Need some help guys. I have B5 with the updated carb. It was running great through about 3 gallons. Then at the Nats during my main my clunk broke inside my tank. It didn't blow up or go to pieces but it looked like the filter part just came off the little metal tube that goes in the fuel line. I ended running about 3 or 4 more laps until I pulled the car. Not sure how hot it got but it was def HOT. It would drive ok until I'd hit a big jump or bump which would cause the fuel line to get air instead of fuel.

Ok now the issue I'm having is holding a steady idle once the engine gets up to temp. I'm worried that the engine might be done b/c its acting alot like an old engine. It will idle good but once it gets hot the idle will hold for 7-10 seconds then drop off quickly and want to die. I've messed with the settings and it seems to react the same way no matter if the bottom is fat or lean. Also tried new tank and plug.

I raced it last weekend at the same track and had two flame outs. Then I did some testing in the backyard yesterday(sick home track) and it was still having the idle issues.

Any thoughts would be appreciated.

as Razathorn stated always check the clutch first... if its good check compression... I let a buddy borrow one of my engines and he had failed to tighten that pinch bolt..lol long story short, he gave it back shortly after completing his run with it at 400 degrees...lol good thing hes a buddy!!!! anyway.... needless to say the compression wasnt the greatest:lol:
I had Alan Burton from the Speed Shop do a repinch on it and I ran it this past weekend no problems at all..
you might have to go that route, these engines are pretty durable, I spent 20 bucks to Alan Burton and a new plug but thats it.
something to think about anyway.

To be honest that is about the only thing I haven't checked yet. But it was pretty new clutch, bearings(i change my clutch bearing pretty much everytime i pull the end bell off) and end bell prior to this last race. So I really don't think that will be it but that is my next plan. I'm going to give it a good clean and see what happens.

I've had bearings go out on me after just one run. Some last long some don't. But hopefully, something simple like that is your problem and not the engine.

I was running a P3 and then went to a 97T which seemed to run better.

My current settings are about 2.5 out on top, 4.5 out on bottom(looks like about 1mm in from flush) and appox .5mm idle gap.

Idle prior was pretty solid. I wouldn't say perfect, had a bit of high rev prior to dropping but would then idle strong.

I'm running Byrons 40% and live at about 5500ft.

light, medium and heavy flywheel...medium on the engine

Thanks For posting that Mo!

I was wondering what collet you used. Would I use the one that came with my Mugen or the B5 or does this come with another collet to match the flywheel?

I run Mugen stuff for now and I used the collet that came with the clutch.
I took it out of my buggy to inspect it a few races back and dropped it so I tryed the stock mugen collet and it wasnt long enough. so if you use the mugen collet I think you need shims behind it.

just spoke to ron......he resolved my issue completely. he is truly a credit to this industry. he, as well as his products, continue to excell......thanks again, ron...

This and this alone is why I bought a werks motor, getting a kick ass motor was just the bonus!

i've raced with a ninja, v-spec and jammin engines.....this WERKS B5 is by far the best of the bunch.........

Yeah, they're great. The price and customer service is icing.
