we have a new kazuma jaguar 500 cc, runs good for 15 to 20 minutes then develops an air lock in the fuel line, have replaced fuel lines, fuel filter and have cleaned the gas tank and we still have an air lock, any suggestions would be appreciated..thank you!

 

Welcome to the forum Norm W.

Sounds like the fuel tank might not be venting correctly...Try taking the gas cap off next time it dies and see if it starts...

 

thanks...we will try that next...will let you know if it works...first time on this forum, appreciate your time..

 

I just purchased 2 of this same Kazuma Jaguar 500. I am having the same issues. They have a locking gas cap. (I think it's non-vented) We are going to try an automotive vented cap. I don't know what else to try?
But, They must have sold many of these that worked fine?! I'm not sure what to do next?

 

we went to an atv mechanic today...he cut the gasket down, it is still stalling, he said if this does not work he will cut a slit in the tank directly and vent it that way...will keep you posted...anything you think we should know please advise...thanks!

 

Don't puncture the tank. Drill a hole in the top of the gas cap or find another method of venting the cap.

 

I just posted this in another thread... I had the same problem and it was the fuel switch. Get another filter or switch for a lawnmower or briggs motor from your ace,lowes,home depot,farm and fleet, Big R, harbor freight, or what ever. Just bypass the stock switch and put your own in. Ive had mine for a year and just got back on this forum today. Try it see if it works and let me know.

 

because the bolt that holds the bowl on the bottom of the switch would not stay tight...that did not solve the problem but once we changed the gas cap that resolved the problem...thanks for your suggestions

 

Glad to hear you got it figured out!!

 

Where did you find the fuel cap? Did you replace it with a stock cap? or aftermarket?
Thanks,
