QUOTE (bd1308 @ Jul 15 2005, 09:12 AM) i said low vac on another thread and i got my ass kicked. just ignore everything i say, seems to work out better. No butt kicking here - just wanted to clarify that on Earth, atmospheric pressure is nominally 14.69 psi (at sea level). Therefore, a perfect vacuum would equal -14.69 psi or ZERO absolute. No such thing as 20 psi vacuum on this planet...thus the question about your planet of inhabitance. (IMG:http://www.914world.com/bbs2/html/emoticons/aktion035.gif) P.S. I make it a habit of getting corrected around here, too. It's good for the soul to know that I don't know it all.

Maybe he was thinking in terms of inches of water column???? (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

For tractors and stationary engines for generators/pumps I bet (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

This one of those items that just about anything could be used with success or disaster depending on the person doing the install.......

Could be, but 20 in H2O is only 0.72 psi - not much vacuum.

Bill: The reason I can take the pictures of the injection stuff is because, after almost 2 years of chasing failures in the injection system, the onwer of this one drove my carbed car on a run and desided to stop throghing money at a dying system. About $600 to covert to duel single Solex 40's. Thats less than her last bill at her machanics, and the car stills was trying to commite automotive suiside. I'm giong to use a 009 dist with an Igniter, and a Brush exhuast. It won't be a hot rod but every time she puts the key in the car it going to start.
Jeff Bowlsby is not far from you and he is a Garu. Seek him out and score a loom, look at his cars for correct info on the assembly.

Are you calling me a country bumpkin (IMG:http://www.914world.com/bbs2/html/emoticons/mad.gif) ...Well I'm bit of a redneck I guess (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

How did you know I use a farm supply guy (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) Delivers my hardware right to my door. (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)

Thanks for the replies. Much helpful information.

Dave, the engine was rebuilt at the same time it was converted to carburator. However, according to the paperwork it was rebuilt with the original camshaft, so hopefully that won't be a problem.

Joe, How can I find Jeff Bowlsby?

[bd1308]

yell real loud.....

he frequents this board quite often....pm him...

[JoeSharp]

Check the resources page here. He makes harneres for all of your needs.

My MPS leaks like a sieve. I pump it down to 20in Hg and it leaks to 15 within a minute. Any suggestions on where to get it rebuilt or to get a replacement at a decent price? Perhaps I should consider converting to dual carbs.

[Bleyseng]

how much does it leak in 5 minutes?

[billd]

Its down to about 8 in Hg in 5 minutes and then holds fairly steady, 7.5in Hg in 10 minutes.

[bd1308]

go megasquirt man.....

[billd]

So what's involved in a 914 2.0L megasquirt setup? Can someone point me to a guide.

[bd1308]

uhoh. i'm going to get yelled at now.


whenever i talk, people get mad.

do a search for megasquirt, you'll find like oodles of information

people have done the work on fuel maps and such

i think general people know about these things well enough to work on them (dyno wise)

buy a cheap laptop if you get serious into it.

I have a couple of laptops.

[billd]

Is megasquirt the only aftermarket EFI option or are there others?

[bd1308]

for me personally, megasquirt is the only way


for everybody else, it's the cheapest

there's one called the Kit Carlson (or used to be anyway, he stopped doing them last i heard) costs over 1k

MS is like $500 or so with the box and maybe a harness queaking through.

[lapuwali]

Megasquirt isn't the "only" way. See my blog for a short rundown on the various aftermarket systems in use on the 914. Search for DNHunt (Dave Hunt), who has had MS running on a 2.0 914, and will have it running again on his 2270 once he's finished assembling it.

[Bleyseng]

Thats not too bad so I would assume that something else is your problem. A blown diaphram in the MPS results in 0hg in like 2 secs.

I haven't followed all the problems on this engine. Please review them, ie: whats it doing??

[billd]

The only problem with the engine is that it currently has a single progressive 2 barrel carb and I'd like to convert it back to EFI. I'm checking out the components before doing the conversion.
