P.A.W. .09 Diesel Lazy Bee Installation

Nitro's evil influence continues as my second P.A.W. Diesel arrives from Mr. Eric Clutton and gets put through it's break-in paces. After threatening to remove the P.A.W. .06 diesel from my faithful Lazy Bee and reinstalling my equally faithful O.S. .10, I was suddenly seized by the idea of upping the engine size with a larger diesel. It came in today, and I had to hustle through my afterwork stuff to get some time to put it on a stand.

These suckers surely are a different breed of cat, and I've got to admit that I really like their low buzz on a close fly-by. It's fairly cool out tonight, and I DID have to heat the head a bit with a heat gun to get it to finally pop, but it finally settled into a good run in spite of my still-amateurish attempts to reconcile it's mixture and compression adjustments.

I ran out of energy and daylight at about the same time, so it'll get bolted to the Bee later. Videos to follow...

PAW engines are very straight forward to use, for the 09 mkII a 9x4 or 8x6 prop is a good match and just take your time running in the engine, it will improve gradually for quite some time.

The carb is a little crude (and lean at low revs), and you can get a better idle by using an Enya 09 carb (direct drop in and gives you an adjustable airbleed). The stock carb should still give you an idle around 3500rpm though. Here is one off mine (an mkII) in a thunder tiger scooter;

The Lazy Bee gets it's forth or fifth power-plant switch in it's 18 years of cruising Missouri Skies. I spent this evening extending the Bee's throttle cable, modifying a Hayes engine mount for the P.A.W. .09, and making up a new mount for it's film canister fuel tank.

Now, we just need another calm evening, so that the Bee can try out it's new diesel engine.

There seems to be a very large gap between the crankcase and prop driver, is it on properly?
If the gap is too large the crankpin will hit the backplate at low revs. You might want to put a few shims behind the propdriver before you run the engine.
