got fire, no gas

Im bringing back to life my dormant A4. She is turning over. ive replaced points, plugs, condenser and coil. getting a nice bright blue flame but it appears no gas. i believe the next step is to get a carb. kit. does anyone know who makes a good one, and if this is a logical next step. i hope it is, 'cause i already pulled the thing off. lol.

also thought compression was a bit low in 1, so put some marvel in each plug hole to rest while i get this carb deal worked out.

any suggestions would be appreciated.

thanks
Quinn

got fire no gas-a4

just replaced coil, points plugs condenser on my a4. getting a bright blue spark, and there is gas through the fuel line, but while she turns over she wont start. is the next logical step the carburetor? if so can anyone recommend a good kit, and how difficult is that to put in?

thanks much

Quinn

I would go with the service manual from Moyer Marine as it covers everything in a DIY fashion rather than assume your allready and expert

I dealt with cleaning the carb on our A4 last spring.
First you have to determine if you have the early or late model carb. This will dictate what shape gasket you will need when putting it back together.
It is likely that the float valve may be stuck in the closed position which would not allow enough fuel into the carb. You may also likely have clogged jets which would also restrict the fuel flow.
A good cleaning with carb cleaner may be all you need to get the engine to turn over. I'd recommend removing it from the engine (2 bolts, throttle & choke controls) and working on it in your garage or workshop.
Check this page at Moyer Marines online catalog for the various carb pars you may need: Moyer Marine Online Store
You may want to search the forums at Moyer Marine as there is a lot of info on the carb over there: Moyer Marine Atomic 4 Community - Powered by vBulletin
Hopefully your fuel pump is working and it is fairly easy to check this out by removing the fuel connection to the carb and see if fuel comes out when you crank the engine.
Good luck.

Assuming that it was working before you started the tune-up, if you start mucking with the carb, you are likely to introduce a fuel/air mixture problem too.

Having spark and fuel/air in the cylinder only is solving part of the problem... Because you've replaced Coil, Points, Plugs and Condenser, I would suspect that you may have introduced a TIMING problem.

Check the timing with a timing light, and the point installation with a dwell meter.

There are no timing marks on and A4 YA just set the points when #1 is on TDC and wing it

It kind of like a big lawmower motor and the manual tells you to set the timing under load till it feels good

Hit the Carb bowl with the handle of a plastic screwdriver handle. Stuck Carib float. Always works the guy 2 slips down from me. If that doesn't work, then listen to Paul. No on second thought, just listen to Paul.

Thanks Tommays I don't have an A4 (and never will). I still think that you should work on the timing BEFORE mucking with the carb.

Get and follow the Moyer manual as Tommays recommends. It isn't hard, especially if you know someone over fifty who worked on carbs in his youth. The high speed jet is fixed so it doesn't need to be set, just cleaned. If the A4 was dormant with gas in the carb that is probably the problem.

The fuel pump and carb can be in perfect working order, and you can have fuel starvation problems. You need to have a solid column of fuel from the tank to the carb in order to maintain the syphoning effect. May want to look into putting a priming bulb between the tank and your Racor. Charge the line with fuel, and see what happens.
