Hello Members,
Having recently completed my Hoglet, I thought it may be of interest to pass on a couple of the problem areas I experienced. Took a while to overcome the"blowing" instead of "sucking" of fuel. This was fixed by setting the valve timing to the appropriate cylinder. Fitted CI rings rather than "O" rings. This was a personal preference. Made the 20 tooth crank sprocket with an extended boss which allows the fitting of 2 x 3mm socket head grub screws.
If the specified tapered socket head cap screw should come loose it can cause a major mangle -up of the Hall ignition timing arm etc. [I found out!]
The carby specified is no longer available. First carby was a design which I though would do the job. Just dumped fuel. Gave up on this one. Was using 91 0ctane petrol/oil mix. Bought a 10C of OS brand. This gave some running life on methanol, but again I could not overcome fuel dumping to sustain continous running. Current situation is a carby to the plans of Gerry Howell`s 2 jet model. Good detailed specifications, a test of good machining practices plus an adrenalin boost when drilling the 0.018" jets. With a fuel of "Shellite" [Coleman`s fluid?] with 5% WD40 I have achieved an instant starter with a low idle to a good top end. I am convinced it sounds like a Harley. If I can work out how to post pictures I will do so.
