I put a inline fuel filter in so I could monitor fuel flow and after starting it there’s no fuel in the filter it will set on the stand and idol I adjusted low and high and it runs smoothly it will rev up wot but when on the track under load it will die with any movement of the throttle I’m new to these carbs so just trying to figure out how they work properly maybe I should just buy a mikuni and be done with tillotson everyone I race with runs the mikuni and has no issues but they run stock gas tanks with no fuel pump
The carb is sold with drill pattern not full size, so builder can customize pattern for particular application.
If this is a new carb, for that model number, the work has not been completed.
EC offers a version with the drill patterns set up reasonably close for your particular application.
Of course, these are more money.
Long story short, if you buy the cheap version, you sometimes get what you pay for.
Sometimes, a used version from a working setup is a good buy.
so Next question is the engine was a alcohol engine it came with a tillotson alky carb is it possible to put the plates off the gas carb on the alky carb body both are hL series carbs seeing how that carb was the original carb for the engine btw you’ve been great with the answers to my questions I’m starting to understand a lot now I messed up buying a builders carb you live and lean
The drill pattern is under the welch plug in the body of the carb -- the fuel holes are drilled directly into the venturi area of the carb body and should not be modified by anyone without a LOT of experience working with these carbs.
No, there's nothing you can do with that alky carb (except run it on alky) at this point.
Yes, you'd do better with a Mikuni, they're pretty much plug-n-play.
If you want to run the Tilly, send the 304WX back to EC and have them re-drill it for your application - they will do a fine job on it for you (at add'l expense.)
