Take a hair dryer or a heat gun and heat the engine up, this will aleviate some of the pinch and will stop this from happening. I had the same problem with my .18CVR and this solved the problem. You only have to do this for the first 4 or 5 tanks after those tanks it should be good to go. You can also put some ARO in the engine to help lubericate the engine. You only have to warm the engine till it gets good and warm, warm enough that you can hold the heat sink but not for more then a second or to, that how I tell when it's good to go and try.

Get back to us on how things go.
