Day 2 start up.

[Kim K Kaiser]

Adjusted timing bck towards advance, ran much smoother.  Only a couple initial pops out of carb.  Replaced carb gasket w felpros, no sign of leak there.

Got about 30 min of runing at 1250 to 1500 rpm.  Oil pressure was good,  32 to 34 initially. Down to bout 28 at shut off.  Engine a little hot at end almost half way.

Some popping noises inside.  Like internal backfires.  Not metal, but there all the same.  And frequency increased as i approached 1500 tp 1600 rpm.

One thing at back of valley pan that worries me,   note color of fluid.  Id that oil n antifreeze?   Normal during breakin, or are my head gaskets not holding?

I will ck a couple videos to utube, see if that thumping is visible and any other things anyone may see or hear.

Timing at 1500 was about 5 to 7.  Seemed smoother there

Probly chg oil tomoro,  its milky.  B4 running again

[Jason Edge]

Kim, congrats on the start up. The engine seems to be running smoothly. Normally you woudl change oil at 500 miles (or at least by 1000 miles) but since oil is milky you would want to change and monitor closely. This may be due to various leaks, but otherwise the oil should remain quite clean until you do that 1st oil change. Let us know if oil stays clear after change.  If it is getting milky again it cut point to leaking or bad head gasket seal, etc. Hopefully, it is just one of the prior leaks you have addressed. Good luck.

[Kim K Kaiser]

Thanks Jason.

I reran it again, chged oil, filter, etc.  Pulled valve covers gave everythingva retighten,  i may hv actually missed one or two that i had tightened down to abput 50 in my sequencing tightening and missed on the final pull, but evertything is tight now to 75.

Ran about 20 min at 1500 rpm.  Was cking for that murkey leaky and itnever materialized,  oil was clear as bell after run on stick, were it it had been murkey before the oil chg.  So maybe that tightening up did it.  Hope so.

Engine runninf a little hot, like a tiny bit before midway, about the gauge needle.   When it shut off whem i tried to decelerate to set timing  when i started it back up, it was way over the middle. Almost 75%, so. Not sure what that could be, but it backed up some once i got it running

I kind of dnt think mt distributor is in right.  Car idles at 900.  If i try to push off the acceleratorvat the carb,  car wants to die.  So i cnt get it to 450, 80 to set timing at idle.

Anyway,  attaching a last video, still getting some backfires. One every other minute or so, and that sort of deep engine kind of backfire,  videp isnt picking that up.

Nvr got reslly low enough to test at 480.  Tried to keepit upfor breakin

[Kim K Kaiser]

Read my reply tp Jason above,  spells out todays running

[Kim K Kaiser]

Yes, i out white out ib the markee

[Kim K Kaiser]

I tried to go CW but engine wont hold up to run at 450/480.  Gonna hv to put on hold for a bit

I am currently putting the car on my trailer and beginning long journey back to montana for summer and tge busy tourist season.  Takes me about four grueling driving days to get thrre from MS.  I will try to get back on it when i get back settled up there.

I had always hooed from beginning to hv it running by this time,  but as tgey say, best laid plans of mice and mem.

Thanks to everyone who has had thoughts and comments on my adventure into this rebuild,  coukdnt have gotten to this point without everyones help.and thoughts

Been a while since i cked in. Got bk to montana w car in tow. Had some offline instrction on rochester, tuning etc in the meantime.  

Backfiring was from hving 2 & 4 spark wires crossed.  

My bent tv rod was preventing the accel from going all the way back, so got idle back to 500 w timing at 7 to 8.   

Had some instrction by using both vacuum gauge and rpm tp try and set carb.   Not sure were it stands right now.   

Engine runs half way between 1/4 andv1/2 temp while sitting at idle.   

I took for short ride today.  Thought i had trans prob for first 50 yards. But remebered fluid was out so put 5 quart in.   Took about 4 loops around block.  Some adjustment gonna be needed at tv rod i think.  But engine seemed to feel a bit more strong.  

Temp is worrysome though, it was a full 1/2 for the short ride.  Going to put infered on it at the temp sensor, see what that says, isvthat a good place to point it for this measurement?
