even ga directly in cylander wont start... just checked stator and coil seems fine deffinately have spark though

[slimguy379]

changed the tming back to stock, was running +4. it will pop so at least thats a plus.

[slimguy379]

ended upbeing bad ground to the motor due to powdercoat ran a ground wire to the head and bom stats up buti believe its just burning off gas in the cylinder. i sti am not getting gas to the cylinder... still think the reeds might be the issue.

if its reeds you should be getting too much gas in the motor. make sure all the wires are good. green black orange ect make sure they didnt rub through or get pinched. make sure your floats arent sticking in the carbs also.

[slimguy379]

If I got it to run should wires still be a cause for no fuel? I'm not running tors

Brother, I would hold up and perform a leakdown test on that rebuild. You want to make sure you don't have any air leaks. If leakdown is good, then move on to why its not firing

[slimguy379]

No everything is fine... its now a carb issue

Check the screens in the tank, on the fuel shut off.  Also, make sure that your vent hose isn't blocked.  If the steering stem is full of water, and the end of the hose is in the water, the tank will not vent properly.

did a compression check, seems fine for a new build. NO clue how but i had lost spark again due to a ground. but re wired and tinkered with the carb to get full gas bam runs like a kitten. only thing is i need to hold on the throttle to keep her alive. spark plug just looks wet no black or white. i have a stock pilot but a 330 main, i did research on the jetting forum and from what i can tell thats apprriate. the air screws are 1 1/2 - 2 turns out. what could be my issue?

[slimguy379]

still is very hard to start need to kick and kick it ver until it finally gives, starts then i have to lay on the gas to maintain a continuious run

Are your slides in backwards?

[Calderon]

Pit a 320 main and go two turns on the air screws. That how I have mine and it start on first kick every time

You guys have the same mods? And how is a main affecting the start up?
