Re: Trouble shoot 1950 8Ba initial start up Help
If it has never been run since the rings were installed, the rings have probably not seated and those numbers may not be as bad as they seem. They should be sufficient to start the engine though.

Re: Trouble shoot 1950 8Ba initial start up Help
The compression numbers don't look that bad for unseated rings, so that should rule out any valve issues. So about has to be an ignition problem. Can you post a couple of photos of the distributor in place that shows the wiring harness and how it is routed to the plugs?

Re: Trouble shoot 1950 8Ba initial start up Help
Those numbers are more typical of a worn engine. As noted there is enough compression to start it. Problem would seem to be improper timing.

Re: Trouble shoot 1950 8Ba initial start up Help
Also, when you check the spark at the plug, is it a bright blue spark?

Re: Trouble shoot 1950 8Ba initial start up Help
If you are serious in trying to get this started, I suggest removing the dual carb thingy, bolting your best carburetor directly to the manifold and replacing the spark plugs with new ones (the existing plugs are probably very compromised from the previous attempts at priming the engine in various ways). Make sure you still have spark and gas to the carb. Give it one more try before tearing it down.
If it still doesn't start, you might try turning the distributor 180 degrees and resetting the timing. |

Re: Trouble shoot 1950 8Ba initial start up Help
If you’re using repro condenser and points they are junk. I had problems on initial start up because of weak spark. Bought NORS condenser and point and it started right up.

Re: Trouble shoot 1950 8Ba initial start up Help
Appreciate all the help! Spark is BLUE
New 12V harness installed for complete car Power Master starter and Power Master generator Which is an really an Alternator These are the best $600 with tax between the two 12 volt system and new battery that I charge between intervals Starter is strong and fast I am going to convert to adjustable lifters and a new intake Between the two I think I will have exhausted the issues Yesterday Sprayed ether and poured fuel down the hatch again today and still the plugs did not smell strong of gas or ether as they should nor did they appear wet . I think that hokey carb set up is bogus and maybe my 94 rebuilds suck although they are squirting??? It’s almost like there is a blockage which is why I am going after the induction set up Last edited by Bustingear; 02-26-2021 at 06:42 AM. |

Re: Trouble shoot 1950 8Ba initial start up Help
I think the cam gear dot is three teeth to the left.

Re: Trouble shoot 1950 8Ba initial start up Help
Just a suggestion, before I did anything else, I would remove the phony dual intake (as previously suggested).
Mount a single carb and try it that way.

Re: Trouble shoot 1950 8Ba initial start up Help
question regarding distributor vacuum advance. currently one of the 94 carbs has the vacuum port built in. If i switch to a different 94 without can i run the vacuum advance line to an aluminum spacer between the 94 and the manifold? Will it work there?

Re: Trouble shoot 1950 8Ba initial start up Help
Is the distributer gear on the cam correctly installed and is it tight
so as not to rotate when it meshes with the distributor gear? |

Re: Trouble shoot 1950 8Ba initial start up Help
No, the stock distributor requires ported carb. vacuum to operate correctly, not manifold vacuum.

Re: Trouble shoot 1950 8Ba initial start up Help
No, that distributor requires a specific carburetor to work. It needs a mixed signal from both above and below the throttle plate.

Re: Trouble shoot 1950 8Ba initial start up Help
It should do something with starting fluid and the compression readings you are getting. I'm unsure if adjustable lifters will accomplish anything at this point. Do you have another stock distributor that you can swap in? Maybe the Petronix is flaking out...
