Thanks Larry Howell Sun, 22 Nov 2009 00:15:03 GMT Lance http://groups.yahoo.com/group/AirVW/message/14153 http://groups.yahoo.com/group/AirVW/message/14153 Thanks you guys. Adjusted the timing, remembered to open the fuel shut-off valve, and it started right up. Ran nicely a few minutes around 1000 rpm.

I like SS valves. They're not all the same. Running in an aircraft engine we can generally get along with those near the lower end of the price scale.

However valve guide wear is even a bigger problem.

This relates to the question of whether the pilot is flying over land or water. I would not normally expect a Tue, 17 Nov 2009 01:43:49 GMT Joerg M.

Would it be wise to use other valves. Stainless, etc. Dan R.

But for the gp, I would need to know the cam specs to get it right. GP may be using a stock cam, which is Mon, 16 Nov 2009 16:48:49 GMT noel http://groups.yahoo.com/group/AirVW/message/14144 http://groups.yahoo.com/group/AirVW/message/14144 ... Hello Lance, I would agree with the figure of 28deg. BTDC. That is what my engine on a VP-1 is set to and it starts easily and runs well.

But I see you have also renumbered the cylinders so it is the same, Sun, 15 Nov 2009 21:53:19 GMT gil devault http://groups.yahoo.com/group/AirVW/message/14140 http://groups.yahoo.com/group/AirVW/message/14140 Lance, I'm no expert on VW timing, but my manual calls for different firing order if you have a mag or a distributor. The firing order for a mag is1234 and
