Vinyl? Really? Stunning! Can't wait to get a glimpse of the Sweet Vee in person.

Yes, he will be racing EF1 with that Proud Bird. This will be his 3rd year racing EF1. I have another Proud Bird, new in box, .... just in case! Hello Bob. Maybe get that backup Proud Bird out of the box and assembled now rather than later and bring both with you to the races...just in case. :wink:...

SA-weet!

It's the height of the sleeve ports in relationship with the ports on the case that need to be properly aligned. If you raise the sleeve to .203 it doesn't do much good if you can't raise the exhaust manifold port in the case. Likewise with the intake and transfer ports. This sounds simple but ther...

Cool stuff Ray.

Nothing to contribute, just letting you know I'm paying attention and thanks!

Say, I ordered some various spare parts for my Nelson (package received - thanks Mike!). The bag containing the head is labeled .8014 as shown. This is the diameter of the button (?) portion of the head that protrudes into the sleeve. Why is this dimension significant? Is it to be matched with a sle...

I don't think that needling the engine, typical maintenance, reading glow plugs and understanding deck height and piston/head clearance need to be black art. When I got my engine it came in a bag. If there were more guys like you around, pylon racing -- or at least Q40 -- might be more accessible. T...

Ordered some parts today from mike. We spoke at length about the front bearing tolerance. Mike tries very hard to keep the motors as exact as posdible. But, and I don't blame him, he won't comment an anything about the do it your self ers. At APM they press all the cranks in. An alternative to maki...

Thanks for the tip Dan and for the words of caution Tom. The thought of gaining any performance advantage never even occurred to me, but sure thing; rules are rules. I'd just like my engine to last as long as whatever it's supposed to. And I hate to think I'd be contributing to another new guy like ...

Hey, it worked! Just like Ray said!

Thanks Ray!

Well, this brings up a whole ‘nother topic; How do you care for/clean up an engine? And what procedure for just after a weekend’s racing, and after the season for long-term storage for a couple of months? After Wichita I saw Duane Hulen completely tear down his engine and was cleaning it up/lubing i...

Hmm, so then, this sounds like a procedure you would do only when replacing parts (such as bearings or the crank) - the crank doesn't just drop out like a regular 2-stroke glow engine. I was simply breaking down my engine to clean and oil it up for storage. Crank removal shouldn't be necessary in th...

Breaking down my engine to clean out any residual glow fuel, have a look-see and lube it up - piston and liner look fantastic. Any light (and I mean VERY light) browning/coloring washed right off with some brake cleaner and a paper towel. But say, how do you get the crankshaft out of a Nelson ? A fe...

Couple of flights on my Sweet Vee again today. Wasn't expecting to be flying these things this time of year, but another beautiful weekend here in the Midwest - my wife launched again for me too! :mrgreen: My setup is now .190/.019. Still running the gallon of fuel with castor added. Prop is 7.4 x 7...

Another question about shimming; Once you know your engine setup without shims, could you/do you then just do the math and add/subtract shims to get the desired setup without re measuring? For example, I don't have a depth micrometer (yet) and haven't measured my engine myself (yet). But, again, acc...
