i would rather not tamper with the engines other than the normal jet adjustments. Why both? I Don't understand why? Pennzoil's engine is just fine but the later Pepsi engine is the one with the issue. As it does not perform as would be expected then that shoud be reason enough to send it back for testing. Thanks for all your inputs Guys.
I will email Peter and suggest that the only engine needing checking is the Pepsi and see what he says.
