George, email me if you want one, otherwise A Main has them in stock, just a matter of time until they get them up on their site.

Someone wanted the crankpin size, will try to get that measured today.

Steve, I think the standard 735 compares more closely to the Kangaroo in terms of power and performance. Both are very good engines. The 735RTC is a tuned engine with balanced crankshaft. It is identical to the 935RTC except for the number of ports in the sleeve. Either of the 735's will work well with a 2015 or similar pipe and medium or short header. I have installed a 735RTC sleeve set in my 935RTC engine, and used the 2052 pipe and at GLARCRC (which has a long straight) I have had no problems making 5 minute run time.

I have not had an issue with the carb, specifically with the screws coming loose, but I will keep an eye out.
