Hi al
 
	Got a TY175 recently and nice looking bike. Starts OK but will only run for a few minutes then bogs down after riding for a few minutes.   When you let the clutch out when pulling away, doesn't want to go, bogs down and have to give it a lot of revs, but then eventually it dies and won't start again then.  
 
	Any ideas?   I think carb related as repalced spark plug and air filter is clean. 
 
	 
 
	Many thanks!
