Yea, that was my first thought when I purchased the needle valve assembly but by the book, it is plumbed correctly. I guess I'll have to pull the whole motor apart and check the bearings Thanks!

Hey Dan, Lots of good info in your post....Thanks! You speak of "opening the head bubble". Does this mean milling out the underside of the head button where the plug comes into the cylinder? Can this be done on a drill press or does it require a much more precise method? The fuel system...

Yea, the hull is better suited for a .67 but since I had the .45 motor, I figured I'd give it a try. I have another of the same hull that I am putting a gas motor in.

I'm not sure, the needle assembly is for a .46 plane motor.....I figured it would work. I may end up getting another remote needle.

Ok, lots of replies, thanks! -Tom, I'm not sure the brand of pipes I have run but here are a couple pics. The stinger I.D. of the longer pipe is .37" and .41" on the shorter pipe. The motor really liked the shorter pipe with the prather 240 but again, blew plugs and leaned on the top end...

Looking for a Dumas Skater cat hull

Howdy All, Wondering if anyone can explain the process for determining correct pipe length for my OS .46. Here is the pipe I'm tentatively using...I am not sure of the make, it does have a chamber inside....(quiet pipe?) The pipe is currently just over 16" long. Thanks!
