It's a 5 month old 1915 Dual port build that has been ran VERY little. It has a "Dual" Weber carb, bigger heads, and a blower cam, from what I was told. I CAN NOT get this thing to run correctly. I had the carb gone through by an "old school" hot rodder. He said it was filthy, and didn't say anything about it being cracked (which has been mentioned as a possibility). What Jets should be in this thing? How does the timing work on these? Here are pics of them... should they just slide apart? Seems like they need a dab of lock tight to stay in place??
jus blowing through the jets is probably not enough, u will need to get a complete rebuild kit with float and accelerator pump and probably be a good idea to let it soak for a day or so and blow thru all the passages and jets and allow time to dry before reassembly.. i dunno exactly what degree timing should be, more specs on the motor (cam #, head size and compression play a factor in this..) but a good way to get close with out knowing all specs is to get it cranked and running.. loosen the dist jus enough that it will turn. get the revs around 2500 and twist the dist.. clockwise advances and counter clockwise retards, find that sweet spot and tighten it down. the sound of the motor will tell you what it does and doesnt like, but careful not to jus crank on the dist as it doesnt take much turn to make a change.. hope this helps
