Thanks Zipper06.
Forgot to mention, 8 gal cell in trunk, electric pump feeding 2 gallon resevoir with old Holley float bowl for regulating, -12 from bottom of res to Enderle filter and then to pump. Pump is lower than res but higher than filter by about two inches.
The hat is a bugcatcher, purchased new last year. Has maybe 4 - 5 hours run time on it. I guess it still could be the shaft bores but reading between the lines here it sounds like I should be looking for an air leak somewhere.
Once I get it lit off again and start on the tune I will smoke test and see what there is to see.
Thanks
