I am on my last nerve trying to get my 74 1.8 ltr L Jetronic fuel injected car started. Bypassed the seatbelt interlock to get the starter to work. Hot wired the fuel pump to get it working and still no go.

I am considering a carburetor conversion and see that Redline has a few kits. The dual carbs system has no choke and the single carb with electric choke has some distance from the cylinder heads. Anyone have any success they could share?

I'll play along... (IMG:style_emoticons/default/devil.gif)

It seems the community has gone from:

1. Put carbs on - Early years when old schools couldn't figure out the FI
2. Don't put carbs on - Mid years when shade-trees dug in and became more knowledgeable than most old schools on FI systems. Parts were plentiful. They were/are correct.
3. Here and now...

Here & Now, harnesses are brittle, good parts are getting harder to find and, a good FI system requires a knowledgeable tech trained in the art of 50 year old FI systems. My take is, if your system is stock and you have all of the components, it may be worth a shot at saving it. That said, you can easily spend thou$and$ with MPS rebuild, TPS Rebuilds, leaks and bad wiring (a $500.00 harness from Jeff B. would be an EXTREMELY wise investment).

I guess my point is, I feel carbs can be a viable alternative as we are beginning to run out of stock FI resources. Good parts are just getting harder and harder to find and, it's an old system. ***They (carbs) will make less power when run on FI cams*** As you move forward plan on a motor rebuild with a substantial cam to take advantage of all that carbs can offer.

If you're considering an engine rebuild, I would go 2258 with the new stroker cranks out there and run either carbs or EFI the likes of The Dub Shop's Type 4 MicroSquirt system. An EFI system on a motor like that will change your world.

So...

*Try to keep it alive if you can.
*Don't feel bad if you have to go carbs but, look to the future and make sure you have your eye on the proper cam for the motor eventually so you can take advantage of them.
*Did I say look to the future? Modern EFI systems can be almost plug and play these days and they will reward you in technological leaps and bounds. It's amazing.
