Jim won't run ??

Hi Eric, this morning I wrote a clever two paragraph response to your problem only to have it escape to web never-never land when I hit send.

Too bad, it solved all your JW problems but due to my advanced age I can't remember a thing that I wrote. But I will try................

I love those little top hat intake covers, sort of a Howdy Mam tip-of-the-hat when in operation.... I had the same problem with one of my Mossie Enya's. Lot's of flooding and spits and starts but no sustained run throughout the NVA's range.

It took an A/F boil and some NVA alignment to fix it, now it's fine. It would seem that with all that flooding it would clean out the NVA but not always. After the boil I dumped the whole disassembled assembly into a pot of Simple Green and used a variety of brushes to to finish the cleaning process. But most importantly, I ran a fine wire through the needle valve and the central spray hole, then rinsed in clean HOT water and blew everything out with compressed air and reassembled with RemOil.

Then I took special care to ensure that the venturi's spray hole was positioned directly down the intake. I know there has been discussion here about that with some advocating an off center position, but on-center has always worked for me. Ensure your needle's tip in great condition.

The principles are all the same either JW or Enya, you need ignition, compression, intake "timing", and fuel in the proper quantity. If you have all of those your engine should run just fine. But you know all this.

Good luck with it. I haven't tried to run my top hat JW yet.

It looks like the larger hexagon should fit Eric, but if it's slipping with the possibility of causing more damage to a valuable engine I wouldn't push it. I have never seen a wrench like that so I don't know. I have removed those back plates before but don't know exactly how I did it, probably loose to begin with.

I enjoyed that link so much I saved it. Keep at it, should run.
