Default Re: Pulling trailer against the wind overheating??

You're very welcome borntofli!

Richening the mix will increase lubrication. That will help when you're hauling loads.

That rush is certainly caused by a leak. At the head, exhaust manifold, or intake. How about a project? This one will take a few hours time but you'll be sure that you have good seals, and a bump in power. I'm talking port matching the exhaust pipe and intake tube. Follow it up with new gaskets and a bit of copper goo on everything. In the end you will have a nice airtight engine.

If after all the good advice given in this thread you still have heat issues, you might need to try a 44 tooth sprocket.
