Jim Wilson on multiple occasions during testing used to actually show me the effects of load and the ability to burn nitro. On as extremely well tuned boat he would reduce the load and results were similar to what you are experiencing. The boat would pull hard out of the corners. Come up to rpm...
Well then if you guys want to pay for shipping and $5 for the cap they are yours. PM info if you are interested. I have lots of new and used parts for these engines so now's the time to ask
Hi Greg
I don't know the history of CMB but I have been running both the silver and black case RS for qiute some time. Pretty sure Stu still has parts for these.
