Finally,, fixed. Small peice of rust that I didn't see or clean of of the sparker was preventing flame. After I cleaned all again, works fine now. Thanks for everyone's input.
To answer the question on spiders. The additive to make propane "stink" supposely atracks the spider.
That is one of the reasons to clean the burner(s) each season
Every time I store my MH for a a couple of weeks or longer I have a similar problem with my fridge. The stove won't light either. I found a fix.
Open the valve on the tank.
Hold a barbecue lighter to a burner on the stove.
Open the valve for the burner. Eventually the stove will light.
Now the fridge will light.
