first off i live in the mountains so im dealing with the altitude. second its brand new. third
i took it out htis morning with factory needle setings and it toook a while to start but it started was a little slugish and motor died when close to idle. so i set the idle screw up and tried the pull start it was hydro locked and i loosened glow plug put it back on tight now almost impossible to start. leaks right from glow plug so i tightened seem to stop then gets hydro locked again both trying to start in the water and dry start same problem any help would be great

another thing is my dubro glo-plug ignitor supposed to get hot or should i be able to just stick it on and pull the pull start and it should fire right up? i also just took the glo-plug out and waited an hour or so put it in and it fires for a bout 1 to 2 seconds and stops then i have to take plu out and wait again. sound like its flooding but i cant seem to stop that. maybe i have to play with the needles a little more

Sounds like your gonna have to play with the needle setting.
To get rid of the hydro lock faster just undo the fuel feed and glow plug and pull the starter a couple of times then plug everything back in so you don't have to wait between needle settings

ya ill try that and is there a way to tell if im running it to lean becasue i cant even run it for 1-2 minutes to check the high speed needle settings.?

you can tell if the engine is running to lean because it will eather do one of 3 things....first just die, second squeal like a lil pigy and there will be NO smoke comming out of the exaust, third the engine will dead stop an you will hear eather a crack, boom, or pop......non of these are good.....i've busted a few engines and let me tell ya you dont want to do it...you dont want to lean the engine out right away you need to put about 3 to 4 gas tanks of fuel through it to make sure its broken in an lubricated....these moters are dead stiff once they get out of the facotry. read the engine manual...i believe its the dynamite .15.....i had that engine in my first boat...an it sucked but once i broke it in it was alright.....when it vapor locks take the plug out an punch the fuel line an pull the pullstart to get all the fuel out of the piston. then lean out the highspeed about a quarter of a tern.....its a very very tuchy needle valve.....wait till you get into the real stuff an have a third chanel on your boat so u can tune out the engine while its in the water an going....its a life saver an it gets going much faster...Good luck.

awesome thx and ill report back soon on progress

well i richened it up and had a few good seconds of running then died but anyway now the pull start is stuck and its not the hydro lock this time.lol[&o].so im in the process of takin it apart and well c what happenes from then

im sorry guys i dont even want to admit this but ignore the last post i had a big ass brain fat while i put the boat over a towel hehe (incuding the prop) lol

k heres my update starts up almost every time now that i richened up the low and high.last a bit longer running but when i take glow plug starter off engine dies. glow plug looks fine no silverish color or brown. o and one more thing when it starts it has a tendency to pull the pull start hard back to the case and die. thanks again guys. its getting closer!!

It sounds like you are too rich. Change the glow plug. Also when the engine gets to the point of back fireing, you have too much fuel in the crankcase and the exhaust pipe. Pull the plug, hold it upside down and pull the crank rope a few times. Then roll the boat around to drain the fuel out of the pipe. re-install the plug and try it again. What % of nitro are you running?

its the blue thunder 20% nitrous. if im running to rich why is it hydro locking all the time?

Hey dude...I had the same problem once with a aircaft engine...an OS .60 2 stroke if I remember. Anyway I droped from 20% to 10% nitro and it worked liked a champ. It did not like the 20% at all. Hope this helps! [sm=biggrin.gif]

well i leaned it up a crap load almost all the way ran ya .... it ran lol i slowley backed the needle up and its working great now thanks everyone!!!!

You will need to run it on the rich side till it's broke in...a couple tanks of fuel should be enough. It needs the extra lubrication while parts seat. Glad ya got it fired up!

[Hey hurleyfevr,
Hope you enjoy your boat, they are fun. I have started doing one thing that may help. I have a glow plug wrench. A "T" bar thing. This makes it quick and easy to loosen glow plug 1/2 turn before I start it, and once going tighten back. The whole world looks brighter this way. It easy to pull. If it is hot and I just come in for refill loosening is not necessary. The best time is if you flip and are trying to get it going again. Priming with fuel lowers water content, easy pulling makes it quick. Priming has helped me many times to get the thing started, particularly first time of the day.

As far as air/gas mixtures, the outside adjustment is the high speed here at 35' above sea level I go out to about four turns and adjust from there. If it quits it is too lean, keep enriching till it doesn't quit. If you can do 90 degree turns and not bounce your not at best speed. I run about half throttle and rev from there but no low idle. This works fine, there is no reason to go any slower. The hard to reach low idle or horizontal adjustment is tougher. I got max speed and consistency, perfection is for others. Once a standard is set where current settings are working and understood then I think adjusting the idle an 1/8 or so at a time till the idle is low enough to your taste is possible but even the direction must be tested.

If you wreck your boat and want to sell what is left I may be interested, spare parts are sometimes hard to get. We race regularly and run into each other!

ok ive been lazy and havent been out in a while maybe today but sure ill contact u if i crash but i dought that ill probobly end up screwin it up another way lol.
later
