Starting a gas engine...
 

Could you guys fill me into the basics of starting a gas engine? It's an older engine, not sure what kind. We're not sure of how to prime it, or how to correctly set the fuel mixture. Tho it's an older model, it's never been broken in. Thanks for your help.

Might wanna ask in the gas engine forum. They will probably give a little more help..

RE: Starting a gas engine...
 

Are there any markings on the engine

bluesilver30,
What brand and model of motor is it? Let us know that and we will definately do our best to help you get it started and running.

Is it truly gas fueled or nitro/glow fuel powered? People often say gas when they mean nitro.

thats what i was wondering.^^

Its likely the only way you are going to be able to get any help at all, There is far to many possibilities with what you have as you can see by the replys is if you could post a picture then that would go a long ways toward solving the mystery and getting some applicable help.

I checked the gas forums and his last 10 posts and he has not posted in the gas forum as was suggested. It appears he is working on a Beechcraft Bonanza but that's all I could find out

RE: Starting a gas engine...
 

Bubba,
He has been a member for almost 2 years also. But was the beechcraft even big enough for a gasser?

RE: Starting a gas engine...
 

I did a little research to see if I could tell what he might be flying and maybe made mention of the engine in another thread but I did not see anything. He makes no mention of who makes the beechcraft in anything I saw and has not answered the other posts in this thread but checking into all of his other posts shows that he sometimes does take a while to respond.

maybe it is his first glow. I figured he was talking about the Top flie one (maybe it was Great planes?)

RE: Starting a gas engine...
 

We need to wait for him to come back in and answer us

RE: Starting a gas engine...
 

Very true indeed..

RE: Starting a gas engine...
 

hey guys, sorry for the late response. we've been messing around with the plane all day. and thanks for all of the enthusiasm you guys are showing towards this project! anyway, it is an old real planes beechcraft bonanza that we are trying to fly. the motor is a super tigre 75. we've checked some of the startup procedures from the online manual, and that answered most of our questions...however we have a bit of a problem.

we tried starting the engine earlier, and it seemed to start up fine. however, we didn't break it in correctly. we had the high speed mixture needle much too lean, and we think we flooded the engine by fueling it up without disconecting the fuel line into the carb (extra fuel went right into the motor.) now, after cleaning up that mistake, we have a carb leak when we properly enrich the high throttle mixture needle for startup, and the engine hasnt started since we flooded the engine. any advice would be appreciated, and we'll make sure to get back to you guys sooner. thanks for your help.

btw: we removed the glow plug and did the procedures for clearing out a flood. hasnt helped yet.
p.s.s.: the glow plug is working properly, but we think the glow battery may be low. we're gonna charge it overnight and see if there is any change. the glow plug is getting pretty hot, but not orange or anything like that.

RE: Starting a gas engine...
 

Sounds like you found out the problem, it should glow pretty good. Hot is good but you should see it glowing, the brighter the better

I'd love to see any pics you have. I'm kinda fond of the full scale bonanza's

RE: Starting a gas engine...
 

This may be a dumb question but are you using GLOW fuel? I've seen that attempted with gas...... doesnt work to say the least:D

RE: Starting a gas engine...
 

yup, we are using the right gas.

and we will know by the morning if the glow starter is the problem. then it's just a matter of correctly breaking in the engine. any idea's about the carb leaking fuel when the mixture is set rich though?

i'll try to get some pictures for you bubbagates. however, we don't have a digital camera so it may take a while.

RE: Starting a gas engine...
 

89 or 83 octane?

JUST KIDDDING DON'T USE GASOLINE.


(But call it fuel instead of gas because they can easily be mixed up. Also call it a glow engine.. Then people will know exactly what your talking about:D:)

RE: Starting a gas engine...
 

You should be filling the tank THROUGH the carb line, not the vent line. Are you saying that you pulled the line off of the muffler, and fueld the tank up? Thats part of your problem right there--you don't have any fuel in the tank. You can't fill the fuel tank up that way, it's backwards. You need to disconnect the line from the carb (which should go to the clunk in the tank) and fill the tank up from that direction. Then, disconnect the line from the muffler and start pumping GLOW FUEL (into the line that was hooked up to the carb) until fuel just starts coming out of the line that was hooked up to the muffler.

RE: Starting a gas engine...
 

i didn't build the plane, a relative of my friend (who now owns the plane) did and gave it to him. so thats why im not too familiar with the plane. our fuel tank has a side port for filling, however when it fills it does go out the tube to the carb like you were saying. we just overfilled it without disconnecting that line.

we'll be starting it again with the charged glow starter after breakfast. the glow plug glowed brightly, so i think that will fix our problem. i'll fill you guys in shortly.

RE: Starting a gas engine...
 

alright, we tried starting it this morning. it started to kick over, but then quickly died and wouldnt start anymore when cranking it. the carb is leaking fuel still when the mixture is set rich. not sure why it won't start. any ideas? thanks

RE: Starting a gas engine...
 

Here is a pic of the fuel tank setup for you-

RE: Starting a gas engine...
 

The carb is leaking fuel where? where it seats in the throat? or out the top of the barrell? If it's out the top, then your tank is WAY too high, and fuel is just being siphoned into the carb way too fast. If it's in the throat, then you have an O ring problem--not seated, not tight, or bad. We need more information to help you out...

RE: Starting a gas engine...
 

2slow2matter, we think the tank may be too high. yesterday, when we had the engine started, we only had a bit of fuel in the tank. when we filled it to the top, thats when the problems started. we drained most of the fuel, except for a bit of it. we are going to try and start it like this, see how it goes. if that doesnt help, then we will check on a lose o-ring. right now, the fuel level is below the high speed needle, but when the tank is fuel, the level rests above the high speed needle. we'll get back to you.

oh, and thanks for the picture Broken.

RE: Starting a gas engine...
 

alright, we found why it wasnt starting. that will be taken care of soon. the problem we have now is the engine dieing when we accelerate past mid stick. the idle mixture seems fine, but when we get to the high speed range the engine dies. we're going to try and experiment with a few mixture settings, but could you guys shed some light on what this means? the engine dies fairly quickly when we accelerate it to a high level. thanks.
