Fuel tank vacuum stalling Iseki Landhope

[terraformer]

First post here.

I have newly purchased my second Iseki, a TU200 Landhope. 3 cylinder. My first is a G192. I was impressed with the reliability of the old girl. Looked until I found one with 4wd and a front end loader.

I was using my "new" one yesterday and after an hour of running it chugged to a stop. I investigated and found that the fuel tank had a big vacuum on it. I guess I could vent the tank with a fitting but presume that that has been done by the manufacturer. Is there a vent line that needs to be cleaned? I was able to get it going and noted that after every 20 minutes it had redeveloped the vacuum. However I didn't have another stall out.

Thanks for any help.

Is there a vent built in to the cap ?, maybe it's plugged.

It may be the wrong cap. My TA210 cap is loose fitting. It has a hard paper type gasket.

Yes it was an aftermarket cap.
Stamped Eaton on the inside. I took out the rubber seal and notched it at the tiny vent hole. Thanks for the help guys.
