On a cold start up with Eddy carbs and the fuel evaporation problems they have, my question is; Is it better to use starting fluid to get an immediate and rapid engine start or to crank the starter to pull fuel into the carbs resulting in alot of low RPM cranking/slower start? The concern is oil pressure, cam/lifter wear and general engine wear.

I NEVER use starting fluid except as a last resort. A well tunes engine will start without causing issues...except for a fresh build(no breakin) I'd rather have it crank and see if oil pressure builds.

Really? I have a 600 CFM 1406 on a small block that sits for months and months at a time, and untouched all winter. I pump the gas 6-7 times turn the key and it fires right up every time. Never had to crank it more than 20 seconds and never used starting fluid.

i think like the other poster, a well tuned carb(s) a few pumps of the pedal is all I've ever needed. Even in this 440-6 w/ a solid roller 588 cam and alum heads, 3 pumps and fire. hold it at 1500 for a minute or 3 and drive.

Once the oil pressure comes up, you should have little wear while cranking. Probably a bigger issue would be wearing out the starter.

I read once years ago that for every doubling of rpm's, you quadruple the wear. So at 8,000 rpms theres a whole lot more wear going on than at cranking rpms (again, once you have oil pressure).

Fix the carb. Leave the starting fluid for the diesel guys.

Not much you can do to fix it other than change carbs.

The cranking to start it shouldn't hurt anything.

One thing, elec fuel pump would fix the problem

IF the car sits a lot ... it could be normal evap. Just fill up the carb from the vent tubes OR use an electric fuel pump to fill.

Thanks for the input. On my other car with a Holly carb, it's no problem to fill the bowl through the vent with a little funnel. On the Carter (Eddy) carbs, there is no place to do that without pulling the top of the carb off.
I know the fix is to install an electric pump to "prime" the carb once it's been sitting. It just seems like the fuel evaporates so quickly that if the car isnt driven for a week, the accelerator pump has nothing to pump.
I mostly wanted to get your input on was if it was harmful on the cam to crank the engine until the motor fires.

No, there shouldn't be any additional wear from cranking instead of running.
Unless all of the oil ran off the cam and it is bone dry.
I just started my car after sitting 7 months and drove away. No worries.

When I had the Edelbrock on my Diplomat, it was "grind city" for the starter to get it going; another 318 with headers and Edelbrock manifold/carb,, my D 250 pickup starts easier than my fuel infested Cherokee does.

The TQ carb is probably the WORSE ...as far as evap. Just go to the DOLLAR STORE and get a pair of those mustard/ketchup squirt bottles.

And YES ...I would not want to crank and CRANK ..... NOT good for the starter OR cam. uNless you have a roller cam.

A guy stated once (on here) that starting fluid is extremely harmful and he explained why (dont remem what he said) & called it "liquid sand in a can".

Actually, there is. The vents are are smallish, rectangular holes right next to the rod covers.You can get gas in the bowl that way, but will need the aforementioned squirt bottle to do it.

I was hoping someone would bring this up...........old schoolers I know call it "very caustic" and generally discourage the use of it if you don't have to.

that is what i have heard as well.

i just have a little glass bottle filled with gas, and dump a bit down the carbs before firing it if it has sat for a while. that at least gets an initial few seconds of running and primes the carbs. then i don't have to crank nearly as much to get it going.

Been trying to remem what that posted stated for the reason (true or not true) & all I can remem is something about what the ether does. Doc you're not old school? Best trick I saw was to just loosen the wing nut a bit & dribble the gas down the stud WO having to take the air cleaner off but I'd want to wipe that area on the top flat clean 1st.

The only thing that I can think-of that would make using starting-fluid "hard on an engine" ... is that the motor wants to go sky-high in RPMs as you are spraying it.

And FORGET about using it on a diesel ...

It seems you would have to use quite a bit of starting fluid to do harm to the cylinder walls.
The all a pain in the a** with the shaker setup to even see the carbs!
