If the fuel has been sitting for more than 3 months, then sure I would start there. Also you mite be looking into a carb overhaul! Keep us posted!

I was thinking that or may be intake or air leak on carbs what do you think I replaced all gas hoses and maybe have an air leak somewhere since it seems to run at half thottle fine

Re: engine problems

Well the fact is it should run good no matter what position the throttle is in. Sounds like the low idle curcit is plugged up. Sounds like carb overhaul is in store. Post back and tell us what you find!
