Anyone have a manual for a 'k' motor they could tell me the points gap? I can't seem to find it on the net.. and unsure if its the same as a 3k or 4k..

 

 

3K is 16 - 20 thou (0.4 - 0.5mm)

 

Dwell 50 - 54 degrees

 

Ign timing: 3K 8 degrees, 3K-C 5 degrees 3K-B 10 degrees

 

3K 600rpm, 3K-B 650rpm, 3K-C 750rpm 3K automatic 700rpm

 

 

I don't have anything for one of those modern 4K's.........

Those numbers are pretty much the same as 4Ks, off the top of my head 4K is 8 degrees and points are 0.45.

the 1100 K-C motor is 0.4-0.5mm point gap...0.8mm plug gap.....5* ATDC @650 rpm....intake valve 0.08mm, exhaust valve 0.18mm...from the 1968 owners manual.

cheers guys!

If you have a dwell meter it is more accurate than using feeler gauges. Once the points have a pit on one side and a lump on the other then feeler gauges measure it wrong every time. Even new it is easy to not get that gap perfect.

 

5deg is nothing! Do they respond well to more advance? 8-10deg on 95 octane??

Yeah my 3K runs way better with more advance...I think it helps with the crappy ethanol gas we get now and I usually run the cheaper 87 octane...but he had asked for a K manual and that's the factory settings. Back then you got nice leaded gasoline...actually ran a bit quieter..and you could tell if the engine was running well from the chalky white tail pipe...if it was black in there like they all are now , something was wrong.

 

My original 1100 K ran best at about 8deg or so....set it all up to factory and then just twist the dizzy till it pepped up a bit.....and it was OK with me taking it to 6600 rpms on a regular basis for about 300,000 miles after it's first freshen up at 250,000. (just fresh rings and bearings, no honing or turning whatsoever, no new lifters, pumps or anything)

 

When the original Toyota factory parts started to go bad (they lasted 21 years by the way) and I had to start getting aftermarket water pumps and alternators and stuff...well now it's a yearly round....hey , starters out... time to start shopping for a water pump...then alternator...voltage reg....bulbs(just replaced all the original interior bulbs that lasted over 40 years and still worked but were getting dim)...shocks....once you get it all replaced , start shopping again.

yea dwell angle is the way to go. 4k : 52+- 6 deg but if using feelergauge,

toyota K manual suggests to adjust to 0.45mm rubbing block gap.

 

That way pittings and lumps on points doesnt affect the measurement.

Renew if bad tho
