Thanks to all of you keeping us so busy the last few months we have to make a change to our Phone hours.

We can be reached via Phone Mon-Fri 10:00am to 3:00pm Pacific time. 

The Shop is open and we are working normal hours but we need those extra hours to catch up on Engine work, Carb rebuilding, and shipping. 

If you call before or after the hours of 10:00am - 3:00pm leave us a detailed  message and we will call you back. 
You can always shoot us an email at 
Obviously you are seeing this on the website so much of what you may need will be here...

Thanks for understanding and for all the support that is keeping us so busy....
