Chris, are you on skype??
I am douglas.vanderbilt... look me up...
raynerd:
Hi Doug, I`m not, but I`ve always fancied giving it ago, infact I did a year or so ago so I`ll reinstall over the weekend and look you up.

Hi Chris,
Did you read Dougs response? maybe not worth spending too much time making a butterfly valve then.
Thanks for that info Doug, Love the Otto by the way :beer: .
I'd decided to get mine running first anyway then I can play :D.
Steve.
raynerd:
Hi Guys, yes, sorry missed your last post Steve, yes I have seen Dougs post and will need to think of something because I can`t control mine at all!
Clearly the money I spent at Harrogate yesterday was well worth it as only having the new equipment present in my workshop I managed to get my engine con rod built and back together again. I did say I was going to strip it for final polish and assembly but when I`d built the con rod, I just couldn`t help giving it another way.
So don`t get me wrong, I`m well chuffed, it runs, I`ve built an IC engine :ddb: :ddb: :ddb: :ddb:
But I don`t have any control at all over the throttle. There seems to be no "give" in the air intake position, too lean or too strong and the engine is just killed. I have had it running for many many minutes now but I`ve taken these photos to show you my problem. They are not necessarly the best examples of smooth running, just that it is working but I can`t control it.
Like I said, if I play with the air regulator on the vapour carb it just cuts it dead, the only slight control I have is if I put my finger slightly over the air intake into the vapour carb. Even then the control is so tricky that I often end up killing the engine as shown in both clips. The engine will run for several minutes until it is too hot and I knock it off but I can`t control throttle at all.
I should stop moaning - it is running!! :drool: :ddb: :ddb: :ddb: :ddb:
I think I`m going to get rid of the bearings in the main frame, they are light duty and I`ve already smashed 2 so I`ll just bush the holes. I`ve sprayed some WD40 on the valve blocks to look for leaks and there is some fizzing from the screws so I need some gasket compound here. Also, as suggested I have put a piece of tubing on the vapour carb to make it act like a bubble vapour carb. I think maybe all this splashing is causing the mix to be too strong and inconcistent, maybe it is worth taking this off. I also got a nice piece of alluminium for a new base at Harrogate yesterday so I think the plan might be to strip down now it is at least running and have a better troubleshoot to get it running just right when it is in a state more ready to display.
So anyway, proof is in the video, I have a runner :D They only cut out because I`m trying to slow them down and cut the air intake.
Thanks for the help of everyone and I really mean that. I wouldn`t of stood ANY chance of building this and getting it running without Madmodder.
Chris
