Got my engine apart // When I try to run it before it would only run on prime // Have ck'ed the needle passage and all is clear , I did just replace the hose that had a small kink in it . Q is there a O ring that goes on the Ventura ? (I cant tell from looking if there was ! Thanks Eric Huh...

And will it go together without the rotor catching the crank-pin??

I have never worked on one of those so I dont know but, it seems to me the crank pin would have to stick through the rod and engauge the hole in the rotory valve. Therefore I wouldnt think it would go together if not aligned. I would think there must be an oring on the backplate to ever be able to get a needle adjustment on it. The other thing is looking at the picture of the rotory valve, I cant see how it could work at all without another hole in it.

It looks like the gasket is smashed onto the tube, you probably need to replace it, small 0-ring or thin slice of silicone fuel tubing.

If you try hard enough you can screw down tank without aligning pin, trial fit first.

I thought that was an o- sealer there (but) I will take it apart and replace with tube cut , I think I got the putting it back together now, a little tricky a lot diff than a Bee for sure Small Cox Logo

I see I'm going to have to dig up some pictures that went missing.

Thanks Admin , I had seen this before but nothing wrong with reminders , I have been making them awhile but have not tried the skewer . I have been using a sharp pair of small dikes and stretching the ring over the tube with a probe pick and my finger nail holding it in place. Haven't tried the floppy disc for reeds but need to just another way to cut back on expenses. Eric Very Happy
