I have never sealed any of my Werks motors and have not had any problems.

i need help......

I have a B5 that ive had since last summer but it has about 2 gallons on it is all. I have a werks 2057 pipe running werks plug.

We had a race last night and for some stupid reason after i would run it and shut it off via the flywheel the next time id try to restart it it would be so flooded the fuel would run out of the pipe.

BUT......once we would get it running it would run perfect. idle for a minute without dieing be snappy as hell too. It almost acts like after you kill the engine it is syphoning the fuel from the tank as it sits there. I didnt have this problem until yesterday.

I changed everything i could think of, tank, line...ect.

anyone else had this problem?

i dont think its in the tuning because the motor runs perfect after you get it going. Just after it sits for a few hours its so flooded that when you touch the ignitor to the plug you can hear the fuel ignite thru the exhaust.

only way we could get it running was to leave the ignitor on it and hold the throttle wide open for 30+ seconds........

is it the pipe? carb?

To me that sounds like some type of pressure related issue i.e. when the tank cools down and shrinks that it is not venting and instead forcing fuel into the carb. I'd start by checking the everything pressure related i.e. pressure line for holes, pressure nipple on pipe for blockage, any filters that you might be running in-line with the pressure nipple etc. etc.

About the glow plug shortage;

Since all these engine brands are produced at the LM factory, my guess is that the Sirio turbo buggy 5/6 plug = Orion turbo buggy 5/6 plug = Werks turbo buggy 5/6 plug.

Afaik they are identical (even the packaging is the same except for the logo's) and are also produced by the LM factory.

In the process of breaking mine in, and no you don't have to seal it.. the engine fired right up and almost ready for race tune..

I posted this on the B6 thread and wanted to put the info up on this thread also!

I'm happy to say that the first product that we are rolling out are our new "Race Prep" B5 & B6 engines! This will initialy be an exclusive product available through A-main Hobbies only here in the US. Each engine will be individually disassembled and inspected, then run for 500cc of Werks "Race Blend" fuel on a break in bench then completely disassembled, inspected, cleaned, lubed and then re-assembled prior to shipping! It's a lot of work lol! "Race Prep" B5 & B6's are already listed on A-mains web site and available for pre-order! We will be shipping them the initial batch within 2 weeks!

you mean these?

ok. i checked everything in that area. all i have is the tank pressure line running to the pipe. no filters. everything was free flowing. any other suggestions?

Sounds like you have a clog in the pressure nipple on your pipe. Have you tried blowing back down your pressure line towards your pipe?

yep. everything was flowing freely.

Then I hate to say it but it sounds like you have some type of tank issue going on and this is not engine/pipe related. In the engine runs fine, tunes fine and has no problems up until the point that you shut it off and if you let it sit a while it somehow floods then it's nit the engine doing it but something else as mentioned. The carburetor only sucks fuel when the engine is turning over which if it makes sence is pulling air over the spray bar which in essence creates a vacume pulling fuel out of the tank. If the engine is nit turning over there is no airflow over the spraybar hence no vacuum. So...to menit has to bs residual pressure in the tank forcing or actualy pushing fuel into the engine causing it to flood and flood so excessively that you hear fuel sloshing around in the pipe if i remember what you said correctly. So again this to me sounds like some type of tank related issue.

thats where i was headed next.....changing the tank. i was almost positive it wasnt the engine, it runs too good after you get it going.

I'll defer to Ron's wisdom on this, but I can't help but wonder about the plug your using. I know you said it was a werks plug, but what temp range is it and how old is it? I'm wondering if the fuel isn't completely burning off when you stop the motor. You had said that you're using the flywheel method to stop it, as opposed to pinching the fuel line or smothering the stinger. I would think that with a weaker plug that would leave some fuel behind, that coupled with the local temps not beeing blazinly hot in recent days.

im using a werks #5 plug with 1/2 a gallon on it

I can kinda see what you're getting at but that's not going to be the issue that he's having. If you stop and think about it if you turn the engine over on the box for a few seconds without the igniter attached you still do not get enough fuel in the engine to pour out of the pipe like he was describing. What he has is a clasic pressure issue with the tank, basicaly it is pressurized by the line coming off the pipe while the engine is running. When he shuts his engine off the tank is not venting so it is under pressure still then the tank cools and shrinks which forces fuel up the line and into the engine flooding it.
