Ignition timing ?
Everything was going along just fine today I had a successful maiden voyage, then the next short ride was a flop. I got her home it will idle fine but has no power at all. I put a new fuel filter but it is still the same I am sure the timing is off and was wondering what the timing for a 402 should be any other help would be great! The truck is all stock . I here that those original carbs are no good but it seemed fine up until today

Re: Ignition timing ?
If it helps at all if it sits for a few minutes and I start it , it runs decent until I start driving then I lose power, starting to think I have a carb problem idk

Re: Ignition timing ?
A new filter?? An inline type or the one in the carb inlet.

Re: Ignition timing ?
sounds like it's running on the fuel in the bowl when you start up then as you drive, the fuel does
 n't keep up with the demand-check all filters-check fuel pump-is the tank getting vented? How does the fuel line look from the tank to the carb-any flat spots or crimped hoses or lines?

Re: Ignition timing ?
The filter is the one in the carb no in line filter the fuel pump is brand new all the lines look good no kinks . What is the vent issue my 68 only has one line coming from the tank so I never thought of that what do I look for? In the meantime cause I can never sit still I took the carb all apart and found a lot of junk in the bowl this was my first go at something like that but I figured the only thing I would want in the bowl was just clean fuel?

Re: Ignition timing ?
Is the filter in correctly. IIRC the hole in the filter body is towards the fuel pump. and there should be a spring in there too. Sounds like it's running out of fuel.

Re: Ignition timing ?
You need to put an inline filter between the tank & pump. That trash can get in the fuel pump vales & cause a loss of pressure.
