Engine Priming
 
1 Attachment(s)
Hey All

Well, I'm finally breakin in the Torpeda. When I'm priming the engine (finger over muffler) it takes forever to get the fuel through the line. I was thinking of using the rubber bulb from a baby asperator (anyone with kids probably know what this is, basicly used to suck boogers from babies noses). The rubber bulb fits perfectly on the muffler and one squeeze is the perfect amount to get the fuel to the engine. This can't do any damage can it?

Thanks Eh!

Will it damage? If ya get boogers in the fuel line!! hahaha no seriously I really think thats quite inventive! But having said that, you really shouldn;t need to prime that way. The pull start should be sufficient enough. How many tugs does it take to get the fuel upto the inlet nipple? (anyone familar with woman should know what that is!..haha)

It can take a good couple of tugs. Now when you prime you put your finger over exhaust stinger to make a seal. If you're not doing that, there's your problem I'd say. If you are doing that It may be that there is a leak somewhere in fuel or pressure line.

LMFAO

Yup, priming with finger on exhaust takes dozens of pulls (same as my wife) I can't find any leaks, and once it starts up, it runs fine (same as my wife)
If I had a leak in the line, wouldn't it have a problem staying running?

hahaha good to see some humour on this forum! far too many serious heads on here. if there was a leak its likely to cause all sort of idling/running problems. It will also cause the engine to run lean & overheat too.

How tugs of the cord. Full tugs? maybe takes six? When you do it, you should see the fuel move up the line each tug. It will depend on how long the fuel line is too. I ususally replace the factory tubing for better tubing from the shops. Also check the joints on that filter of yours. There is more chance of a leak in the filter, especially if its not screwed up tight. Check the o-ring in the filter is intact.

I had this same problem before, what i noticed was that after about 20 pulls i still didn't get any fuel into the fuel line. I had to resort to dripping fuel directly into the carb.
The engine would start and then die soon after.
Turned out the high speed needle was closed in too much i had to open it in increments of 1/8 turns until i had it about 3/4 turn open. Try this giving the pull start
a pull after every 1/8 turn opening, eventually the fuel came up quite easily!!

Ya, I was doing little girl pulls on the starter. I think I'm just nervous about ripping it out, but the bulb is working perfectly (takes about 2 sec). When I'm done running the engine, I squeeze the bulb, put it back on the muffler (after it cools), and suck the excess fuel from the engine and tubing back into the tank. I do need to change the tubing though, what color is easiest to see the fuel through?

You shouldn't need the asperator bulb. Even though it's working well for you, there's a problem somewhere. I actually have a fuel filter with a built in primer bulb. It's the *****. Don't go shoving that thing back in your kids nose now!
As far as the color of fuel line, the ONLY flavor you'll be able to see through is clear, which actually has a blueish hue to it.

Try charlieboy's idea about opening up the needle a bit. It makes complete sense.
