So when was the carb changed? I've had mine NIB for about 6 weeks and it has the old carb. Am I going to have problems with it now? I always seal up my engine good. Was that the only problem with the old carb or will I be chasing the tune all day?

Theres nothing wrong with the old carb. I just got back from racing with my B5 with the old carb and it held a tune all night.

Jaz, my B5 has the old carb on it... which i happen to like very much. You've seen it run, you'll have no problems with it.

Ya, there is nothing wrong with old carb at all. That style has been out for years and has been great and has been used on many engines with great success.As with all things Ron found a way to make a bettter one so he did. But there is absolutly nothing wrong with the old carb, the change was done not becasue there were ANY isssuse's with the old carb. But because they made a couple new changes and it worked great.Most of us on here have the old carb version and have no issues at all. I guess some more of us need to but another one to check out the new carb Well, its a good enough excuse for me! Im gonna have to order another one!

smb17, how did your racing go saturday with the B5 and the WERKS fuel?

Ok cool! I thought the carb was changed because of issues..I'm all good now

Hey Jaz, as the other guys mentioned there is absolutely no problems at all with the older composite carb. I'm just a big believer in selling the best products that I can and if during the production of an item we figure out a way to make it better I incorperate it. That's it!

Hi, Im interested in your engine but I cant find info on your website on the B5 By all the great reviews im thinking of buying 2, 1 for the RC8 and RC8T-CE.

Hoenestly that's becuse our site has not been updated in a while lol! Frankly it's old and archaic and I'm starting to work on a completely fresh site instead of trying to keep making that thing work! Unfortunately there is so much going on right now that time is a little short though. You should be able to find specs and everything on the a-main product page, were you looking for any specific info that I can give you?

Regards,

Ron

Well I have the thread out Reedy 121vr or Jammin jpx for my next engine and now I am considering your's big time. A big thing for me is parts availability, customer service which seems spot on.{ example} will I be able to replace piston-sleeve-con rod? The engine speeks for itself I think ,cool temp, reliable, smooth consisant idle, longevity, power what more can you expect from an engine! PS. I think it's great your on here supporting your engine and customers.

heidmann1, It was fun. Gas tank lid got stuck open in the main so I had to get re fired. I think I might bump up a class. I'll be mid pack but that's okay . It was a pretty low turn out. Just need to get that x2 planted better and roll through the bumps better. No engine issues though. I can pull people in down that straight. There's power any time I need it. Fuel is good too. Everything is nice and coated.

This engine is so inexpensive that any time you need to rebuild you can just buy a new one. The new one will have all the updates!

Buying a B5 is cheaper than rebuilding my RB engine!

Quick update ... 7 tanks into the break-in and now have the idle set around 1mm. I finally removed the head wrap to let the engine reach temps with semi-rich settings. I understand the needles are different for everyone, but I wanted to share where I'm at right now:

Carb: 2010 version
Ambient temp: 70F
Humidity: 90% (yes, really)
Operating temp: 200F
Plug: OD 77T (still have some from the last engine)
Pipe: GO 2072 (Werks 2013 on the way)
Fuel: Byron's Pro Race 30% / 11% oil
HSN: 24 hours in
LSN: 12 hours out

This is still running rich, but makes for a glorious sounding idle Takes off well from a 30s idle.

You do have a point there about just buying a new one instead of rebuilding

Yeah thats what I like about it. When your current B5 is done. You can go buy the most up to date one.
