RE: 3W 100 quits in Knife Edge

Unfortunately, there is no sweet spot until that fuel is prevented from pooling in the induction housing. What's happening is that by minimizing the effects of excess fuel hitting the heads when...

RE: 3W 100 quits in Knife Edge

Dave, I'll see if I can fast track you one of these boots as I'm sure it will turn your engine around. As far as your mate's similar machine goes, there must be something slightly different in the...

RE: 3W 100 quits in Knife Edge

30 flights - That's good enough QA for me! I'm gonna make a small batch based on the proto to pass around. Probably take a month given work and family commitments.

RE: 3W 100 quits in Knife Edge

Yes, one from composite materials is a good idea. Perhaps an injection moulded fuel/heat tolerant compound. Still, so far so good with the prototype. 20 flights now. One nice feature of the...

RE: 3W 100 quits in Knife Edge

I managed my flight tests today. The verdict is in. The engine has been transformed!

I performed 5 ten minute flights during which I threw the plane around every which way, including long...

RE: 3W 100 quits in Knife Edge

The prototype was made by first making a silicone cast of the crank case. I just put some type of thin plastic sheild (cling wrap) inside the crank/reed cage housing to stop any junk falling into...

I'll reply properly in the next few days, flat out at work at the moment.

RE: 3W 100 quits in Knife Edge

WE HAVE A WINNER!!!!!

The fuel puddle theory is a fact - the boot WORKS!!

I reckon there is some strange turbulence around the reed cage with eddies and weirdo airflow where fuel mist is...

RE: 3W 100 quits in Knife Edge

The reed valve assembly is quite different in my 1 month old 3w106. See pics attached.

In the first two pics you can see the reed/crank housing on my 3w85 filled with silicon as the first step...

RE: 3W 100 quits in Knife Edge

Just a quick addition. I discovered a convincing amount of residual fuel/oil around the bottom of the read carrier (flange area facing the crank). I am now in the process of moulding up a silicon...

RE: 3W 100 quits in Knife Edge

I have my findings with the new reeds/block. It made no difference at all! I started my plane normally with the cowl off and once warm I ran it up and tuned the carb for good fourstroking-free run,...

RE: 3W 100 quits in Knife Edge

Only just got the carb reeds/carrier and will ground test the plane tomorrow morning. The reeds sit nice and flat on the carrier so I hope for a good result. If not, drilling a tiny scavange hole...

RE: 3W 100 quits in Knife Edge

Hey dudes, I've read this thread with great interest as my 3W85 displays the exact same symptoms. I have ruled out any issue with the carb itself as I have swapped it with a brand new one from my...
