How to Start a Carburated Motor in Any Situation
KMD88 posted a topic in 1969-70 Technical ForumThis is embarrassing, but I have to put my pride aside for this one. I've had my 69 Mach 1 since March. I love it, and I've been very lucky with the condition it was in when I purchased. I was considering going EFI to make life easier, but the mechanic I work with was pretty against it; citing nothing but problems with each conversion he worked on previously. I have a 351 Windsor, and besides an engine swap, he told me to stay carburated for the time being. In addition, the mechanic said the carburated looks to be timed/calibrated properly. I'm fine with this, except I just can't seem to dial in exactly what the car needs to start sometimes. Here's what I've deciphered: When I haven't driven the car for two days or more, two full, slow pumps on the gas will do it. When I drive the car around, leave it for 5 minutes, then start her back up, I just put my foot 3/4 of the way down on the gas and turn the key. Starts right away. But after driving, then leaving her for an hour or two and coming back, it's sometimes a crap shoot. I've flooded the motor a couple times trying to figure it out. So all this is to say, is there a rule of thumb or a method to really know what the engine needs? I'm getting my car back from the mechanic this week, and I don't want to be the newbie that can't start his own car right away. I've searched online for help, but there's very little about starting carburators online. Or maybe I'm not using the right search terms. Either way, would appreciate your advice. Again, embarrassed to ask, but you have to start somewhere. Thank you.
Conflicting carb advice
six_sigma posted a topic in 1969-70 Technical ForumHey folks, So I have rebuilt roller 302 with an RPM intake, B cam and Tri-y's. I have an Edelbrock 1406 600cfm performer carb and it's running quite rich. I was told, and had read in a few places that a 500 CFM carb is really the way to go, so I found a used on for a good price that was on a V6 chevy motor. I installed the carb and I can't get the car to idle below 1K RPM, previously is was idling around 750-800 with a nice burble. So I go to a specialist carb rebuilder to ask if they have a jet and rod kit for the carb and the old guy says that the 500 is too small and the engine is going to run lean. so now I have 2 carbs and more confusion. Any of you guys care to add to my store of conflicting knowledge? Thanks in advance.
