steve i did squirt fuel in carb and no go what i do get it a back fire like the timing off. but not all the time could be 3rd or 4th craking after every back fire this thing has got good hot spark when cranking but does not seem to get a lot of fuel on the plug but after squirting fuel in the carb you think i get some thing but it just cranks a while before it back fires its going to blow the muffler right off this thing if i keep going like this.i did not get time tonight to look at it i will try a coil & plug and maybe a plug wire as a mechanic i am stumped never run in to this before.i know it need spark.fuel,compression,and timing at the right time.hell i even pulled the head to make sure the valves look good.
