Moderator, thanks for switching this to the "tech" section. I had thoughts of posting here first but went to "Off topic" because it being a Motorhome.

Thanks much for all the inputs, some of the recomendations I've tried, others are good suggestions to try.

I thought I had it today, I triple checked the timing. I was using a yellow dot someone put on the damper. After I pulled the spark plugs I used the stick in the plug hole to verify TDC and compared with rotor position (using yellow dot). The disto was a few degrees off, So I set the damper notch to 0* TDC and slipped the disto out a little and tweeked the rotor to fire at #1 TDC. Then set at 8deg BTDC.

With the timing correct I was able to adjust the fast idle to stop the gas from squirting in the throat (passenger side is the Primary or secondary?).

Drove it around a little and felt fine until it warmed up. Then the missing and sputtering started up and it stalls at idle. At least I got the idle down from screaming fast.

So it continues. I need to get my tach back from my son though.

Thanks again for the inputs.
