Enige is not running smoothly

Hi guy's,

Here I am back with another question, hope you can help me.

My engine ( BA4, carburated 2l) is not running Smoothly.

In first and second gear at low rpm ( 1000-2000 rpm) the engine starts to sputter.
this is very annoying, especially in traffic jam.
It's worse when the engine is cold, but it's also a problem when he is at temperature.
This was alway's present but it's getting worse...

Another problem is that my engine dies after starting it, the choke seems to be gone is gone.. Maybe it's only in my head, but it seems worse when it's warmer outside.

Is this al carb related or do i have some other problems?

I will try to post some movies.

Re: Enige is not running smoothly

Hey there! I recall a while back that you had a "dieseling" issue with your car and you said that you had fixed it. That is great news!

This sounds like your idle adjustment is off OR there may be "trash" sitting in the seat. I sure wish I had a diagram of the carbs. Not sure about these carburetors, but on other carburetors, there is an Idle adjust screw that is basically a type of needle and seat that meters the amount of fuel mixed with the air at idle. On those carburetors, sometimes turning the screw all the way in and back out fixed an idle issue by clearing the path. It can also point out which carb (if it's only one of them) is causing the rough idle.

The MOST important thing is if there IS an idle screw and you are going to turn it, that you count the number of turns it takes to screw it in... so you know how many turns to screw it back out.

Seek out an old motorcycle mechanic near you.

Re: Enige is not running smoothly

Unfortunately you have a carb'd lude, which almost no one here has experience with. I have a couple of suggestions for you. The first suggestion would be to try to contact a member over on the preludepower.com forum named TripleLude (Joe). He has quite a lot of experience working with these carbs, and maybe he can help you out. The other suggestion would be to try to find someone local to you who can work on these carbs. A bike shop might be able to help (as suggested by bykfixer), but I suspect that they'll take a look at the fuel system on your car and send you on your way. It's a lot more complex than any motorcycle I've ever seen.

Whichever path you decide to take, don't try messing with the adjustments yourself without at least discussing this with someone who knows what they are doing. There is also a troubleshooting section of the online manual which you can try going through (http://www.1funryd.com/hondapreludemanual1988.pdf). It's very easy to mess things up more than they are now if you don't know what you're adjusting.

Re: Enige is not running smoothly

^^ exactly...all that synched goings on.

OGSMAKDADE told me of a gray haired motorcycle guy near him that showed him all the sync know how for his CB750...that's why I keep suggesting motorcycle mechanics. If anybody locally knows, they would be a great candidate.

Re: Enige is not running smoothly

I totally agree with you about taking it to a bike mechanic Mike. I'm sure they can help him if it's a synch issue, as the process to synch carbs is pretty much the same. I'm just not sure they'll want to get into any other issues, of which there can be many with this engine...if the issue isn't carb synchronization. Once they are running correctly you almost never have to mess with them. It's when they sit without being driven that the problems start, especially with ethanol blended fuels. I'm not sure about the gasoline in Belgium, but in the US it's getting much more difficult to find any gas here that isn't blended with ethanol. In some states it's not even available anymore. I have a place near me that sells ethanol free premium, which is what I had been running in my lude for the last 5 years. It's typically about 40 cents a gallon more than "normal" premium gasoline. Which is part of the reason that car was no longer my daily driver.

Re: Enige is not running smoothly

I mistakenly used the word 'stumble' when speaking of OGS. That guy is the most prepared person in the grand scheme of things of anybody I know under 35... Apparently he skipped puberty at 8 and was in 'grown man' mode at 12...
I think he joined motorcycle forums before he purchased his 1971 bike. It may be how he scored it.
I found some how to tips for polishing alluminum engine parts to look all sparkling new at motorcycle forums. I get a lot of tips n tricks and ideas at "alternative" sites from the japanese sport cars. Super Chevy and other super-duper high priced muscle car sites are loaded with expert advice from the guys who bought 'em off the lot back when and have kept 'em going decade after decade. Some of the cars are in their 50's and 60's.

Anyway...you're right Mike, ethanol is the carburator's enemy and time is ethanols best allie.
I hear of places in Va with ethanol free gas. Marinas seem to be the place for that. Being 50 miles from the nearest one I load up my fuel tank with marine fuel stabilizers like Lucas Oil or the brown Sta-bil. Some swear by Seafoam but I'm afraid of what that might do to all my parts n pieces held together by gunk and luck.

Re: Enige is not running smoothly

I had the same issue, I have to replace the distributor and the stalling went away. Mine still idles rough when it's cold, but once it warms up no problem. Hope this helps.
