Help! pee wee variation.

Post  balsabasher2000 on Sun Jun 26, 2016 12:21 pm

A while back I posted about an Aztec two step which I built. I asked if 049s were too big, and that pee wees would be ideal but are hard to get compared to 049s. I decided 049 were too big and that I should wait for a second pee wee to come along. the pee wee I already have has the red anodized tank and a throtle sleeve. I'm currently debating buying an available pee wee going for the right kind of money here in the uk. this engine has a non-anodised tank and has a mesh like sleeve around the exhaust ports. it comes with the box and is in good condition by the looks of it.
My question is, if i removed the throtle sleeve and mesh, other than the fuel tank would these engins be the same and be suitable for use in a twin?

Well, I'm no expert, but IMHO, I would say Yes. The 020 engines used the same cylinder piston. So whether you have a ground cylinder or one with the mesh they both should be the same stroke and bore. They just won't be identical twins. Eyebrows

Bench tach them. Realistically they should produce similar numbers on the same prop (yes, the same prop, swap between the two and make several runs on each)

Next using two identical props have both engines on the test stand(s?) and see if you can get them to sing in tune with each other.

If the pair will do this easily, then they are well matched and will hopefully do what you want of them.

Thanks for the replies, just recieved thin pee wee, its almoast new with the only sign of tarnishing on the top face of the piston. like all these small engines, its a jewel. Very Happy
I'll let you all know how the maiden goes when I get the props. i'm expecting one heck of a buzz. Shocked
