Two Stroke Racelab

Prof. Gordon P. Blair is the author of the most challenging books regarding two strokes engines. He is the man behind the modern two stroke engine and the pioneer of software programs on engine development.  His books and SAE papers regarding flow & gas dynamics are outstanding though a little bit complicated for my messy maths. His work is very inspiring and toward developing new ideas rather than just giving answers on several topics.  Prof. Gordon P. Blair died on October 21st 2010 after battling cancer for several years though his inspiring work should stay apropos for many years to come.  Biography (taken from this link ): Gordon Purves Blair was born in Larne Co Antrim in 1937 and educated at Larne Grammar School. He then went to Queen's University in Belfast to study Mechanical Engineering, where he obtained a BSc degree in 1959, a PhD in 1962 and a DSc in 1978 - this latter award is a "higher doctorate" awarded in recognition of a substantial and sus...

I fitted a pair of power jets on Lectron carbs and here are a few pics of the installation. The powerjet should be positioned on the top of the carb and as close as possible to the slide. Any position close to the top of the carb will do but do not exceed 90 degrees from top center. After you have determined a suitable spot, use a center punch and then drill a 4mm hole. Then use a M5x08mm tap and form a screw thread. And that's all about it. Screw the power jet with a smear of Loctite thread glue and you are done. If your carb does not have a provision for a power jet at all, you may have to repeat the steps for a second M5 thread on the carb bowl as well. Many people don't really bother making a thread and only make the hole and permanently fit the power jet with epoxy glue. I have gone this route several times in the past and never had an issue, so keep that in mind as well. The end result should look similar to this... These carbs have a bore diameter of 38mm and ...

From  Dawn... ...till Dusk.

Being busy fabricating quite a few power jet kits lately, as there is a lot of interest from many two stroke junkies around the world. Thanks everyone for trusting my products-services and please remember that I always welcome pics with the final product assembled.
