Here's some examples of chain guards on various types of engines.
All I believe are acceptable.
Hi Steve and Allan,
Thank you for your replies, but I agree to disagree with your comments. Steve -
Carbys still come loose with nylocks. Allan - The man mentioned the carby came off, and he stuck his hand in the rotary valve. Hello! No fingy .
I am not only refering to Rotary Valve engine, but also Reed, and all other engines in Vintage Karting.
Max - Get over this *racing* crap. I know we are not, but it only takes one lap for these things to come loose.
I just want to know what the official rule is, so that I can get my karts passed. I do not want to go to a meeting where they are sent home as illegal.
As far as the member that jumped out of one kart and into a other rotary/reed, that is easily done.
We are not getting any directions here in Vic as far as this rule is to be complied to.
So Heath Butt - Can you please, as Chairman of Vintage Committee put up on this Forum what the BLOODY rule is please.
Just luved your meteorite comment, my sentiments precisely??
I was "Challenged" last time out on the green kart which is how it has run all its life as far as I know, the rule is certainly unclear.
This is a reaction to a guy that jumped out of a Rotary motor, straight into a Reed Motor .................. Now with a reed I can see some logic.
1) we are not racing.
2) Supposed to be "True to detail?"
Is this all OK?
I are not sure if there will be any other Victas (or Macs) at the Bolivar VGP in May. But if there are, they may have their hands full chasing this one! It has not been fired since the 70s, but is about to be. Stay tuned! More of a slasher than a mower this one! :)
You are most likely right about finger guards specifically. In my post I could have specified finger guards being part of the "chain guard", probably should have. I have not read "the rule" (I'll do that right now) in fact & apologise if that was what I wrote or implied.
I was advised by telephone some weeks ago along the lines of "chain guards the same as what had been required in the day". The original post I reacted to was one saying chain guards were not used on many Era 1-2 karts and they had not been required originally. Since I started racing in 1965 chain guards which morphed into chain/finger guards when rotary valve engines appeared had always been mandatory but in early days the term "chain guard" would have been used extraordinarily loosely!
As far as notification is concerned there was an item in a VC Committee minutes received by QVHK 25/10/17 referring to clubs being notified:
However we (QVHK) had advised our members of this looming issue in a letter 20/10/17.
In fact this was a result of it being aired, I think, on this web page & others as well
This is the rule from the 2018 KA manual:
10 Chain Guarda) Notwithstanding the requirements of Rule 8 b) herein, all Vintage Karts must be fitted with an operable chain guard.
It's taken as read, I think, that a chain/finger guard as per the requirements of the day would be more than adequate.
On the issue of nyloc nuts Stephen Moxon's post referring only to slide carburettors requiring to be affixed by nyloc nuts is the current policy as per my enquiry today..
However personally I would put having a carby completely fall of in the same category as being hit on the head by a metorite!.....?
Based on my enquiry today:
Nyloc nuts is a "recommendation" on rotary valve engines.
There is an acceptance by the VC that a slide carburettor (properly in place with nuts tightened) would act as a finger guard so in that case the rule is partially satisfied.
Rod, it is my understanding that if slide carbys are used, nylock nuts are required to affix the carby. I maybe incorrect, anyone else?
Sometime in the last 2 weeks a question came up about the new chain guard rule.
Peter Ward. You and Allan King said that the new rule quoted that chain guards had to be fitted. You showed photos of chain guards fitted in the 60's.
Well - sorry, but my interpretation of this rule is that the fingerguard, namely sprocket, has to covered as well.
I just want this rule to be verified, as there are different standards on it from what I can understand.
Maybe someone from the Vintage Committee can verify this to me and all the other members.
Someone came up with the bright idea that a slide carby would do the job. Well hello, one of our members loss part of a finger because the bloody carby fell off!
Please give us all the right answer.
The two orange karts, apart from same steering wheel and 4" wheels, both have a small flat panel at top of steering hoop which steering shaft goes through. The pic Ian posted of Comet/9E appears to share all
these features....so good chance orange karts are Comets. DT
To those that showed interest in the old Repco / Offy / etc speed cars of yesteryear.
I made contact with Cullen Bullen, those cars ran at their last meeting and will not be there again until next season.
Looks like we missed them for this year but the guy will keep me advised for next season.
