Oh.. I remember when... it was just a little pile of unfinished parts... gears not hobbed... pistons not grooved... ignition not made by a 12 year old Chinese girl... You have come a long way!!! :headbang:
Looks very nice... Once it is straightened out, you can put it on your mantle so when your friends come over and ask you "what do you do with it?" you can answer... "Show it to you... and no, I am not going to hook it up to anything..."

Ho ho ho, Kwackers. Hope all is well, not spoke to you in a while as I`ve been on hols. I bet it has been heaven without the constant mithering ;-)
Rob - cheers. Glad you thinking it is looking better.
Just a quick update, I have extended the intake line again as Stew posted many pages ago and this seems to make things miles better! I know this seems stupid, but I think I`ve been flooding the engine with too reach a mix. I`ve also reverted back to the intended use of the vapour carb. Back when I couldn`t get the engine running and I thought it was a fuel intake problem I extended the inflow pipe to pull in fuel below the fuel line like Jan Ridders original bubble carb. I`ve not reverted back so the inlet is just blowing over the top of the fuel and disturbing it rather than bubbling through it. I can only presume this has again reduced the richness of the mixture and has also enhanced the performance of the engine and makes it much easier to control via the air/fuel mix nut (remember I was having problems with this not doing anything). The engine seems less fussy now about the perfect position of the air/fuel nut and more reliable. I think perhaps a few more nights of playing, polishing and it should be running better. Fingers crossed.

This is why in new revisions of Jans carbs, and my redesign for the Otto, the intake comes out of the top of the tank instead of the side. You can eliminate most of the sucking of raw fuel into the engine by filling the tank below half full...
