotefrg]

8*

[THK Matt [OP]]

8* is stock, so 11* is better right?


also where is the best source for tuning the stock carb for the best economy and performance...

[79coyotefrg]

Marlin would be the best  person to ask THAT

Sounds right to me (unless it starts to ping)

cant find how to tune a stock carb....

does he have an email?

[jimbo74]

does he have an email?

you can PM him just like everyone else, he is a member on the board.....

that is what my sticker under the hood says

[79coyotefrg]

cold idle is 2600 rpm 

[THK Matt [OP]]

i didnt know he checked them

that is what my sticker under the hood says

okay wasnt sure if thats what you meant, my bad.

cold idle is 2600 rpm 

that seems way to high.

[emsvitil]

Remember that when you adjust the cold/fast idle speed, the engine is warmed up.........

When cold it won't be that high.

yup, it does say that too

supposed to set the idle and cold fast speed @ normal operating temperature.... haha, i guess when its cold, it does its own thing, lol

[jimbo74]

Hot engine operations.... Adjusting your valves

thanks Jim, that helps alot

[jimbo74]

thanks Jim, that helps alot

i know... im just a pimp like that

[jimbo74]

here is some good info i found in searching for my issue about a missing carb bolt.... i kinda don't agree with the way to set the cold idle though, his writeup says do it cold, but the FSM clearly states to do it @ operating temperature.... maybe i just interpreted it wrong....

So factory timing is 8* at idle (under 900rpm). I always thought it was suppose to be 0* at idle because its an interference motor.

[blackdiamond]

its an interference motor.

22RE? 

[H8Mud]

i was under the impression the 22r is an interference motor.

[emsvitil]

It is, but that has nothing to do with ignition timing.........

[KDXSR5]

Correct, the interference part comes into play when you screw up on your mechanical timing AKA the timing chain. If you screw that up, you screw up your engine. Ignition timing has nothing to do with it, as stated above. Ignition timing is for IGNITION or in other words, when the spark is delivered to the cylinder.

yes!

see you time the crank and cam shaft at 0* and then you retard it 3-8* BTDC with the distributer.

[H8Mud]

yes!

see you time the crank and cam shaft at 0* and then you retard it 3-8* BTDC with the distributer.

so timing should be retarded 3-8 degrees or advanced 3-8 degrees? I have a 22r and run it at 0* at an idle of 700rpm with the vaccume advance plugged.  Should i advance it until it pings and then back off a little to obtain the most power? or do these motors run better slightly retarded?  I seem to have decent power now and just passed cali smog with no problems.  I also just rebuilt the top end with new head and rolled in new bearings on the main so i know the motor is sound.  I havent advanced it because my motor runs kind of warm as is.  Im running a v6 3 core radiator and the toyota dual stage 190* thermostat. I also have a brand new fan clutch and water pump, i run about 190-195* around town and about 200-210* on the freeway at 70mph at 3k RPM.  I have 35's and 4.88s.

[THK Matt [OP]]

well stock is 5* BTDC which is retarded IIRC, so retard it 3* more for a total of 8* BTDC. that should be perfect.
if it pings.... back it off a bit.

[emsvitil]

BTDC is  BEFORE Top Dead Center   which is

ADVANCED

not retarded

[THK Matt [OP]]

i stand corrected, thank you emsvitil

(EDIT)

well stock is 5* BTDC which is advanded, so advance it 3* more for a total of 8* BTDC. that should be perfect.

only one retarded here is you 

BTDC  is ADVANCED


cam timing is NEVER set to anything besides 0

[H8Mud]

thanks guys! What engine temps do most of you see with your 22r motors?  Im not looking for "my factory gauge reads half way"  Real temps from after market gauges, cause we all know how well toyota gauges work 

[jimbo74]

the toyota temp gauge is actually pretty accurate beleive it or not, when it isnt plugged up or if there arent otehr issues in the system.....
