Re: starting issue
Bob, don’t give up. Don’t take this forum personally. This world is losing REAL people who can actually rebuild things. Most people on the forum would install a used item before rebuilding. I call them RNR experts. Plus no one likes to hear things straight forward. It’s only opinions here. We both know once the vehicle comes into our shop we can fix it. This arm chair stuff I only use it as a good laugh. Anyone can copy and paste on their computer but to explain it in their own words forget it. Good luck to you. Enjoy retirement !!!! Let’s go fishing

Here's a "cut an paste" from another forum about the same issue. https://www.pistonheads.com/gassing/...f=12&t=1220583 Youngpup, don't get on me, now. () "It is also possible if there is a big enough current drain at the starter that the ignition system will be robbed of spark, this can be enough to mean the car wont start even if the starter cranks.

Re: starting issue
It’s all good. Just trying to have a bit of fun at times is all. I know in today’s world the internet is where every one has their knowledge. I just try to keep it between the ears.

Bob, if you're still around, I'm also retired and was a member way back when the site was fairly new under "zmire". I've really learned and helped others at the same time. Great site even though we have an occasional post that can p-ss us off, it's not a reason to leave. No suggestion or question should be discarded quickly. Should be always welcomed.

Re: starting issue
I'll throw out some info, to try to help OP out a little. I recently swapped out my Edelbrock 600 cfm (1406) carb for a Quick Fuel Brawler 650 c electric choke. I was having the same symptoms as you are reporting. IIRC, when I installed this distributor, I was in an hurry, set #1 to TDC on compression stroke, fired it up and adjusted by what I heard from the engine. Truck fired fine when hot with the Edelbrock. So, I installed the 650 Brawler (Holley, essentially) and from that moment on had hot start issues.
When I swapped carbs, I moved away from an electric fuel pump and went to a mechanical fuel pump. So, i kinda figured that my issue was too much fuel pressure (I'm sitting around 8-9 PSI right now and need to install a regulator. I too got annoyed by my truck not firing right to life. Not to argue with anyone above, BUT, my '59 Apache with its SBC AND my '68 GMC with it's new Mk. IV BBC both literally fire up faster than either my new fuel injected truck, or my wife's 2016 Toyota 4Runner! And both of those vehicles are in top top shape. Cold, I give either truck two pumps of the accelerator pedal. Hot, I dont touch the pedal. Anyway, I digress. When I had the issue that you are explaining, it was bothering me, as I re-jetted the carb for elevation, adjusted my float levels and carefully adjusted my four corner idle adjusters on the new carb, with a vacuum gauge and tach under the hood. Still hard starting when hot, I thought it was a high fuel pressure issue, but knew that I needed to rule out timing. I run 91 octane in the truck and live at 6,900' ASL, both of which give me a little leeway with timing. When I put the light on it, it was so far advanced that I literally walked over to the passenger side to look at that side, looking for my timing mark. It was at about 12 o'clock, advanced WAY too much! I literally threw away my old dial back "adjustable" timing light, as I had trouble with it in the past. So, I went back to a regular old timing light, no advance on it. I'd guess that my initial timing was north of 25°! No bueno! So I adjusted it to about 14° initial advance and voila! No more hot start issues and runs like a top. I checked timing with engine warmed up all the way (thermostat open), with ported vacuum advance hose pulled from distributor and plugged, though I not sure that's necessary, with ported vacuum line to carb. I'm not 100% certain of my total timing, as I'm operating with just the metal timing tab that goes to about 16° and no adjustable timing light. So, if I had to guess, I'd say that you too have probably pulled too much timing. That gave me the same exact symptoms as you described. Hope this helps a little. Figure out your timing! You can get a decent timing light from a parts store for $30-$40. Its money well spent! Plus, I think that it's fun and I get some weird looks and questions from neighbors that have never seen a timing light! Good luck, Nik
