1950 Dodge Wayfarer cylinder numbering

[Bill Stephens]

What is the 6 cylinder numbering?  Number 1 starts from the water pump end(front) or flywheel end (back)?

Engine just back from rebuild.  Will not start.  Indexed oil pump at TDC with rotor at 7 clock position.  Using 153624 firing order.  Used compression on #1  (front?), light and TDC to set initial timing.  Just back fires. ???

Thanks.

front  to rear 1-6 with one at the water pump end of the block

 

double check that compression TDC number one...could be you 180 out...quick lift and rotate of dist. shaft will let you know right quick like.

hallo,

  here is what I have for my Plymouth P23:

Your fireing order is the same.

Maybe You should look at the cap/ rotor combination.

For Dodge, there may be others.

Good luck and good health!

Greetings from Düsseldorf!

Thanks for the responses.  This engines was rebuilt about 4 years ago by a machine shop and has been stored since.  Just installed it back in the car.  Unable to get it to start.  Rechecked timing, indexed oil pump, firing order, points, hot spark, etc.  Finally checked compression.  70 to 90 lbs. which seems really low.  Any suggestions??  Thanks.

Just several backfires.  Rechecked timing, indexed oil pump, firing order, points setting, verified #1 compression stroke, hot spark, etc.  Finally checked compression.  70 to 90 lbs. which seems really low.  Maybe stuck rings? Any suggestions??  Thanks.

Was that a wet or dry compression check? Once you get started and warm up the eng, do another compression check. After 4 years your rings might be stuck. Shoot a little oil down plug hole toward the middle of the head and they should loosen up. I have a 1950 Dodge wayfarer 230 in my P-15 and my compression is about 110-115 on all cylinders, but when I got first got it the compression was about 75 to 95 psi. Also cylinders 1 and 6 ride the same except 180 degrees out. When # 1 is comes up for compression #6 is comes up on exhaust. These cars will start with low compression about 60 psi they just won't run good.

You're not running the plug wires in the wrong rotation on the cap, are you? I believe it's clockwise for these flathead 6s. I'm only guessing at things that might cause what you are describing.

Unless that rebuilt engine has been broken in I wouldn't worry about the compression numbers right now.  My original 218 shows 50 in each hole and runs just fine, but who knows how many miles are on those rings?  Might be original for all I know.

Yes, a newly rebuilt engine will not have 'normal' compression until it has been run in for a few miles/hours.

Again thanks for all comments.  Will put oil in all cylinders and try again.  I have gone over the ignition and timing set up very carefully several times including priming and believe it should have acted like it would start anyway.  I have some anxiety relief from the comments about the low compression.  Thoughts of pulling the engine out again were not good.
