Thinking 'bout converting to electronic igntion

Post by Roge1 » 06 Nov 2015 04:01 pm

Hey folks,

Can anyone advise on the easiest/most cost effective way to convert my 1985 340 (B14 engine) from manual choke to electronic ignition, or recommend the best kit etc?

Something I've not really looked into before, so your experience and guidance would be greatly appreciated.

Thanks in advance 340pw

Hmm would you like to rephrase that?

A 1985 will have electronic ignition and a manual choke. There are no auto choke models and you don't want one. If you mean fuel injection, again there are no B14 injection models and it would be a big undertaking.

What are you trying to achieve? The 1985 B14 is fine with correctly adjusted carb and computerised ignition.

Hi and thanks for the reply. Main 'gripe' is that the engine has never run well, even after a carb refurb, service, etc, and every time I use the choke it seems to burn a lot of fuel regardless of how sparingly it is used! In all honesty I've had varying issues with the engine, specifically the idling aspect, over the last few years, and was just interested if there was anything worth doing to make the driving experience 'easier'!

Clearly something not right with it. Check the breather is properly restricted at the bottom of the carb by blocking/squeezing the pipe. If the engine sounds different the restrictor is missing.

I do prefer injection but you need a 360 GLT for that, or major engine + support system changes.

How easy/difficult is it to source and replace the restrictor, if that turns out to be at fault?

Thanks again.

You can just roll up a bit of paper and put it in the pipe attached to the bottom of the carb for temporary repair, it depended on year if the restriction is in the pipe or the T piece at the valve cover. You can make something easy enough.

I can see the attraction of swapping a points-based system for Renix ignition (hard to get good points these days) but you've already that installed from the factory as Ride_on says ...

Good luck, and let us know how you get on!

Cheers
