Won't start

[garbagestate 44]

Hello gentlemen,

I have a 47 Chrysler Windsor that doesn't want to start. I've done everything except sing to it. To date I've replaced pistons and rings, 4 out of 6 wrist pin bushings, 1 exhaust valve, points,plugs,condensed,rotor, breaker plate,coil,all the usual stuff, did a compression test and got readings dry between mid 60's and high 70's, A number that I suspect will go up after the rings are run in. The sisson choke tends to flood the engine since all that crank time pulls all that fuel in from the idle circuit. It trys to start but tanks after the engine floods. I've static timed the engine as per the site tecnical section. The thing does everything but run. Anybody have any ideas? Thanks

John

Your compression readings sound a little low to me. Have you checked the timing chain for being stretched or jumped?

The timing chain was the one thing I didn't check. As far as the compression being a little low, I figured that those numbers would probably go up once I ran the engine at high rpms and the rings seated. My ford y-block had a bent pushrod once with zero compression on 1 cylinder and it still ran. It ran like crap with buckets of smoke but it still started.

If you have indeed flooded your engine then the first thing to do is clean the spark plugs. A sand blaster works best.

If you think it got flooded pull the plugs and clean them . Do you see fuel on the outside of the carb? If so your float level may be too high. Check the float level clean the plugs recheck your timing and firing order and try again. When I installed my rebuilt engine it wouldn't start. double chceked everything it was all good except, I had the wires indexed one tower off in the cap, redid that and it fired right up.

If you're doing all this cranking, you're washing the cylinder walls with gas. Maybe throw some oil down each cylinder for lubrication.

Thanks for all the advice, I think I may go to a manual choke while I'm at it. There's a couple of junker carbs on ebay right now that have the correct linkage.
