it's a Marvel Schebler TSX 813, I put a new shutoff valve on the gas tank, put a new glass sediment bowl on it and put a new rubber fuel line from the gas tank to the carburetor......when I start it up I now have to use a shot or two of starting fluid, an to KEEP it running I have to keep shooting the starting fluid to it, it's like no fuel is getting into the carburetor.....at the very top of the glass sediment bowl there is a bit of an air pocket and, I CAN see a bubble or two ?........any idea why an how to get rid of it ?....also, I pulled fuel cap on the tank to add more gasoline an I got a "whoooosh" like there was a good size vacuum built up,.....I read another thread awhile back, somebody said THEY were having trouble keeping the engine running, like it was starving for fuel, he said there was no vent hole in the gas cap,....same with mine, so I drilled a hole in the very top, ...............thanks in advance for any and all help,
Denny
