Bowl seems to fill up good...some people have suggested condenser or points...all were new 3 years agoIf it starts fine cold, with no choke, you could lean it out a bit.
If you drain the bowl does the fuel flow well or does it dump the contents and slow to a drip?
If there is an obstruction between the tank and bowl, you could get into a situation where it runs fine, then dies. Once the bowl fills back up again, you can repeat.
